摘要
探讨了变压器零序过流保护整定计算中可能出现的零序电流反向问题,分析了其产生机理及其对保护的影响,并在此基础上对常用的变压器零序过流保护整定方法进行了改进,计及反向零序电流的影响,满足保护选择性的要求,同时将改进后的变压器零序过流保护整定方法成功运用于开发的变压器保护整定计算程序中。
This paper presents the issue of the zero-sequence current reverse in the coordination of transformer zero-sequence current relay and analyzes its reasons. Based on the above, an adaptation of the common coordination method for transformer zero-sequence relay is brought forward to take into account the influence of this issue. And this adapted method has been successfully applied into the transformer relay protection coordination software.
