摘　　要：发生短路过电流电气故障时,为了能对电气末端设备进行保护,需要预估电气末端设备汇流排的短路电流。应用ETAP(电力电气分析、电能管理综合分析软件系统)通过不同电缆长度预估出上游短路电流贡献值,通过电机短路电流快速计算法预估出下游短路电流贡献值,汇总获得电气末端设备汇流排的短路电流。预估出的短路电流为电气末端设备选用合适的保护电器和汇流排等提供了依据。本预估方法适用于船舶及海洋平台等孤岛式电网具有一定的通用性及经济性。A electrical end-equipment to be protected when SC(short-circuit current) happened, a SC data to be estimated. The SC data to be combined upstream SC data estimated by different cable lengths based on ETAP(Electrical Transient Analysis Program) and downstream SC data of motor by Fast calculation. The estimated SC data provides the basis for the selection of suitable protective appliances and bus for the equipment. The method is suitable for off-grid power networks such as ships and offshore platforms, it has certain generality and economy.
