基于Steinmetz理论的三相四线制不平衡电流补偿
Three-phase Four-wire Unbalanced Current Compensation Based on Steinmetz Theory
摘要
Abstract
Because of the existence of zero sequence components,the unbalanced compensation of three-phase four-wire system is more complicated than that of three-phase three-wire system. The compensation method of symmetrical component analysis method based on Steinmetz theory in three-phase three-wire system load balancing compensation is considered in the three-phase four-wire system unbalanced load current compensation. Moreover,the compensation mod⁃el of three kinds of constraint equations is given. In the three-phase four-wire system with the three above constraint equations,attempts are made to compensate the zero sequence and negative sequence current for star-connected load, and increase the system power factor to 1. Finally,the Matlab simulation results show that the proposed compensation theory can not only keep the unbalanced current balanced,but also make the power factor of total system be equal to 1 approximately,which proves the correctness of the proposed compensation theory.关键词
