Wind Turbine Model



05 Nov 2009 (Updated )

Wind turbine model including blades, nacelle, pitch and yaw actuation, generator and control system.

| Watch this File

File Information

This file contains a wind turbine model. It includes a three-dimensional mechanical model of the tower, nacelle, and blades modeled in SimMechanics, hydraulic pitch actuators, electrical yaw actuators, a simple generator and electrical grid model. There are a number of supporting models included that show how to develop each of the systems separately and integrate them into the overall model. The level of fidelity for each subsystem can be varied as you work through the design.

To use this example, you will need to read the README.txt file. Run the script, “startup_Wind_Turbine.m” to get started.

Watch this four part webinar series to learn about this model:

Can anyone please help me in designing a system in Simulink for pitch control with blade load only? I am not considering the power part but only the loading. I want to test the system under static and dynamic conditions but I am not familiar with the equations to use. I am also not considering the yaw mechanism. It is a simple design but I still need help with the mathematical modelling.

Hi Steve,

Thank you for your work! However, I have a problem. I have a 64 bits Matlab. When I run your model, it gives an error. How can I resolve this problem. This is the message:
The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the new
API. You can find more information about this at:
Building with the -largeArrayDims option enables the new API.

Is there any manual to deal with this model?
I am struggling to follow the video, but it's not easy. And html link is not working. Any guys have idea for this?

I want to create some fault cases of the subsystem to see how it responds and therefore have some question: is there any way to change certain parameter during the simulation? For instance, simulation time is 80, I want to replace the leakage area of 4-way directional valve in hydraulic pitch system with another value at 40 second. Is it theoretical doable?

I just finished the settings and got it behaving well with matlab R2013a. Hope this helps mac OS 10.9 users. Instal Xcode 5.0.2,
1. As presented on , run the following commands on matlab R2013a command window:


cd bin


2. Save a backup copy of this file somewhere in case you make a mistake and you need to revert your changes.

3. Scroll down to the Mac (“maci64”) section of this file, beginning around line 120.

4. Replace all instances of 10.7 with 10.8; there are four of these in all (a fifth may be found in comments only)

5. Save the file, then execute the following command in the MATLAB Command Window:

mex -setup

6. Change the matlab current work directory to the equivalent unzipped folder for matlab R2013a.

7. open the file “startup_Wind_Turbine” and change all the "\" by "/"

8. Save "keep a backup of the original "startup_Wind_Turbine" if you have deleted the original zip file"

9. Follow the instructions in the README.txt file and you will have it all done.

Hope it helps

@Sepideh: Yes, of course I did, It has successfully done miss Sepideh and I'll defend my work less than one week later... (my first comment that didn't show up) ;)

19 Apr 2013 MohammadReza

@Sepideh: by the way, I'll glad to help you to solve your problem

18 Apr 2013 Sepideh

Thank you, this project is really useful.
@MohammadReza: Did you solve your problem? You know, My project is designing pitch controller for wind turbine by robust fuzzy controller method as well.

@mohammed reza:This is Priyanka,im pursuing Btech final year.My project involves simulating the physical model of a wind turbine which is in our college.
What coulld be the procedure to simulate each and every component of a wind turbine ,as im new to simulink.Kindly help me out to solve this.

What coulld be the procedure to simulate each and every component of a wind turbine ,as im new to simulink.Kindly help me out to solve this.

16 Feb 2013 MohammadReza

@priyanka: Simply you need to run Startup file to initiate default values and load libraries. by the way there is no simulation of this project for MATLAB 2010a it is just for 2009b, 2011a, 2012a & 2012b. You may need to install different version of MATLAB.

16 Feb 2013 priyanka

@mohammed reza:i am having problem when i run the Startup_Wind_Turbine.m file. it is unable to compile. When I run the .mdl file directly it open up the complete model but when i simulate it, it gives some error: Failed to find library 'Wind_Lib' referenced by 'Wind_Turbine/Blade Load'. This library must be on your MATLAB path.

But this error is solved when I added path in MATLAB. Now when I run the simulation in simulink I get error:
"Expression WT_Params.Main_Controller.wind_speed_cut_in_lower' for initial value of data 'wind_speed_cut_in_lower' (#66) did not evaluate."

15 Feb 2013 MohammadReza

@Steve Miller: or How can I force turbine to work only in Generating State...

15 Feb 2013 MohammadReza

@Steve Miller: I think my last comment didn't pop up, I already managed to replace pitch controller with my fuzzy controller in Pitch Controller block, but there is a problem with Turbine State Machine in Main Controller block. when wind speed gets more than 25rpm, the turbine goes to brake state. my fuzzy controller handle these state automatically. I already changed input value for wind speed to solve this but I know it's just a temporary solution! How can I bypass Main Controller section or change the default values for turbine_speed_cut_in, wind_speed_cut_in_upper and wind_speed_cut_in_lower? Thanks...

15 Feb 2013 MohammadReza

@Steve Miller: In a simple word, I need turbine works only in Generating State...

15 Feb 2013 bab zagro

very good

15 Feb 2013 Steve Miller

@MohammadReza -- concerning the negative power, this model does not have any logic to control when the generator is connected to the grid. As a result, there is a significant transient when we simply close the breaker when the turbine is near the appropriate speed. The unexpected sign is because the generator is actually driven by the grid for a short period of time.

15 Feb 2013 priyanka

@mohammedreza:I ve already installed matlab R2010a,initially i tried to run startup..but im getting error .
.Kindly help me to solve this

15 Feb 2013 MohammadReza

@priyanka: Can you specify the error details?

15 Feb 2013 priyanka

I ve matlab R2010a,im not able to run this model.Kindly help me to solve this

12 Feb 2013 MohammadReza

Another question, If I'm right We have a simulation for 2MW wind turbine but the y axis of output power diagram in Generator Scope have some value between -0.3639 and -0.3635 and power values are in this range! I'm confused...

12 Feb 2013 MohammadReza

By the way, I sent you an email with the subject "Some help please..." two weeks ago, I'll appreciate if you take a look on that...

12 Feb 2013 MohammadReza

Thank you, That's great...

12 Feb 2013 Steve Miller

@MohammadReza -- when you first open the model it is configured to run with only the mechanical load from the generator and omits the electrical system. To include the electrical power generation, you need to go into the Nacelle subsystem, right-click on the Generator Block, and select "Block Choice" / "Full". Then you will see output on the Power Scope.

12 Feb 2013 MohammadReza

Hi every body, I got a question, How can I see output generator power (P(W)) in this model? I found that there is a power variable in Generator Scopes but the Power diagram shows only zero value! what is the problem in this model?

06 Sep 2012 JOLIA

I successfully run the model and review webinars and it is very very usefull and it is really great work...
But I really interested in Yaw control than Pitch control so if you can send me the yaw controller_testering it will be a really great thing.
As I try to change in model yaw control system but it is not available to edit in a subsystem....
thanks in advance

Thanks for reply, I've R2010a Version of matlab, is there any procedure to download SimDriveline exclusively & to integrate with Matlab Version R2010a.

Thanks in Advance

29 May 2012 Steve Miller

Ashish -- you need SimDriveline to run this model. Make sure you are using the right MATLAB release. Before R2011a, use the R2009b version, after R2011a use the R2011a version.

15 Mar 2011 Tiago

Hi again,
Gorget the previous problem, i have already solve it.

14 Mar 2011 Tiago

I'm having trouble running the application on a windows 7, 64 bits, PC.
The only file available is "Wind_Turbine_sfun.mexw32", and I am not sure if I have all the files required to compile the .mexw64 file. Could you send this file?
The simulink main file is crashing with the error "Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler.". I am currently trying to install a compiler.
Thank you for your help.

09 Mar 2011 Mohd Mohd

why i can't open file in ???
can u help me???

28 Jan 2011 Steve Miller

If you are having trouble running the model, please remember to run startup_Wind_Turbine.m first. Many of the errors you are getting are because you are opening the model directly. Errors concerning "wind_lib" will be solved if you run startup_Wind_Turbine.m Read the README.txt file for more information. Enjoy, --Steve

pls say something

01 Jan 2011 teddy mi

hi Steve Miller

i appreciate your "Wind Turbine Model"
and i have a problem when i start simulation of this model
its error massage says
1) failed to find library 'wind_lib' refranced by 'wind_turbine/blade load' this liberary must be in your MATLAB path
2)failed to find library 'wind_lib' 'wind_turbine/blade load/ lift and drag' this library must be in your MATLAB path

please send me by by including those library's email

05 Sep 2010 Mohamed abo el ella

Dear sir,
i am working on turbine control project using Lidar technology , and i downloaded this model to perform my control algorithm for individual pitch control on the turbine.
i have some questions which i hope to find answers for it:
1- when i run the model without adding the generator the model works good and when i add it errors occur in the following part
wind_turbine/nacelle/generator/full/asynchronus machine pu units/ electrical model/phasor/positive sequence model

wind_turbine/nacelle/generator/full/asynchronus machine pu units/ electrical model/phasor/positive sequence model/mux 3.

and the problems is in the dimensions

what should i do to solve this problem

2- is it possible to replace the controller for yaw motor and pitch angles with another controller which i am working at and also the generator used
