Analysis on tripping process of output transmission lines

Abstract

Abstract: Abstract:Three output transmission lines of Togtoh Power Generation Company Limited tripped successively due to heavy snow weather, and this caused emergency shutdown of multiple units. The accident situation was expounded. The reasons of generator tripping leaded by output transmission line tripping and the harm of output transmission line tripping were analyzed. The emergency countermeasures were formulated, and the normal power transmission of the line was ensured.
