摘要
串联式混合动力系统船舶是指船舶推进器的直接驱动力只来源于电动机的混合动力船舶[1],船舶主动力可采用两种及以上的电力能源装置,通过配电系统实现电能的混合调度。本文以一艘采用超级电容储能装置的串联式混合动力系统的近海轮渡为背景,分析本船系统中直流母排系统短路故障选择性保护设计的原理,仿真以及实际短路电流测试结果。研究结果可以为后续类似船舶动力系统提供选择性保护设计参考。
Series hybrid power system ship refers to a hybrid ship in which direct drive force of ship propeller only comes from the electric motor[1].The main power of the ship can adopt two or more electric energy devices to realize the hybrid power dispatching through the power distribution system.Based on a series hybrid system offshore ferry with super capacitor as energy storage device,this paper analyzes the design principle,simulation and actual short-circuit current test results of selective protection of DC busbar system short-circuit faults of the ship.The study results can provide a reference for selective protection design of subsequent similar marine power systems.
