A Design and Simulation of Hybrid Power Filter for ASD Loads Based on Instantaneous Power Compensation Theory

가변 속도 드라이버 부하에 대한 순시 전력 보상을 이용한 복합형 전력 필터의 설계와 시뮬레이션

This paper deals with the design and simulation of the hybrid power filter to compensate reactive power and harmonic components of nonlinear load. Control target is a 3-phase diode full bridge rectifier with L-R-C nonlinear load, this load is assumed adjustable speed driver(ASD). The hybrid filter consists of a shunt active filter, shunt passive filters and series inductors. Control algorithm is based on instantaneous power compensation theory proposed by H.Akagi and etc. The result from simulation shows the hybrid filter is superior than other filters on the point of compensation performance and low cost. The PSCAD/EMTDC 3.0 is used as simulation tools.
