Power Quality Improvement on 11 kV/440 V Distribution System Using DSTATCOM

At the PCC and source side current and voltage harmonics is compensated by utilizing, a distribution static compensator. In this work, we also compensated voltage control and reactive power correction. An improved reference current switching signal is suggested using a synchronous reference frame control technique. The analysis is done on 11 kV/440 V three phase four wire unbalanced nonlinear load distribution system. The DC link voltage and harmonic reduction, of the suggested distribution system performance is compared with the PI and fuzzy logic controllers. Harmonic distortion is reduced and reactive power is successfully compensated with the suggested method. This simulation results are obtaining by MATLAB/SIMULINK software.
