摘　　要：云广直流总线系统分为4个独立的部分:控制总线,现场总线,TDM总线和MPI总线。由于控制总线与TDM总线都是初次使用于特高压直流输电系统中,缺少运行维护经验,TDM总线异常已造成云广直流停运事故。介绍了总线系统各部分的配置、工作方式和通信方式,分析各部分总线故障可能引起的总线系统运行风险。通过研究在云广直流极Ⅱ调试和试运行过程中几次总线系统运行事故,提出了相应的改进建议,为特高压系统的设计、运行和维护提供参考。The bus system of Yunnan – Guangdong ±800 kV DC transmission system consist of control bus,field bus,TDM bus and MPI bus.As the control bus and TDM bus are first used in the UHVDC transmission system,lacking of experience in operation and maintenance,outage incidents of the DC system have happened due to the TDM bus fault.In this paper,the cofiguration,operation and communication of all buses are introduced,and the operation risks caused by each bus failure are analyzed.Based on the research of the bus failures in the test of pole Ⅱ and commission operatio n of the DC system,certain proposals for the improvement of bus system are given,which can be taken as reference for the design,operation and maintenance of UHVDC transmission systems.
