摘　　要：对国华台电500kV升压站全站失压过程分析显示,由于保护装置难以感知系统运行状况,有必要采用安稳控制系统来判断系统运行状况,当升压站送出断面断开时,及时通过安稳装置出口动作于切机。It is shown by the analysis on the unit protection at the 500 kV Substation in Guohua Taishan Power Plant over losing power that as the relay protection equipments can＇t find the running condition of the power system, a safe-stability control system must be used to determine the running condition of the system, so that the turbine will be trip off when the substation losing connection with the power system.
