Study of power quality compensators in power system

摘要

This paper discusses the different structures of power qualitycompensator (PQC), and mainly illustrates the influences on itsvoltampere (VA) rating and compensatory performance, which is exhibitedunder the condition that the AC input of main circuit's DC supply isextracted from the system or the load side. Meantime, the impacts on PQCare also analyzed when a three-phase rectifier or PWM rectifier isadopted as the DC supply. The simulation results verify the correctnessof the theoretical analysis
