摘　　要：介绍了高压直流线路保护常见配置,分析了国内三大直流保护配置。天广直流投运初期行波保护动作频繁,经修改动作条件后,没有再发生误动和拒动。并提出了目前直流线路保护优化的建议。Common configuration schemes of DC line protection scheme are introduced. Protection schemes of three DC projects in our country are analyzed. Travelling wave protection in Tian-Guang HVDC system frequently mis-acted soon after put into operation. After a revision on action conditions, mis-action and refusion no longer occurred therefore. Suggestions for HVDC line protection scheme and optimization are proposed.

关 键 词：高压直流 故障 线路保护 优化
