摘　　要：介绍了上海电网电压稳定功率裕度指标,探索了电压稳定裕度指标的时域仿真校核方法。一系列基于PSASP的时域仿真校核表明,当系统运行在PV曲线的极限点时,电力系统可能体现出电压稳定和暂态功角稳定交互作用的特性。在极限运行点和其它的负荷水平下,仿真了电动机低压释放和低压减载对电压稳定的影响。　The power margin index for Shanghai grid voltage stability is presented,and the time domain simulation checking method for the power margin index is discussed.PSASP-based time domain simulations show that the power system may display the interaction of voltage stability and transient power angle stability when the system operates at the limitation points of the PV curve.The influences of low-voltage release and load-cutting of the generator on voltage stability were simulated under the conditions that the system operates at its limit points and under other loads.
