摘　　要：随着电网负荷和系统规模的增加,导致短路电流水平快速上升,因此对电网进行短路电流计算分析具有重大的意义。介绍了电力系统综合分析程序PSASP短路计算模块的主要功能,应用PSASP对某省500kV及220kV厂站的短路水平进行了全面计算与分析,针对部分厂站短路电流水平超标问题,提出了相应的措施和建议。并对规划2010年电磁环网解环后,500kV/220kV厂站的短路电流水平进行计算分析,计算结果为电网的安全运行提供了可靠依据。With the increase of loads and components in power grid,the sharp increase of short circuit current will be induced. So it is very important to carry out the analysis of short circuit calculation. The primary function of PSASP short circuit calculation is introduced. The general calculation of 500kV and 220kV station′s short circuit current in some province are carried out by PSASP. Because some stations′ short circuit current exceed the standard, the corresponding measures and suggestions are proposed. Finally, an analysis of 500kV and 220kV station′s short circuit current is carried out after opening the electromagnetic loop in 2010. These conclusions can provide reliable basis for the safty operation of power grid.
