摘　　要：提出了应用PSS/E潮流和动态仿真模块分析电力系统电压稳定的方法。利用PSS/E中的潮流计算模块,能有效判断系统电压是否稳定,并求出系统电压稳定裕度及影响电压稳定的弱节点、弱支路和弱区域;利用PSS/E软件的状态空间仿真模块和扩展时段仿真模块,可对电力系统进行动态仿真,找出影响系统电压稳定的关键因素。最后以一大型电网为例,分析计算说明该软件在电力系统电压稳定性方面的应用情况。A method of using PSS / E's power flow and dynamic simulation modules to analyze power system voltage stability is presented. The power flow calculation module is used to estimate the power system voltage stability,to calculate the stability margin and to find out the weak voltage stability buses,lines and zones. The state-space simulation module and the extended term simulation module are applied in power system voltage stability dynamic simulation to find out the key factors affecting voltage stability. Calculation of a large power system shows the application of PSS / E in power system voltage stability analysis.
