双电站船舶选择性保护设计

摘要

With the growing complexity of shipboard equipments on naval warships ,capacity of power load is also increasing,resulting in increasing the power distribution level of electric power system. Double electric power systems are also more widely applied on the warships and passenger ships demanding safe return capability. This paper introduces the reasonable distribution of protection setting value among the crossbar switch of double electric power systems,bus tie switch of main distribution board and switches of each level of electric distribution systems,and also matching principle of each switch.%随着海军舰船的舰载设备日趋复杂以及负载容量越来越大，导致电力系统配电层次日益增加，双电站也更广泛地用于舰船以及要求具备安全返港能力的客船上。文中介绍双电站之间的跨接开关、主配电板的母联开关与配电系统各层次开关间保护整定值的合理分配以及各层开关的匹配原则。
