摘要:
      直流配电系统中电力电子装置众多。一方面,电力电子装置的脆弱性提高了对保护的要求;另一方面,依靠灵活可控的电力电子装置,通过直流配电系统控制与保护协同实现故障快速恢复成为直流配电系统控制与保护研究的重要思路。文中首先归纳了直流配电系统保护与控制协同的整体思路;其次总结了换流阀子模块结构和控制策略对直流配电系统故障特性的影响,归纳了基于保护与控制协同思想的直流配电系统保护原理,分析了其协同配合过程;最后,对直流配电系统控制与保护协同研究进行了总结和展望。
Abstract:
      In DC distribution system, large number of power electronic devices increases the difficulty of DC protection for their vulnerability. However, based on the flexible and controllable power electronic devices, realizing quick recovery of fault by coordinated control and protection becomes an important idea in the research of DC distribution system. Firstly, the overall thought of coordinated control and protection in DC distribution system is summarized. Secondly, the influence of the structure and control strategy of sub-modules of converters on the fault characteristics in DC distribution system is analyzed. The protection principle of DC distribution system based on the idea of control and protection coordination is summarized, and the coordination process of control and protection in DC distribution system is analyzed. Finally, the research on the coordination of control and protection of the DC distribution system is summarized and prospected.
