ABSTRACT: Due to environmental
conditions, the wind power generation is fluctuating in nature. This affects
the electrical network interconnected with these systems. When the wind power
generators are connected to the nonlinear loads, there is distortion in the
waveform. These distortions should be within limits according to national and
international guidelines framed for power quality. This paper presents a mitigation
technique with a shunt active filter, which reduces harmonic distortion to the
permitted limit. Sine pulse width modulation (SPWM) control scheme is used to
control shunt active filter. This technique eliminates harmonic distortion and
maintains unity power factor. The simulation for proposed method is carried out
using MATLAB/SIMULINK and results are validated.
