| Abstract: | 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. |
