Performance Analysis of Shunt Active Power Filter Based on PIDA Controller

Abstract

This research paper addresses current harmonics mitigation using shunt active power filter. Due to excessive use of power electronic converters (PECs) and non-linear loads it is observed that power system voltage and current responses become non sinusoidal and thus produce waveform driven power quality issues like voltage harmonic and current harmonic. The active power filters are gained attention to mitigate the harmonics, power factor correction and reactive power compensation. Three phase reference source current is determined with active reactive power (P-Q) theory with PIDA (Proportional Integral Derivative Acceleration) controller as DC bus voltage regulation. PIDA controller is an extended form of proportional integral derivative (PID) controller. The extra term 'A' define for acceleration with this new phrase a closed loop network can respond quicker (less settling time) with lesser overshoot. The proposed system is simulated using MATLAB/Simulink. An effective compensation solution with defined harmonic limit is obtained to improve power quality as per electrical regulatory commission and standards such as IEEE 519-1992.
