在输电线路发生故障时，首先通过电功率平衡抑制各变量的剧烈波动；在此基础上再用汽门励磁协调控制器镇定系统。
When a transmission line fault occurs, the violent fluctuations of system variables are first suppressed with the aid of electric power equilibrium.
高压交流输电线路单位长度充电功率很大，由于空载长线电容效应将会引起很高的工频过电压。
Because of large capacitive charging of long ac transmission line, capacitance reaction of no loaded line will cause severe overvoltage.
