Operation mode of single power unit providing auxiliary power

Abstract

Abstract: Abstract:Due to continuous heavy snowfall weather in area of north china, the three of four output transmission lines of Togroh Power Generation Company Limited tripped, and six of total eight units were shut down. If the only remained output transmission line trips, then the all output transmission lines of the plant will interrupt. Further, a severe situation may occur, in which the auxiliary power supply and auxiliary steam source are all interrupted. Some effective measures were adopted to ensure one power unit to operate normally, then the auxiliary power supply and auxiliary steam source will be available for other unit restarting.
