Optimal Compensation Models in Cophase Power Supply System

  • Received Date: 09 Mar 2009

  • To balance the three phases,filter the harmonics and compensate the reactive power in a cophase power supply system,two optimal compensation models were proposed: the minimum waveform distortion model,which can get best waveform quality,and the optimum resistance model,which can get optimum load.Then,the compensation effects of the two models with distortion voltages were analyzed by simulation.The results show that the former can only get fundamental active current,and the latter can transform an unbalanced single phase into a balanced three-(or two-or four-) phase resistant load.The two models have the same compensation characteristics under voltages without distortion and unbalance,and there are differences under voltages with distortion and unbalance.
