| 中文摘要 | 注意到换流站交流侧隔离开关和断路器操作会产生电磁骚扰,且最近该类骚扰源造成了多起直流闭锁事故。现场测量了开关操作产生的电磁骚扰,总结了骚扰源的基本特性,比较了不同类型开关操作产生的暂态过程的差异。采用实验的方法分析了不同的系统工作状态下的传播机理。分析了该类骚扰在二次系统中的分布以及时域和频域特性。基于离线实验分析了直流分流器的高频特性。; Noticing that transient EMI is generated by operating isolators and circuit-breakers in the AC side of HVDC converter stations, and resulting recently in several trips in several �00 kV HVDC converter stations, characteristics of transient electromagnetic interference due to different types of switching operations are summarized and compared based on onsite tests in a practical converter station. Measurements are performed to analyze the propagation mechanism of transient processes of various switching operations during different operation status. The EM noises generated by switching operations into secondary systems, especially the measuring system in DC side are analyzed as well. The high frequency characteristics of DC shunts, which is the most important path for EM noise propagating, is also analyzed based on tests. |
