摘要
对国际大电网(CIGRE)会议的SC-B5专业委员会的研究领域、代表、工作组、年度会议安排等情况进行了介绍。2008年巴黎会议上,B5学术研讨会的主题有2个:过程总线(IEC 61850-9-2)对继电保护和变电站自动化系统的影响;继电保护和控制系统的生命周期管理。IEC 61850在变电站自动化系统站控层总线中的成功应用,鼓励人们更进一步思考互感器、断路器(隔离开关、接地开关)接口的数字化问题,也包括合并单元的配置问题,文章反映了这些方面的最新进展。数字化设备和系统的应用,一方面由于设备具有了强大的自检功能,可以有条件延长定期检验周期、简化检验项目,甚至取消定期检验;另一方面,不那么直观的数字信号、复杂的软件配置过程、频繁的设备更新换代也为维护带来了一定的挑战,需要另外设计新的试验和管理手段。
The scope, members, working groups and annual meeting arrangement of CIGRE SC-B5 are introduced first in this paper. On CIGRE Session 2008, two preferential subjects for B5 are:Impact of process-bus (IEC 61850-9-2) on protection and substation automation systems; Life cycle management of protection and control systems. Encouraged by successful application of IEC 61850 on station bus, people now research digitalized interface of instrument transformer, circuit breaker, isolator and earthing switch, and allocation of merging unit. The most recent development in these aspects is provided. The application of digital equipments and system brings about two consequences:on one hand, with the help of powerful self diagnose test ability of equipment, it is possible to prolong time interval of periodical test, reduce periodical test items, or even cancel periodical test totally; on the other hand, not so observable digital signal & more frequent upgrade of equipment also bring about challenges to maintenance.
