【摘要】 指出了通道误码是一个同通道长度相关的指标,分析了误码对线路纵差保护的影响,介绍了实际运行中必须解决的引起非随机误码的一些原因,并分析了通道双向延时不对称度对线路纵差保护正常运行的影响,指出用于线路纵差保护的复用通道双向路由必须一致。更多还原

【Abstract】 This paper points out that the bit error depends on the length of the multiplex, channel. After analyzing the impact of bit error on line current differential relay, this paper enumerates the defects that may lead to non-random bit errors. By analyzing the drawbacks of different transmission delay on the bidirectional route, it is emphasized that the bidirectional route of the multiplex used for line current differential relay should have the same route.更多还原
