摘要
金属氧化物避雷器(MOA)监测系统在智能变电站中得到越来越多的应用,但在工程运行中也存在一些问题,如运行不可靠、监测数据不准确、集成度差和系统故障率偏高等。为了解决上述问题,对智能型金属氧化物避雷器在线监测系统进行了改进设计,从系统整体构架、传感器设计、安装方式、在线监测智能电子设备(IED)设计等方面开展工作,提供了一种测量精度高、计算灵活、适应性及可扩展能力强的高可靠性避雷器在线监测系统方案,并全面支持基于光纤链路的通用面向对象变电站事件(GOOSE)、采样测量值(SMV)以及站控层制造报文规范(MMS)通信,可更好地满足智能变电站现场应用要求。
On-line monitoring system for MOA has been adopted in more and more applications in intelligent substations,but also encountered some problems during the application process,such as insufficient reliability , data accuracy,low integration and high rate of system failure. In order to solve the above mentioned problems,the design for the on-line monitoring system for MOA is improved. Integral structure,design of the sensor,installation method and the design of the intelligent electronic device are proposed, and a high measurement accuracy,flexible and adaptable on-line monitoring system for MOA with high reliability is provided, which also fully supports fiber-based GOOSE,SMV and station level MMS to better meet the application requirements in intelligent substations.
