【Abstract】 This paper proposes a Hybrid Reactive Power & Harmonic Compensator(HRPHC) based on the active power filter(APF) and the reactive power compensator(RPC).HRPHC has the advantages of both APF and RPC,which are higher accuracy and larger capacity and being able to compensate reactive and harmonic currents smoothly.This paper also presents a new simple and quick method of generating the reference current.This method exacts the positive sequence voltage from the asymmetrical,distorted source voltage and generates the reference current using this voltage.This method can effectively compensate the positive and negative sequence current and harmonic currents.A software simulation has been conducted and the simulation results convince the validity of the proposed HRPHC and reference current generation method.更多还原
