中文摘要: 简要介绍了短路电流计算曲线的制作方法和使用原理,采用解析法在一定条件下对任意时刻短路电流周期分量进行计算,通过将此计算结果与典型短路电流计算曲线的对比分析,得出了汽轮发电机容量越大,典型短路电流有效性越差的结论.最后提出了计算曲线法的改进方法.
Abstract:The way to work out and use the power system short-circuit current curve is reviewed briefly at first.Then the symmetrical component of short-circuit current of any instant is calculated with function rules in the cases of three types of large-capacity turbine generators.The calculation result is compared with the standard short-circuit current curve,which leads to the conclusion that the larger the generator capacity,the less valid the typical short-circuit current is.Finally,the way to improve the traditional short-circuit current is proposed.
