Abstract

Abstract: Abstract:The operation mode of 500kV system of a power plant was introduced. The configurations of the 500kV line protection and the 600MW unit protection were expounded. The process of the line switch maloperation accident and the reasons of the accident were analyzed, and the precontrol measures were put forward.

Key words: Keywords:switch trip without fault, selfignition of pulverized coal deposits on cable, reason analysis, precontrol measure
