摘要(Abstract)：

短路电流计算是电力系统和电气设备设计和运行中不可缺少的基本计算,对于大电网的短路计算,已有较为成功的计算方法和程序。但在实际工作中,仍有部分计算更适合采用手工方式。手工方式下进行网络化简存在速度慢、精确度低、容易出错的缺点。利用PSCAD进行网络化简,计算过程迅速、结果准确,能够显著提高工作效率。
Short circuit current calculation is indispensable to design and operation of power system and electrical equipment.For the short circuit calculation of large grid,there have been successful computing methods and procedures.In practical work,however,manual method is more suitable for some calculation.Simplifying network by manual method is characterized by it slowness,inferiority in accuracy and error-prone.The application of PSCAD in network simplification makes the calculation more rapid,more accurate,which can improve the work efficiency significantly.
