摘要
随着船舶供电网络结构复杂程度和选择性保护要求的提高,将纵差动保护应用于船舶电力系统有着越来越大的实际意义。它可对各种两端电缆及多引出线的母线短路故障进行有选择性的保护,同时,数字式纵差动保护也将为整个保护策略和后续供电控制提供了一个全新的实现方法。
With the improvement of marine power supply network and high requirement of the selective protection, longitudinal differential protection has more practical meaning in marine power system. It can supply selective protection to the short circuit fault of various 2-node lines or multi-node bus lines. And digital longitudinal differential protection gives a new realization to the whole protection strategy and the followed power supply control.
