| Abstract: | Earth electrode faults occur in Yun-Guang,Tian-Guang,Gao-Zhao and Xing-An DC transmission lines of CSG and action strategy of unbalance protection of earth electrode are studied and improved many times.On the basis of introduction of action strategies of unbalance protection of earth electrode in four DC transmission systems,the paper comparatively analyzes similarities and differences among strategies of unbalance protection of earth electrode in each DC transmission system and it suggests that restart str... |
