摘　　要：针对高压直流输电线路保护的特点,较全面的概述了直流线路故障特征以及直流线路故障的配置原理和直流线路保护动作顺序,比较分析了ABB公司和Siemens公司的行波保护判据,结合天广直流输电工程,采用MATLAB对天广直流输电工程中Siemens公司的行波保护进行仿真分析。Based on the characteristics of line protection of HVDC power transmission, the paper describes the characteristics and disposition principles of DC line fault as well as the action sequence of DC line protection. A comparative analysis on the traveling wave protection criteria of ABB and Siemens is done. Taking Tianshengqiao-Guangzhou HVDC transmission project as an example, the DC line protection of Siemens company in Tianshengqiao-Guangzhou HVDC transmission project is simulated on MATLAB.
