| 摘 要： | 针对三相不平衡负荷会对电网安全运行造成巨大危害,建立了三相四线制下不平衡无功补偿算法。该算法简单实用,在仅知补偿前三相有功功率及无功功率的情况下就可确定各相所需补偿值,而且补偿后电网损耗大大降低。通过设计实验方案,搭建物理实验平台,最终用实验数据的分析和仿真验证了该算法。实验结果表明该算法可对三相不平衡负荷,同时实现无功功率补偿和负荷平衡化,获得较好的电能质量,并达到较好的节电效果。

| Abstract: | In view of the grate harm that caused by the three-phase unbalanced load,the algorithm of unbalanced three-phase load reactive compensation of 3-phase 4-wire is built.The algorithm is simple and practical,the compen-sation value can be got when three-phase active power and reactive power are known,and the grid waste can be drop grately after the compensation.This paper designs the experiment project,builds the experiment platform,analyses and simulates the experimental datas.The experimental and simulation ... |
