Mitigation of load harmonics from grid connected wind turbine using shunt active power filter

The increasing utilization of power electronics controlled devices in power system has increased distortion level in current and voltage waveforms in the form of harmonics. The increase in harmonic level also affects the performance of generator, thereby reducing its efficiency and lifespan. In this...
