Research results show that when the output of voltage regulator is the maximum value, the voltagetransient stability margin of power system does not achieve its maximum;
仿真结果表明，当电压调节器的输出电压为最大值时，系统电压暂态稳定裕度没有达到最大；

If a step voltage is applied to the circuit, a transient current is generated.
如果将一个阶跃电压施加到电路，会产生一个瞬态电流。

NOTE 3 When deducing the working voltage, the effect of transient voltages is ignored.
