The multi-terminal DC( M TDC) has the advantages of DC interconnection,multiple pow er supply and multiple load placement,w hich is the development direction of DC transmission technology. As an important restricting factor,the control and protection technology for M TDC has being paid more and more attention. Based on the commonly used parallel connection for M TDC,the applicability of the tw o-terminal DC line protection principle for M TDC w as analyzed. According to the topological structure characteris...
