摘要
分析了电力系统不同短路情况下,各序电流分量的相位对相差高频保护的影响及相差高频保护存在的缺陷,从而得出相差高频保护操作电流的选择以及改善相差高频保护性能的措施。
Based on the analysis of the influnce of every sequence electric current component phase on the phase difference high frequency protection in different case of short circuit on powers system,this paper presents the selection of the phase different high frequency protection operation current and includes the defects in the phase difference high frequency protection failure
