摘要
以云广特高压直流工程直流测量系统多次发生故障为背景,介绍了云广特高压直流测量系统组成及直流测量时分复用总线运行逻辑。通过仿真和试验,深入分析了造成直流测量系统受干扰的原因及当前直流测量系统抗干扰措施存在的问题,给出了相应解决方案并予以实施。解决方案经实际故障验证了其正确性,提高了云广特高压直流的运行可靠性,同时也为今后直流输电工程的抗干扰设计提供了有益参考。
Based on the faults occurred in measurement system of Yunnan-Guangdong ultra-high-voltage direct current （UHVDC） transmission for many times, composition of Yunnan-Guangdong UHVDC measurement system and the operation logic for time division multiplexing （TDM） bus are introduced. Through the simulation and experiment, the cause suffering from electromagnetic interference （EMI） and the problems existed in anti-EMI measures of I）C measurement systems are analyzed deeply. The corresponding solution scheme is given and implemented. Correctness of the solution scheme is verified by the actual fault. Solution scheme can not only enhance the operational reliability of Yunnan-Guangdong UHVDC operation, but also benefit to the anti-EMI design of DC project.
