一次特殊故障的继电保护动作行为分析

Analysis of Behaviors of Relay Protection Devices Related to a Special Fault

详细分析了高频保护区外故障,高频保护及后备保护动作情况,故障电网系统内其他线路保护动作情况,对以后保护实际工作有一定的借鉴意义。

This paper analyses in details the behavi ors of the high frequency protection devices and back-up protection devices in the case of a fault occurs beyond the protection region of the high frequency protection devices. Furthermore, the behaviors of the power line protection devices which work in the faulted grid are analyzed either. The analysis results may be referred in the following works related to relay protection.
