摘　　要：基于直流主网的船舶电力系统,为保证供电可靠性,常使用整流发电机与蓄电池组直连的结构。由于船舶空间有限,发电机体积和功率受限,可能会出现船舶电力负载功率超过发电机的情况。本文提出一种并联供电控制策略,在负载功率不大于整流发电机额定功率时,可实现整流发电机恒压输出;在负载功率大于整流发电机额定功率时,可实现整流发电机和蓄电池组同时给负载供电,能够提升船舶电力系统的最大负载功率。In order to improve power supply reliability,rectifier generator and storage battery are always paralleled directly in the ship power system.Due to the limited space of the ship and the limited volume and power of the generator,the power load of the ship may exceed the power of the generator.This paper presents a parallel-power-supply control strategy,which can realize the constant voltage output of the rectifier generator,when the load power is not greater than the rated power of the rectifier generator.And the strategy can realize rectifier generator and storage battery supply power to load simultaneously,when load power is greater than rectifier generator rated power.The proposed control strategy can increase maximum load power of ship power system.
