摘　　要：阐述了一种基于电力系统仿真软件PSS/E求解静态电压稳定裕度的方法。该法通过PSS/E提供的函数模块,采用内嵌的PYTHON语言进行编程。由于包含了对3绕组变压器和潮流初值回存的处理语句,使其能应用于大规模电网静态电压稳定裕度的求解。几个IEEE标准算例和一个大型电网静态电压稳定裕度的求解验证了所提方法的有效性和可行性。A method based on electric power system simulation software PSS/E for determining the static voltage stability margin is illuminated, which uses the function sets provided by PSS/E and the programming language PYTHON embedded in PSS/E. The method can be applied to the solution of static voltage stability margin of large scale power systems since it contains the processing programs for three-winding transformers and the initial value of the power flow equation. Several standard IEEE study cases and a large scale grid case prove the method effective and feasible.
