摘　　要：随着极址资源的日益稀缺,多回直流系统共用接地极设计成为直流系统接地极设计的发展趋势。介绍了金沙江水电外送特高压直流系统共用接地极设计的原则、技术要求,总结了其接地极设计方案,重点介绍了电极布置方案及导流系统设计。With gradual lack of pole site resources the common ground pole design of multi-circuit DC system has become the developing trend of DC system ground pole design. The paper introduces the design principle, technical requirements for Jinshajiang River hydraulic power outgoing UHVCDC transmission system common ground pole, sums up its design scheme, and lays special stress on pole arranging option and diversion system design.
