摘　　要：电力系统短路电流计算值是选择电气元件短路承受能力、开关分断能力及校验电气元件动稳定、热稳定的基本依据,也是作为电力系统继电保护整定值的主要依据。因此,电力系统短路电流的计算,在电气元件选型和系统设计过程中更为重要。The calculated value of power system short circuit current is the basis of selecting short circuit affordabili-ty and switch breaking capacity of the electrical components,and verifying the dynamic stability and thermal stability of the electrical components,and also it is the main basis of the setting value of power system relay protection.The calcu-lation of power system short circuit current is very important in the selection of electrical components and system de-sign.
