摘　　要：在锦屏—苏南、向家坝—上海特高压直流输电工程中直流保护和控制系统采用DCC800硬件平台,直流保护与控制系统通过eTDM总线完成数据交换,包括所有的保护动作信号。对直流保护和控制系统的配合逻辑进行了详细的阐述和研究,包括直流保护与控制的硬件组成,直流保护与控制系统间的信号交换,直流控制系统对保护信号的处理,以及控制系统软件中"三取二"选择逻辑、保护矩阵的配置以及不同类型的动作响应等;此外,对DCC800与西门子技术的控制保护系统进行了比较分析。根据工程实际运行状况来看,采用该设计理念的直流控制和保护系统运行稳定、可靠。DCC800 control and protection hardware are used in Jinping-Sunan and Xiangjiaba-Shanghai UHVDC project. The signals include all the protection actions are transferred from DC protection to control systems via eTDM Bus. The cooperation of DC control and protection systems is described and analyzed in detail, include the hardware configuration, the communication between protection and control systems, the realization theory of two of three logic and protection action matrix in the DC control software, the difference is compared between DCC800 and Siemens technology. According to the actual running situation of the project, the DC control and protection system can work stable and reliable.
