Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. This model presents the analysis and simulation using Matlab Simulink of a three-phase four wire neutral clamped active power filter (APF) compensating the harmonics and reactive power created by nonlinear balanced and unbalanced low power loads in steady state and in transients. The usefulness of the simulation approach to APF is demonstrated so APF designers have a better insight using Matlab Simulink in order to develop new APFs.
its missing the discrete butterworth filter
and the link u replied with isnt working
yes .. thank you mr.Amit sir.. it works perfect.. am using matlab 7.8 (R2009a)version...
how can i generate sine and cos function from a pll block
it's not work
please ..i do need this subject for my final project, i alredy make in d-q teory but the result not change, current and power after filter still higher than no filtered
with load 1KW current must be 5A and 220VOLT but your program current running 1000A, current increase masively, can i know why this happen??
Check out SAPF for 3 phase 4 wire systems.
check out the above link
working sapf with thd below 5%
It is working but the THD of the source current remains 28.61 %. By IEEE standards it should be below 5%. Provide your suggestion to this id email@example.com I will send those source current waveforms and the THD% VALUES for the same to your mail id.

Failed to find 'Discrete Control Blocks/Discrete 1st-Order Discrete Filter' in library 'powerlib_extras' referenced by 'active_filter/Rectifier Control/Current Regulator PI/Discrete 1st-Order Discrete Filter T=1ms' can you provide some solution?
Bt it is wrkng in my system @utkal...plz tell wt error is it showin
this is not working ...
please modify and post it again.
with reference to the suggestions and feedbacks provided by the users the program has been updated.please have a check and apologies for mistakes
