摘要
大规模海上风电场采用直流联网构成多端直流网络是沿海风力发电的发展趋势,在介绍了已投运的多端直流输电工程概况的基础上,分析了传统以及新型多端直流输电系统的构成原理和运行方式,引入了基于握手理论的多端直流网络故障检测原理,并指出了其限制因素。
It is a trend to adopt the multi-terminal DC system （MTDC） to connect large scale off-shore wind farms. In this paper, the basic principles and operational characteristics of conventional MTDC and voltage source converter （VSC） MTDC were analyzed based on the general situation of commissioned MTDC projects. The handshaking theory used for MTDC fault detection was presented, and the restrictive factors for MTDC development and application were pointed out.
