摘要
针对目前高压并联电容器组不平衡保护存在"死区"的问题,提出通过增加一相TA,利用新型微机保护进行编程的改进方案,分析该方案的计算原理、定值整定方法,指出该方案的可行性及具体实施中应注意的问题。
According to dead zone in unbalance protection of high voltage parallel capacitors,this paper put forwards a new improved project that new type micro-computer protection programme through adding a side TA,expounds the calculation principle and setting value adjustment method.This paper considers that this project is feasibility,and indicates the mentioned problems during implement.
