摘　　要：短路电流IEC算法目前在国际上广泛运用,而国内民用建筑电气设计领域在计算低压网络最大短路电流时普遍采用实用算法。通过算法介绍、计算过程以及实际计算数据,比较了两种方法的区别,为民用建筑电气设计中低压网络短路电流计算方法的选择和应用提供参考。The IEC algorithm of short circuit current is widely used in the world at present,while the practical algorithm is generally used in the domestic civil building electrical design field when calculating the maximum short circuit current of low voltage network.Through the algorithm introduction,calculation process and actual calculation data,the two algorithms were compared.It provides reference for the selection and application of the calculation method of short circuit current of low voltage network in the civil building electrical design.
