Abstract： During the debugging process of a certain ship’s generator set， there was an occasional abnormal tripping phenomenon of the main circuit breaker during the synchronous grid connection of the genetator set. Based on the instantaneous tripping phenomenon of the main circuit breaker of a ship’s generator set during parallel operation， this article elaborates on the fault analysis， trouble shooting and fault handling plan， and summarizes the experience gained during this fault trouble shooting process.

Key words： generator grid connection;  instantaneous disconnection;  circuit breaker

船舶用电设备繁多，船舶电站作为一种孤岛型电站，受空间及发电机单机容量限制，满足大功率船舶用电需求时均需要安装多台发电机组，且发电机组在网数量也随着船舶电网负荷的变化而随之改变。（剩余4518字）
