摘　　要：概括电力系统静态电压稳定分析方法,对现有的静态电压稳定性指标进行分析和总结。基于仿真软件PSS/E(thePower System Simulator for Engineering)和PSASP(电力系统分析综合程序),提出分别根据灵敏度指标和节点参与因子指标确定静态电压稳定薄弱区域的方法。运用这两种方法,对EPRI-36节点系统进行静态电压稳定分析,确定系统的薄弱节点和薄弱区域,仿真结果表明了这两种方法的有效性。这两种方法计算简单、准确度较高,特别是前一种方法对大型互联电网具有良好的适应性。Static voltage stability analysis methods and indexes are summarized. Based on simulation software PSS/E and PSASP, two methods which can find the weak area of static voltage stability are proposed by using sensitivity index and node participant factor index separately. The EPRI-36 nodes system is Jaken as an example to find its weak node and area by using proposed methods. Simulation results show that two methods are simple, precise and effective, and the first method is especially suitable for the analysis of large interconnect power grid.
