Analysis on reason and action process of 500kV line tripping
DAI Shuqin

Abstract

Abstract: Abstract:The rain and snow weather caused the transmission line tripout accidents of the YuanBa Line I, YuanBa Line II and YuanAn line I of Hunyuan 500kV switch station. The reasons of tripout accidents and the tripping process were analyzed. Effective countermeasures were adopted so as to ensure the generator units of Inner Mongolia Datang International Togtoh Power Generation Company Limited to operate safely as far as possible.

Key words: Key words:“11.5”accident, reason analysis, subsynchronous resonance, blocking filter, torsional vibration stress protection, asynchronous selfexcitation, modal I, modal II
