| 摘 要： | 对配电变电站的电压稳定性原理进行仿真,分析表明,在负荷有功一定的情况下,负荷功率因数的下降对电压稳定性将会产生两个方面的影响:负荷无功-电压特性曲线上升,与之相对应的电网无功-电压特性曲线下降,从而使配电变电站的电压稳定性显著下降。

| Abstract: | The voltage stability theory of distribution substation is simulated.The results show that under certain load active power,power factor decreasing has two effects： load reactive-voltage characteristic curve rise corresponding to power network reactive-voltage characteristic drop;the voltage stability of distribution substation decreased significantly. |
