摘要
在简述基于中值滤波的暂态量方向元件原理与算法的基础上,分别研究了双端方向元件性能上的相互配合问题和两端闭锁信号传送的相互配合问题,结果表明只要故障时保护正确启动,基于暂态量的方向纵联保护能够可靠地区分区内外故障。
The performance cooperation of two-end directional elements and the transfer cooperation of two-end blocking signals are studied on the basis of the principle and algorithm of transient directional unit using median filtering in this paper. It is concluded that only starting right when fault occurs, directional comparison pilot protection based on transient can discriminate reliably fault in zone.
