摘　　要：分析了传统船舶直流电力系统保护的缺陷,通过仿真计算得到了混合型限流熔断器的短路限流值,提出了基于混合型限流熔断器短路限流特性的船舶直流电力系统选择性保护方法,研究结果表明采用混合型限流熔断器后电力系统保护选择性与速动性都能得到保证,有效提高了船舶直流电力系统的安全水平。The shortcoming of traditional shipboard DC power system protection is pointed out, the short circuit current limiting value of hybrid current limiting fuse is got by simulation calculation, and the selectivity protection method based on short circuit current limiting character of hybrid current limiting fuse is proposed The study result shows that selectivity and rapidity of power system protection can be uniformed using hybrid current limiting fuse, which can benefit security of shipboard DC power system.
