摘　　要：在三峡电厂厂用交流电源全部消失、机组全部停机、外部电网大停电时,电厂可利用三峡电源电站机组具备黑启动功能这一特点,迅速启动电源电站机组,恢复对泄洪闸的供电,保证大坝的安全;给三峡左、右岸电站提供厂用电,恢复三峡电厂的运行,从而恢复对外部电网的供电。文中分析了三峡电源电站机组黑启动的功能及特点,并对黑启动的流程及黑启动成功后对全厂和外部电网的恢复过程进行了分析,提出了合理的恢复电源的步骤,并分析了影响机组黑启动的关键因素。Through the black start function of the units of the power service station of the Three Gorges Hydropower Plant （TGHP）, the units can be quickly started and the power supply for the flood gates can be restored when the AC auxiliary power supply of the TGHP disappears, all the units are shut down and external power network fails. So the power supply for the left station and right station can be restored, the safe operation of the dam and the plant is ensured. The black start control function and its characteristics of the units of the power service station are analyzed, and the recovery process of the power system of the whole plant and external power network after black start succeeds is analyzed, too. Finally, the key factors influencing the black start are analyzed, and the reasonable step for the recovery of power supply is put forward.
