单台机组保厂用电的运行方式

Operation mode of single power unit providing auxiliary power

由于华北地区连降暴雪,导致托电公司对外输电的4条出线3条跳闸,全厂8台机组6台机组停运,如果唯一1条出线也发生跳闸,将会导致全厂出线中断,严重时可能会造成全厂厂用电和厂用汽中断的严峻局面。采取了保证单台机组正常运行的有效措施,达到了其他机组启动时厂用电和厂用汽稳定供给之目的。

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.
