摘要
通过对一起由刀闸引起母线接地故障,母差和线路保护动作报告和故障录波信息的分析,讨论了在不同情况下开关动作速度对继电保护动作行为可能产生的影响,提出了防保护误动的建议。
By the analysis of protection report and fault wave record,breaker speed＇s influence on relay protection operation of a bus grounding fault is discussed. Some improving suggestions to avoid incorrect protection action from its taking place in this paper are put forward at the same time.
