一起因干扰引起的母差保护异常分析

With Lightning Induced Fault Protection Action Analysis

文章通过对一起由于接地选线装置行波干扰引起的BP-2B型母差保护异常,对故障动作报告以及其他相关设备运行状况进行分析,找出故障原因,提出适当的解决方案并消除隐患。在此基础上,尝试查找BP-2B母差保护的"开入元件"抗干扰措施,找出现有直流监察系统直流接地自动寻路方式存在的隐患,为处理类似异常提供现实的经验。

Article by traveling wave interference due to grounding selected-line equipment with BP-2B type bus differential protection caused by exception,On failure action reports as well as other health related equipment for analysis,identify failure causes,And Come up with appropriate solutions and eliminate risk.On this basis,try to find the BP-2B of Busbar differential protection ＂opening into the component＂ anti-jamming measures.Identify existing DC monitoring system for DC system grounding way of automatic optimization road risks,provide real-world experience to handle a similar exception.
