|
摘要
混合多端直流输电具有较好的工程应用前景,目前对于混合多端直流线路保护的研究主要集中在原理与算法方面,缺乏对保护配置方案进行系统的研究。该文在PSCAD上搭建了混合多端直流输电典型拓扑结构仿真模型,分析了混合多端直流输电线路保护技术难点,研究了混合多端直流线路故障特征,在此基础上提出了直流线路保护的配置方案及直流断路器重合闸策略,具有一定的工程应用价值。
Hybrid multi-terminal HVDC transmission has better engineering application prospects. At present, the research of hybrid multi-terminal HVDC line protection mainly focuses on principle and algorithm, and lacks systematic research on protection configuration scheme. In this paper, a typical hybrid multi-terminal HVDC transmission topology simulation model is built on PSCAD, and the technological difficulties in the hybrid multi-terminal HVDC transmission line protection are analyzed. The characteristics of the hybrid multi-terminal HVDC line fault are studied. On this basis, the configuration scheme of the HVDC line protection and the reclosing strategy of DC circuit breaker are proposed. It has engineering application value.
