摘要
短路电流计算结果对电网规划、电器设备选择、继电保护、电网安全稳定运行等有着重要参考价值。对比分析了不同短路电流计算标准中采用的不同计算条件,基于电力系统分析综合程序(PSASP)分析国标算法与E”=1算法主要区别,通过具体算例仿真分析影响两种方法计算结果差异的敏感性因素,为提高短路电流计算结果的精确度提供仿真技术支撑。
The calculation results of short circuit current offer important reference for power grid planning,electrical equipment selection,relay protection,and safe and stable operation of the power grid.In this paper the different calculation conditions used in different short circuit current calculation standards are compared.Based on the power system analysis integrated program(PSASP),the main difference between the national standard algorithm and the E"=1 algorithm and the sensitivity factors that affect the difference between the calculation results of the two methods are analyzed by the simulation analysis of specific examples,provide support for improving the accuracy of short circuit current calculation results.
