换流阀控制系统是直流输电系统的核心设备，主要起到触发、监视和保护换流阀的功能。以宁东—山东±660 kV直流输电工程为背景，阐述了换流阀控制系统的工作原理和设计特点，并对换流阀控制系统的现场运行情况进行了介绍，着重分析了调试及试运行期间阀基电子设备出现的问题，并提出了具体的解决措施和改进建议。

As the core equipment for HVDC transmission system, valve control system is mainly responsible for triggering, monitoring and protecting the converter valve. In Ningdong-Shandong ± 660 kV DC transmission project, the working principle and design features of the valve control system are presented. In addition, the on-site operation is introduced, with focus on the problems of valve base electronics(VBE) occurring in the commmissioning and trial operation. Finally, effective measures and improvement suggestions are proposed.
