摘要
介绍了特高压直流输电工程交流滤波器保护系统的发展,结合溪浙工程特高压直流输电交流滤波器的特点及工程现场实际运行需求,针对交流滤波器小组光电流互感器的硬件特性,通过许继自主开发的软件平台,设计交流滤波器小组检修功能。阐述交流滤波器大组集中化配置中小组光电流互感器故障时,检修功能的实现方法。交流滤波器小组检修功能,对于大负荷运行的特高压直流系统十分必要,可增强系统的可靠性。
The development of AC filter protection system in ultra-high voltage direct current( UHVDC) is described in this paper based on the characteristics of UHVDC transmission AC filter and actual requirement of project field. For the AC filter sub-bank hardware features of optical current transformer,by applying the Xuji self-developed software platform,AC filter sub-bank maintenance function is designed. When the AC filter bank of centralized configuration,sub-bank of optical current transformer fault,the realization method of the maintenance function are expounded. AC filter sub-bank maintenance function is very necessary for large load operation of UHVDC system,it enhances the reliability of the system.
