为提高紧急救援反应能力,确保电站迅速有效地处理在110kV系统、400V厂用系统全部停电的情况。电站处于全“黑”状态、机组不能正常启动时,利用电站直流系统蓄电池、柴油发电机提供的电能完成机组启动、恢复保坝电源,对内恢复厂用电,对外配合调度部门恢复电网运行。机组黑启动不仅是电站在全厂失电情况下安全生产自救、防止水淹大坝的必要措施,也是保证电网安全生产所必需的。
In order to improve emergency response capability, ensure that the power station can quickly and effectively handle all the blackouts of the 400V system in the 110kV system. The power station is in the state of “all black”, when the unit can not start normally, use the power supplied by the power station DC system battery and the diesel generator to complete the unit start-up, restore the dam power supply, restore the plant electricity internally and cooperate with the dispatch department to restore the power grid run. The black start of the unit is not only the necessary measure for safe production and self-help of the power station under the condition of losing power in the whole plant, but also the necessary measures to ensure the safe production of the power grid.
