摘　　要：阀控系统作为直流输电控制保护系统与换流阀之间的接口设备,对直流系统的稳定可靠运行起着重要作用。因此提高阀控系统的可靠性是设计阀控系统时要达到的首要目标。在介绍H400换流阀阀控系统组成结构和基本功能的基础上,详细介绍了H400换流阀阀控系统特有的高可靠性串行通信方式,并阐述了此种串行通信方式的实现方式和特点。这种通信方式已在宁东—山东±660 kV直流输电工程中成功应用,并取得了良好的效果。As the interface device between the control-protection system of DC transmission and converter valve, valve control system plays an important part in the reliability of HVDC system. So the reliability improvement of valve control system is the first purpose in the system design. Based on the introduction of the composition structure and basic function of H400 valve control system, the unique serial communication mode with high reliability in this system was introduced in detail, as well as its realization way and characteristics. This communication mode has been successfully applied in Ningdong-Shandong ＋ 660 kV DC transmission project, which has achieved good results.
