直流功率传输模式是直流输电的核心参数之一。天广直流输电系统功率传输模式包括单极功率模式、单极电流模式和双极功率模式。对这三种功率传输模式进行了对比分析,并重点讨论了其相互间的转换条件。结合一个参数设置不当导致的系统异常的案例,分析了功率模式转换设置条件对系统的影响,并对相关的设计逻辑提出了改进建议。

The DC power mode is one of the most important parameters for HVDC transmission systems.For the control system of Tianshengqiao-Guangzhou HVDC project,there are three DC power transmission modes,namely the monopolar power mode,monopolar current mode and bipolar power mode.These modes are analyzed in this paper in comparison with each other,especially their exchange conditions from one to another.Taking a case of incorrect parameter setting as an example,the paper analyzes the influence of the exchang condition setting on the system,resulting in suggestions for related logic improvement.
