This paper shows the method of improving the power quality using shunt active power filter. In order toprotect the supply system from current harmonics, we have to use the active power filters. These are used tocompensate the reactive power compensation, but the performance of active power filters are based onvarious control strategies. This paper presents the complete examination to estimate the working of SHAF forgenerating the current references under steady and transient for balanced, unbalanced and non-sinusoidalconditions by using PI controller. The P-Q theory and synchronous reference frame theory, which are widelyused in SHAF. The most validate results obtained by simulation with matlab/simulink software are carriedout with PI controller for P-Q control theory for various voltage conditions like balanced, unbalanced andnon-sinusoidal conditions and dynamic load changes.
