摘要/Abstract

摘要： 直流区域配电网是交直流混联型电力系统的重要中间网络,对全船电能的分配优化和提高船舶生命力具有重要意义。该文对典型的船舶直流区域配电网的拓扑结构进行分析,并根据其运行特点,研究了各类常用的直流线路保护方法的适用性,得出各类保护的优缺点,获得电流差动保护、电流变化率与电流变化量相结合的电流突变量保护对船舶直流区域配电网有着较好适应性的结论,为船舶直流区域配电网的保护方案的研究奠定理论基础。

关键词: 船舶直流区域配电网, 电流差动保护, 电流变化率, 电流变化量

Abstract: Direct current (DC) regional distribution network is the important intermediate network of AC/DC hybrid power system. It is of great significance to optimize the distribution of electric energy and improve the vitality of the ship. This article analyzes the topological structure of the typical ship DC regional distribution network, and studies the applicability of the various commonly used DC line protection methods according to their operation characteristics. It also summarizes the advantages and disadvantages of the various protection methods. It is concluded that the protection of the abrupt change current, which combines the current differential protection, the current change rate and the current change amount, has the better applicability to the ship DC regional distribution network. It provides theoretical foundation for the research on the protection methods of the ship DC regional distribution network.

Key words: ship direct current (DC) regional distribution network, current differential protection, current rate of change, current variation
