摘要 为了使电网的短路电流计算和开关开断能力校核能有一个科学合理的依据,降低对开关设备的遮断能力要求在分析IEC 909标准、ANSI标准及暂态稳定计算短路电流方法的基础上,提出了以暂态电抗Xd忆作为电机参数进行短路电流工程计算方法,并以PSCAD/EMTDC搭建IEEE 9的动态仿真模型,以动态仿真结果为基准,给出了2个标准的精确度,把提出的短路电流计算方法与根据IEC 909标准、ANSI标准及机电暂态仿真计算的结果进行了比较分析,结果显示基于暂态电抗Xd忆短路电流计算方法具有较好的精确性,且可以明显降低电网短路电流评估计算值。 To select cireuit breakers with a more scientific and more rational way, this paper presents a new method of the short circuit calculation based on transient reactance. With the result of the IEEE 9 dynamic simulation model built with PSCAD/EMTDC, the accuracy of the two standards are given and related calculations and comparative analyses are conducted accordingly. The results show that the proposed method is more accurate, and therefore has positive reference to the selection of circuit breakers.
