摘　　要：介绍了现阶段高压直流输电系统中主要采用的两种换流阀技术路线,分析了换流阀与控制保护系统的信号接口类型。针对伊克昭换流站与中州换流站所选用的4种不同换流阀与直流控制保护系统接口的设计和实现方法,对比分析了各直流控制系统与阀基电子设备间的信号类型、信号实现方式,包括光控制信号、电气开关量信号等,并为新工程建设与运维提出合理化建议。This paper introduces two main technical routes of converter valve used in high voltage direct current(HVDC)transmission system,and analyzes the signal interface types between converter valve and control and protection system.Aiming at the design and implementation methods of four different converter valves and DC control and protection system interfaces selected by Yikezhao converter station and Zhongzhou converter station,the signal types and signal implementing modes of various DC control systems and the valve-based electronic equipment are compared and analyzed.The signal implementing modes include optical control signals,electrical switch signals,etc.,and this paper puts forward reasonable suggestions for new project construction and operation.
