Tej DalwadiSimulink Based Modeling, Design and Performance Evaluation of

PMSG Based Wind Energy Conversion System

1 2 Neetu Singh , Dr Bhupal Sing one can see this paper for better under standing

Tej DalwadiGood work dr siva it has helped us understand our project more clearly

Tej DalwadiClement HianFor those who cannot run the file due to the expression error, you can fix the issue by replacing the wind turbine (inside the wind generation block) with the wind turbine inside the simulink library. After that, keeping the gain block as -1 after the shaft torque, then it should work properly. Other solution is to change the function of wind turbine from C1 ~ C6 to any Cp coefficient used by other paper

Clement Hian@AJAY CHANDRA DORAGARI

Are you talking about the case of varying wind speed or constant wind speed? For me, during the constant wind speed profile, the power still goes to zero slowly, and the pitch angle controller is not working (since the wind speed is constant). If you have fixed the issue, could I have your email so that I could have more information on solving this issue?

Regards,

Clement

AJAY CHANDRA DORAGARI@Clement Hian

yes i have faced the same problem initially thats happening because of pitch angle angle control .You have to properly choose the base speed and the ratings of pmsg , try to change the parameters of pmsg so that your rating of pmsg and wind turbine should match if not the speed of the set gets increased then the pitch angle angle control tries to correct it

Clement Hian@AJAY CHANDRA DORAGARI do you face the problem of the power slowly goes to zero?

Sansari007@Clement Hian. Does I have fucked your mother! If you had understood something, you could have been write it easily for others. Nonsense people

Clement Hiansansari truly dickhead

AJAY CHANDRA DORAGARIFirst of all thank you sir for giving a pmsg based wind generator this model helps in understanding in how to design a wind generator. You can ask matlab provides dfig based model but for lower ratings you use a direct coupled pmsg to lower the losses and economics since it is direct coupled machine you have to careful in giving the appropriate torque because the speed is directly fed back to wind turbine input and because of pitch angle control you may not get an expected output if just change the base torque go through the papers provided by Dr.Siva you will be fine and you will understand the how to select speeds for different ratings Even i asked Dr.Siva for help in designing a hybrid grid but he might be a very busy man I didn't get any reply then I went through his contributions in matlab some of his models helped me to design a hybrid grid supplying 200kw load (it may be nothing special but i can say i have done it on my own and designed my own control scheme for diesel generator and it was done only after understanding on how to design by standing his reference paper) so I guess he helped in an indirect way and this way i got to learn it on my own and yes ofcourse it takes time and yes his models helped me.So take it as challenge if you use properly humiliation is a greatest motivator take an example of story in mythology series of mahabharath of eklavaya and arjuna im sorry if said something wrong or used too many words

Dr. Siva MallaSee MR. Sansari007: Are you a learner? means? do you want to learn if I explain each and every thing? then its called as under graduate student not a learner or researcher. Because, I provided respective reference in 2012 itself. Can't you peoples read all the comments?, you peoples wants direct answers, even some peoples can't analyze the systems also. Instead of commenting on me like Mr. Shamsher Ansari, he should at-least read the reference paper which I provided. Are you not feeling shame to ask foolish questions even don't know about different between Motor and Generator. The simple thing that Frequency is input to motor and out put for a generator. Then how some one can assume 20*frequence/P will be for generator and they are assuming Frequency a input. I used Buffalo because, it will be suitable to who required direct answers even not analyzing or reading references. I can appreciate if some one will a the questions or doubts in that IEEE paper. Simple they wants to criticize me. First answer me for this comment: "I have gone through many uploads of Dr. Shiva and find out that his intention is only to trap the researchers by helping less without any clarification.....Thank for such a wonderful mindset."

If I uploaded useful models then is it for trap some one? yes, it may be my fault to give you models with free of cost and explaining to foolish peoples who don't deserve it. I cam calling those peoples as sheep. By reading my comment, some one can realize before commenting. Don't simply say you are a learner. we all are learns, but true learner will ask the questions after reading some articles. Not like they simply required direct answer without reading any references. Till you are asking me to give a explanation, but its your duty to read some more references. Don't waste your time on commenting ion me, instead you please read some of my articles to get more information. For fan also depends on poles. I assumed 2 pole pairs for understanding purpose. I hope you didn't see even we have 3000 rpm fans. Even fan is not synchronous motor. so rotor speed depends on many factors. If I explain who will cares? I given reference tel me who reads? if some one read then no such comments will be appear here. Now, I given aggressive comment, then peoples can realize. See, if learners like you commenting that model might be wrong, then other scholars will not be interested on this. by reading previous comments many scholars might spiked this model. instead of saying the model wrong, one should analyze it. And finally it is not uncompleted equations by Mr. Shubham sachen. It i one way of approach, I think you didn't get our logic and way of approach. Many peoples have their own approaches.

Sansari007Let me conclude: to calculate the base speed in rad/sec just use follow the equation " Tip-speed ratio(lambda)=[{(rad/sec).(radious of the blades)}/wind velosity]. from the lamda vs Cp curve choose respective lamda value. Here Dr. Siva choosen 7.4 which gives 152.8 rad/sec base speed.

request to all upcoming researcher please read the Dr. Siva's comments and waste your time to recognize a new "buffalo-cum-sheep" by analysing the comment made by Mr. Shubham sachen and referred by Dr. Siva" . May be Mr. Shubham was a learner like me but what about Dr. Siva?. Shame a Dr. honored man is uses such words for a learner.

Sansari007Sorry to write again, as Dr. Shiva is still wrong by referring the uncompleted calculation by Mr. Shubham sachen and it could create confusion among upcoming ….So, please read the reference suggested by Dr. Shiva "Md. Enamul Haque, A Novel Control Strategy for a Variable-Speed Wind Turbine With a Permanent-Magnet Synchronous Generator, IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS, VOL. 46, NO. 1, 2010" and follow the equations from (1)-(6). Everything will clear about the base speed calculation.

Sansari007To,

Dr. Shiva, thank you for replying. I think instead of writing nonsense you could had been explained the entire concept. May I do not have much knowledge as you have gained but please let you know that " as you commented...'What you used the equation Ns=120f/p is for motor, not for generator" this equation is equally applicable to motor or generator, might be I am wrong in case of PMSG prospective as I don't had much knowledge on that. Aslo.........as you commented..."in our home, the fan is rotating nearly with 1200 to 1500 speed,"......here also you are wrong......generally we have 300-400 rpm fans....(except special cases...).

Let me clarify sir, why I used " nonsense" because the thing which could be answered in few words for that you have taken 1000 words. Thank you sir, however I feel I am nothing in front of you but not a Zero.

haider aliDr. Siva MallaDear Ansari and all, please see my comments which are divided in to 4 parts. sorry for my poor English, you peoples can better understand if read it carefully and completely. sorry for such a long comment or reply. If you realized then you can say sorry, or else you can continue your comments without knowledge on this model.

Part-1:

Dear Ansari S: thank you for a wonderful comment and your uneducated explanation about base speed. Sorry for using uneducated, because I think your faculty or teachers are not properly teaching you regarding motors and generators. What you used the equation Ns=120f/p is for motor, not for generator. Please tell me whether you know what is the input to generator? And what is the output of generator? Is frequency is input? Is speed output? . I am asking this basic question to you because how much frequency you can give to generator to calculate speed? . See, first you should know how much wind turbine speed? Do you saw any wind turbine in real life? I think you didn’t saw, if you saw and commented as Ns=12f/p then you are unfit to do the research on wind turbine based PMSG. I am saying it because, in our home, the fan is rotating nearly with 1200 to 1500 speed, but we unable to saw the blades when its rotating with high speed. Even we can’t observe properly for 600 rpm also. But when wind turbine in real life, clearly we can see the blades and there is no gear systems for PMSG which we are using mostly. Then how you can say 1500 rpm nearly wind turbine rotating? And see, I used PMSG in matlab and just open it, I think you didn’t saw the parameters of PMSG, but you want to do the research on PMSG, how funny you are lol?. I used poles 10. If you assume 50 hz frequency then how much speed, (it is not motor, but according to your theory and comment) Ns=120*50/10=600 rpm is equals to 62.8 rad/s. is it I used? How much funny you know? Before you given comment or equation can’t you just check it? Okay, any way, do you know if its 152.8 then how much frequency required for 10 pole machine? 122 Hz nearly. Do you really think the PMSG cn generate output with 122 HZ. If it’s so, how much wind turbines have to rotate PMSG? Have you ever seen this much speed wind turbine rotting in real life? .

This is showing how much knowledge you have on PMSG. See, for this kind of peoples who doesn’t know the basics, should I waste my time by giving reply?. I am not criticizing you, just I am informing you the standards how you peoples are having. Just I will mentions many peoples who commenting foolish and without knowing basic fundaments. Please read Part-2:

Part-2: From the comments:

1. Mr. Ali commented on 25th April 2012 for reference paper. I given reply on 27th April 2012 within 2 days and I given the reference of my paper and mentioned to check the referencen on those: The reference which is mentioned 153 is based speed is : Md. Enamul Haque, A Novel Control Strategy for a Variable-Speed Wind Turbine With a Permanent-Magnet Synchronous Generator, IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS, VOL. 46, NO. 1, 2010.

This above reference having all the data and the speed is mentioned 153, but its slightly wrong, I calculated it is 152.89 from the basic equations.

2. On 5th Aug 2013, K. Byahatti asked me my email for help, and I provided my mail ID on 7th of the same month, even many of my models having my email ID.

3. Firstly Mr. Yuya raised the question for speed 152.8 on 12th Oct 2013. But I didn’t provided the reply, for why, I provided valid explanation in part-3.

4. On 12th Dec. 2013, a great professor cum cunning fellow. I am using this cunning word because, his intension is to degrade our credibility by saying this is copied model and already having in Matlab 2012 version. My great reply to this dog is: the version matlab 2012b released in Sep. 2012. I uploaded this model in 10th April 2012. You just think how I can use the model which is having in Sept. 2012 version in April 2012?. Is it logic? And okay you can say 2012a released in March 2012. For this my answer is if a version released in March, it will take at least 2 months to buy my institute, then how it is possible and I developed this model in 2008 version as already mentioned while uploading the model. Even at least 2 months will takes to develop the model in matlab, so, if 2012 released in March, we cannot build this model on or before Aug. 2012, but I uploaded in April itself. So, logically his comment failed. Even I provide my paper which is published in IEEE is in 2011 published. Then how we can publish and design a model in 2011 if version released in 2012?. No one are object this point by commenting, because you all buffalos required my models, explanation only. By using this, you will get some benefits.

5. Now another buffalo cum sheep came and commented his name is: Stephanie. I don’t know how is given this comment, even he doesn’t know the motor and generation, since the equation he provided is not related to any electrical machine. Is speed =2*pi*60/number of pole pairs? He doesn’t known even ethical formulas and he is not at all eligible for Electrical engineer. Moreover, this sheep mentioned, there is no MPPT. I didn’t mentioned anywhere as it having MPPT. It is just converting electrical power from mechanical through wind turbine and PMSG. Why MPPT will effects on analyzing this model. Furthermore he given statement that its trapping because nice output. See, sheep, we can get nice output by keeping wbase as 170 also. Then why I used 152.89? and our great researcher Ansari even failed to analyze this simple logic and confirmed that its trap. How these foolish peoples behaving while analyzing the models? Is these scholars are really eligible to teach us in future?. Its shameful on them.

6. Another lazy fellow whose name is Sohaib H asked me the upgrade version in 2014b. his commented on 2015, I don’t know why he didn’t asked the model in 2015 version?. I think he having 2014. So, for every year I need to upgrade model for these lazy fellows?. Why can’t he install 2008? He just wants in upgrade version, but he can’t waste time to install 2008. He can install 2008 and can rebuild it in 2014b if he really wants. And Mr. Ansari, for these peoples you want that I need to answer?.

7. And I have a comment from only one real scholar name as Shubham Sachan: he asked me the question for base speed 152.89 on 23rd March 2016 and he given his analysis on 9th April 2016. See, he is only doing real research and he done some analysis to get the answer. Few modifications required, however, he came 90 percent near to answer. I appreciate him. He only finds, that PMSG as generator and there is no relation between frequency as input to calculated speed. From his analysis, wbase is related to turbine parameters only, even not related to PMSG. Its completely true.

8. After Shubham explanation again EST commented on 29th May 2018. I don’t know why again he asked, I think he doesn’t want to waste time by reading comments, he just want direct answer.

9. Now the world’s great professor came to explain by his worthless analysis. Even he doesn’t know the difference between synchronous machines and asynchronous machines. How slip came to picture in synchronous machine? Only god can create slip based synchronous machines. In Ns=120f/p, here P is number of poles and he take ‘3’, how this odd value came I don’t know. Even in PMSG used in this model clearly says pole pairs are 5. And how he decide 50 hz is frequency of PMSG?. See, Mr. intelligent, PMSG is taking mechanical power and generating electrical power with particular frequency depends on mechanical speed, number of poles. Frequency is not input to generate the speed of PMSG. Then how you calculated speed by frequency.?. How you decided 50 is rated frequency, the generated frequency depends on speed of shaft, but speed of shaft doesn’t depends on frequency of PMSG. Because it is not a motor.

10. Finally our expert Ansari’s comment: Now tell me sir, is I am trapping to attract researchers? Is it any benefit for me to do that?. Should I waste my time for explaining everything to peoples who even doesn’t know basics? And difference between motor and generator?.

I will give the details answer to all whey I am not giving replies to comments in mathworks in part-3.

Part-3:

Before knowing why I am not regularly commenting in this platform just knows few things about me.

I am Dr. Siva Ganesh Malla, PhD from Indian Institute of Technology, Bhubaneswar, India in 2014. I am addicted to research from my graduate level, when I was in 3rd year B. Tech, invented solar bike in 2006 and telecasted in many news papers, TV channels and I am working on matlab since 2007. Two times my project were selected for presentation in young scientist award program organized by Indian science congress. Maximum only 8 best projects will be selected from all engineering branches from all over the India, and I am one of them and proud of that. I developed many matlab models and modeling many models which are using in Matlab library software. I mean, many models are available in matlab software is developed by me with some modifications. I was the world’s first ranker in mathworks file exchange in 2012 to 2015 many times. These are few achievements.

Now, coming to the point, even, I am expert, I am a human being. I need time for my works, I need time for my family, I need money and time for my daily activities. In maximum models which I uploaded in mathworks file exchange, I given me mail id. So, can you peoples imagine how many mails daily I am getting for requests on matlab, related to electrical field?. Even you can’t believe. Daily an average I am getting more than 300 emails. I uploaded 89 files and every month more than 2000 downloading are there on my models. Just, for you peoples, you can’t teach your class student around 60 to 70 peoples properly, then how can I handle 300 scholars daily? And why I should waste my time to explain who even doesn’t known fundamentals?. I am giving reply to only peoples who can analyze by themselves.

Just know the different between student and scholar. We can teach to students, but not to scholars. Scholars should have ability to analyze by themselves. I given detailed model and you peoples can download my papers, then why again explanation required to you?. If you can’t analyze the model by yourself then how you will become a research scholar?. If you know everything from others then what will be your contribution for new innovations?. Once you become a researcher, then its fundamental thing for analyzing the model by yourself. For example, see, Mr. Shubham analyze the model perfectly.

The best story is that: when I am working under my supervisor Dr. C. N. Bhende, once I asked him a question, but he didn’t answer me and he asked me to provide the answer next day. I thought my supervisor also doesn’t know the answer. After couple of hours, I went to sir and explaining my analysis. In middle of explanation, my guide open his gmail and shown me his draft, the exact analysis which I prepared is there with time same when I asked him question. That means, he know very well and he wants to see how I can analyze the problem. After that I didn’t asked him a single question related to my research. He is my best supervisor because he wants to me a good researcher by solving my research problems by my own, he doesn’t want me to become a lazy fellow by knowing answers with any research or study materials like you peoples. You all peoples wants direct answer, can’t even read the papers carefully which we published you peoples wants matlab models for your research work without any efforts.

For me, it is very difficult to answer for all scholars, since every day many are requesting through mail. Randomly I will answer 15 to 20 who have really to work hard on the matlab models.

Please read part 4 to get overall view of my research and true research on electrical engineering. This will helps you to do quality research.

Part-4:

Before you started research just know the fundamentals and what wrong things we learnt from our faculties who not teach us properly due to their lack of knowledge like you peoples.

1. Many teachers are saying the firing angle alpha above 90 degrees will act converter as inverter. My answer is, it is wrong, because according to formula of rectifier with L load will produce negative voltage after 90 degrees but its till DC, there will not be current as AC. Like at 180 degrees, full bridge rectifier will produce –dc voltage. Its not an ac.

2. Rectifier and inverter are different: my answer is all are converters, even rectifier with controllable switches can act as inverter, inverter can act as boost converter. This is the main thing for single stage grid connected pv system, in this, inverter will acts as dc to dc regulator. The thing is only how we are firing the switch.

3. BLDC is DC motor: my answer is its AC motor. Simple thing is 3 phase BLDC motors are there, how 3 phase will be DC?. Even BLDC is a PMSM. By working it will be performance a DC motor.

4. What is the different between AC and DC motor: my answer is nothing. Even changing current is required to generate flux. Without flux, motors can’t run. Changing current means not DC. The only thing is how we are operating will decide the motor with proper manufacturing. Even motor doesn’t know whether it is AC motor or DC motor.

5. How to calculate base speed of PMSG?. My answer is, the speed is not related to even PMSG. It’s the value to calculate the torque which is required to generate electricity from PMSG. This is completely related to wind turbine, since wind turbine is the only source to provide mechanical torque or power to PMSG in this present model we are talking about. In real time we can’t give these mathematical values. The original shaft torque will comes from wind turbine shaft. So, for calculating the base speed, its depend on parameters of wind turbine only. It is not at all related to PMSG. How input of PMSG will depend on poles or frequency or voltage ratings or any other parameters of PMSG? Hope now you understand.

Now you peoples just think how foolish analysis were done by you illiterate scholars? I am saying this because even you peoples don’t know the different between generator and motor. All are using motor equation to match the base speed. Even it is input to the PMSG. Can input depends on output? The base speed is only relation with ratings of wind and how you are coupling with generator like gear system or without gear. You just tell me how PMSG will generates 50HZ, if wind turbine is rotating very slowly?. Do you ever seen wind turbine is rotating with the speed of fan which we are using in home?.

Minimum 10 to 12 people are coming to meet me in my office every week, and by discussion 2 hours with me, they can get idea to complete their PhD. This is what my strength and analysis power.

I stopped uploading matlab model in matworks from 2016 to 2019, do you know why?. Because load pressure is more on me for these explanations with free of cost. Sometimes, I am taking service charge also, since I have to run my life. I designed more than 6000 model from 2010 to 2019. Means, nearly 2 models per day. But peoples like you, will takes 6 months time to build a single model. Just see, what is my capacity on designing models. But I won’t upload all those models, because, I don’t want to give direct and novel model to you without learning anything. If you peoples will become lay or simple learning from me, that is not a good research, it won’t be a good for nation. You peoples just utilize my models and try to analyze by your own views, then only good research will comes out.

Now my research is towards anti gravity, free energy, etc. I am saying free energy because, the law energy can’t be created will be wrong in my views, because, see, the universe is expanding every second, hence, new energy is creating every second in universe. The law may be right in our earth, but this law can’t be applicable in universe. If anyone interested to do research with me, then I will be ready at any time, but I need a good research scholar. Perhaps, I am not working anywhere. I heard with many peoples who discussed with me for an hour, they are saying, with that one hour knowledge they can work and complete their PhD. That is what I am and my research.

Sorry for this much write up, but many scholars can change their views and ideas after reading this completely, and they can understand exactly what is electrical engineering related to this models uploaded by me.

Sorry Mr. Ansari, I am not blaming you, but just analyze before commenting and telling trap. How much pressure I am felling every day, you just can’t understand. Since every day I am teaching more than 10 peoples without any money. If I will waste my time by giving answers to your foolish questions, then true scholars will be suffering more. Now, Dr. Siva Malla is not a name, its brand.

Dr. Siva MallaPart-1:

Dear Ansari S: thank you for a wonderful comment and your uneducated explanation about base speed. Sorry for using uneducated, because I think your faculty or teachers are not properly teaching you regarding motors and generators. What you used the equation Ns=120f/p is for motor, not for generator. Please tell me whether you know what is the input to generator? And what is the output of generator? Is frequency is input?

Even we can’t observe properly for 600 rpm also. But when wind turbine in real life, clearly we can see the blades and there is no gear systems for PMSG which we are using mostly.

Before you given comment or equation can’t you just check it? Okay, any way, do you know if its 152.8 then how much frequency required for 10 pole machine? 122 Hz nearly. Do you really think the PMSG cn generate output with 122 HZ. If it’s so, how much wind turbines have to rotate PMSG? Have you ever seen this much speed wind turbine rotting in real life? .

This is showing how much knowledge you have on PMSG. See, for this kind of peoples who doesn’t know the basics, should I waste my time by giving reply?. I am not criticizing you, just I am informing you the standards how you peoples are having. Just I will mentions many peoples who commenting foolish and without knowing basic fundaments. Please read Part-2:

Shamsher AnsariNo one should follow the calculation given by shubham sachan. Just use Ns=120f/P and wr=2*piNrms/60 you will get base rotor speed(wr)........................and obcourse Dr. Shiva's trap help us lot

Shamsher AnsariI have gone through many uploads of Dr. Shiva and find out that his intention is only to trap the researchers by helping less without any clarification.....Thank for such a wonderful mindset.

Xuesong WuZhangchen HUANGfor base generator speed, in the help document of wind turbine model, it is written Tm is in pu of the nominal generator torque (calculated by nominal power and nominal speed).

In a PMSG, the base speed = 120*f/(number of pole). If electricity frequency is 50 Hz and number of pole = 3, base speed = 2000 rpm (209.44 rad/s). Due to slip coefficient, it is lightly different to nominal speed. Normally you can find the nominal speed in the technical document of your motor.

So perhaps there is an error while naming “base generator speed”, it should be named to “generator nominal speed” and be found in a technical document, but not be calculated!

Zhangchen HUANGfor 2 mass drive train, here is an article to explain: https://www.hindawi.com/journals/mpe/2013/982597/

FATHI ALREMALIEdu Daryl Macerenwhat is your basis of having a 25-Ohm load?

knight999I mean can you connect it to a VSC-HVDC ?

Kamil Kryszczewiczhi everyone,

I need a simulation of wind turbine with PMSG, boost converter and mppt algorithm if anyone have it, pls send a message to me. My e-mail adress is bartek19933@vp.pl

youssef berradathank you very much

Tripurari GuptaSpeed of the Generator is continuously decreasing.

Mladen Simicwell done.. !

Ahmed RashadSPZaananda subediJake MaraksThanks @shubham, but I don't see how is your answer calculating Base rotor speed. I see a calculation of power not based rotor speed,, please help, thanks again

shubham sachanthanks @braa but I solved this and found more accurate value than you

P0= 0.5(ρAVw)*(Vw)2*cp*k

here,

according to geographical condition so I opt value according to that

Cp= .5

A=3.1416

Vs= 12m/s

ρ=1.1308

k=.000133

now here in this model rating of turbine is I Watt

so after multiplying this all just multiply wit 746W to convert it into fro Kilo Watt to Watt. you will get 152.268.

hope every body's problem regard this will be solved.

and please respect the author Siva Malla.

shubham sachanhow 152.8 value is set please tell.

shubham sachanCan you give explanation of this model specially pitch control and 2 mass drive train.

pratapsingh jadhavCan you provide an analysis of PMSG with Grid interconnected at PCC with STATCOM connected

RiniAnnSir, Is it possible for you to provide a model for DFIG based wind generator.

ibrahimYAMINE RAMDANIthank you

Sohaib HussainHi sir

I am using matlab 2014b.this file is not running on matlab 2014b....upgrade advisor could not upgrade this file..kindly send me upgrade file..my email is engrsohaib_khan@yahoo.com.

regards: sohaib

Ramprasad SHiteshi SharmaStephanieFrom Very long,The author is not commenting on the query raised on Base Speed of Rotor =152.89.

I would Like to ask from which formula,he reached to it.

According to me,Wbase should be=2*pi*60/(Number of Pole Pair)=75.3

Please,take check of all such confusion before using this model,as waveforms looks good so it's trap and also no MPPT is there.

kamilu sanusiSir Can u pls tell you got the base speed of 152.8 and also need an equation that govern the 2-mass train model. I will appreciate assiatance from every one. My email adress i sanusielect@siswa.um.edu.my

LekhrajFathulthis is good model. can you teach me about this model? i have some question for this model.

this is my email: fathulrazaksaid@gmail.com

m.nazirihi sir

how can i change rated power of pmsg to 2MW

muhamad54@yahoo.com

XuThis model is very good, but may I ask where can I get the detailed parameters of the turbine, like the rotational inertia of the rotor and the starting torque?

Thank you very much!

Venkatesh Yadavproper references are not provided despite the users request. Most of the blocks of the model is similar to that of the one presented in the simpowersystems examples of Matlab 2012 version.

dgfdfgdfg dfgdfgdfggood for me thank

upputuriupputuriThank you for sharing this model sir Dear Sir I want to model the 100 MW offshore wind arm. So how can change the ratings like generator, turbine please send me the details My email id is u.brahmi@gmail.com

YuyaThank you for sharing this model sir.

However, may I know where I can find the wind turbine inertia constant value? where can I get the wbase value which you used as "152.8".

Anyone can help me on this? Thanks

FaisalDear Sir

I want to connect this model with the grid bus and with parallel to this model i want to connect the pv arrays of 100 KW.

Can you please help me with the model and design.

Srinivasa Kishore Babu YHI Siva,

good model.i have mailed to several times but no reply frm u

Dr. Siva MallaDear Kshitiz Byahatti: Yes, you can change ratings of PMSG generator, but according to PMSG ratings you should also change wind and other ratings like L, C etc....My email Id is malla_phd@yahoo.com

Kshitiz ByahattiDear Siva,

Great model. Thank you for sharing. I have a few questions. How do we change the rating of the wind machine? Can I have your e-mail ID?

Thanks,

Mar Sousabul hasnatcan u please suggest me how to design ....2MVA permanent magnet synchronous generator...........

BNBNMHzWhy if torque will be higher(for example Tm=800000) 2model don't same?

serryThanks for that very helpful model.

The only thing that confuses me a lot is that, given the wind turbine characteristics ( turbine output power vs turbine speed ), how is it possible that for wind speeds lets say 30m/s the output power to be greater than the power for 12m/s. I might have misinterpreted the characteristic though. I would be thankful if anyone could clarify this to me.

satyajitvery nice model sir

Swasti KhuntiaMarwan FeteihaThank you for your amazing model , helped me a lot ..

Can you please support me with the mathematical equations of the mass drive train, the wind turbine model and the Pitch angle .

Ahmed lamineDear Siva,

First of all thank you for sharing your amazing work with us.

I wanted to know if I want to changed the output power to be only 500watts what are the parameters that should be changed.

also just for clarifying the scheme contains only wind+ PMSG there is no battery and other devices that are discussed in the reference you have provided.

Thank you.

JAIDEEPvery needy sir, can i have some reference other than the provided one here

BALA KRISHNAsir can we connect this model to vsc-hvdc transmission system

Shahida HasanShahida HasanDear Siva,

1st and foremost, Thank you for this amazing model. I have a few questions for this model.

1) This model is for constant wind speed right? so the pitch angle is zero

2) but if I change the constant wind speed to fluctuate wind speed using random number block. The pitch angle is also zero. Isn't have to be change a bit?

I've been facing this kind of problem for my model too. Hope you can help.

Dr. Siva MallaDear Emad Alsaedi: Send me your email ID and quarries to my mail ID. then I can help you in this regard....

Emad AlsaediDear Siva Malla. can you provide me with more papers to understand the scheme. I am asked to simulate wind power and change of frequency and the effect on the grid. on other words, how is the frequency going to change when we connect Wind turbine to a group of sys generator. I need to study the effect.

thank you

kuppili lokeshkuppili lokeshsir please send the exact reference paper of this model

zoheir tirHi, Siva. I name is Pr Zuheir of algeria Firstly thank you for sharing the amazing model with others. for reading your paper give me password of IEEE. thank you

kirannice sir ..

Irshad IsmailAnother thing is about the drive train design. I see there are some different between the designed model and the equations stated in the reference.Could you please explain to me. Thank you.

Irshad IsmailI read the article, but one thing still confusing me is the pitch angle controller. Could you explain to me how to adjust the angle. Or you can include any reference regarding this part.

Dr. Siva MallaDear Irshad Ismail: see this paper for more details:

C. N. Bhende, S. Mishra, S. G. Malla, “Permanent Magnet Synchronous Generator-Based Standalone Wind Energy Supply System” IEEE Transactions on Sustainable Energy, vol. 2, pp.361 – 373. Oct. 2011.

If you have any doubts after read this paper then I will explain.

Irshad IsmailHi, Siva. I name is Irshad. Firstly thank you for sharing the amazing model with others. But could you explain to me in detail how did you design the wind turbine model, especially the pitch angle controller section and the 2 mass drive train section. It would be grateful if you can share with us all the matters that you considered in designing this model.

Thank you.

AdelDr. Siva MallaDear Ali, Thanks for your complement. You can see this paper and references of this paper for details of this model:
