摘要:舰船供电系统的生命力必须和舰船总体的抗沉性能相适应,当舰船遭受战斗损害而保持不沉时,电站和配电系统的剩余供电能力必须保证维持舰船机动性、生命力和最低限度自卫能力所必须的重要负载的供电。本文通过对某型舰船供电系统失电恢复试验时出现的问题进行分析,在不改变系统原理的基础上,提出系统的优化改进方案,并在实船试验中验证了其有效性。

Abstract: The vitality of the warship power system must be consistent with the unsinkability of the warship. When the ship suffers combat damage and remains unsinkable, the residual power supply capacity of the power station and distribution system must supply the vital loads necessary to maintain the warship's maneuverability, necessary ship vitality and minimum self-defense capability. Based on the analysis of a problem in the power loss recovery test of a certain type of warship, this paper proposes an optimization and improvement scheme with simplified system judgment logic on the basis of not changing the system principle, and verifies its effectiveness in the real ship test.

1 某型舰电力系统组成
基于电力系统冗余设计理念和合理布置要求,某型舰电站一次网络系统由三段主配电板各搭载两台柴油发电机组组成。每段主配电板均可单独形成电站,为该型舰提供正常航行所需的供电,并在紧急情况下通过事故电力网系统对全船重要负载提供供电。
三段配电板由布置在两舷的舷侧配电板相互连接,通过调整舷侧跨接开关或主配电板跨接开关的分断或闭合,可对电网进行分区供电或联网供电;电站控制系统对各个跨接开关的通断状态进行判断,在确保供电系统正常的情况下,同时避免形成环网。
每段主配電板可通过母联开关的分断,来满足人员进行配电板的检修、维护等操作;三段主配电板均与岸电开关相连接,可通过任一电站的岸电开关对舰船进行供电,确保停泊状态的用电需求;除主电网外,还搭载了一定容量的UPS系统,作为全船应急电源使用。……
