摘要
针对几起500kV变电站和电流回路保护误动事件,分析误动原因,并提出解决方法,为变电运行维护工作提供借鉴。
Combined with the fault operating cases of 500 kV substation sum current circuit protection,the reason of false action was analyzed in-depth.The maloperation of the various factors was analyzed concretely and the solution was proposed.The references were provided for operation and maintenance in substation.
