摘　　要：船舶电力系统短路电流计算是船舶电气设计中的关键。针对某海工船的多端母排电力系统进行研究和分析,基于ETAP软件对电网进行建模,并分析和计算了该电力系统的短路电流。根据短路计算结果,确定了主要保护开关的类型和整定值,对船舶多母排电力系统的设计提供了参考。The calculation of short-circuit current of ship power system is the key in ship electrical design.The multi-terminal busbar power system of an offshore rescue ship is studied and analyzed, the power grid is modeled based on ETAP software, and the short-circuit current of the power system is analyzed and calculated. According to the short-circuit calculation results, the types and setting values of the main protection breakers are determined, which provides a reference for the design of the ship’s multi-busbar power system.
