摘要
变电站的二次设备状态监测是实时监测继电保护等二次设备运行状况的重要手段,是变电站安全、稳定、可靠运行的重要保障。随着电网规模的发展,输电线路日趋复杂,继电保护装置也随之增多,需要监测的数据量、节点数量、通信通道量等大大增加,检修人员的工作量不断加大。智能变电站技术的发展,特别是二次状态监测技术和集中式保护装置的应用,有效的解决了这一问题。本文就智能变电站的二次设备状态监测技术进行研究,并提出解决方案。
Secondary equipments＇ condition-monitoring of substation is the important method to real-time monitor secondary equipments＇ running state e.g. relay protection, and is important indemnify of safety, steady, dependable of substation. Along with the development of power system＇s scale, transmission lines are gradually complicated, relay protection equipments are increasing with it, data volume, node, communication channels we need are greatly increased, overhauling people＇s work load constantly increasing. The development of smart substation, especially the application of condition-monitoring technology and centralized protection device can solve this problem effectively. This article carries on research secondary equipments＇ condition-monitoring technology in smart substation, and puts solution forward.
