摘　　要：针对变电站电涌保护器(SPD)在线监测困难,现场测试成本过高,开发研制了一种SPD智能监测系统.首先介绍系统构架,对监测终端的设计、通信规约实现和中心管理平台的结构、功能和交互形式进行较为详细地阐述;研制了SPD智能监测系统,并在陈寮山微波站实际应用,证明了系统能够有效地采集雷击电流波形等参数,有效监测电涌保护器的运行情况;并根据保护器安装位置可以判断雷电流的入侵方式,为微波站整改防雷措施提供依据.Aiming at difficulties of online monitoring and high cost of field testing for substation SPD（surge protective device）,a SPD intelligent monitoring system was developed in this paper.The system architecture was introduced firstly.Four aspects including monitoring terminal design,communication protocol implementation and center management platform structure,monitoring system program were presented in detail.The SPD intelligent monitoring system was applied in Chenliaoshan microwave station,lightning current waveforms are effectively collected by the system,the real-time operation of SPD are recorded.Considering the location of SPD,the accurate invasion methods of lightning currents can be detected.It provides a theoretical foundation for the improvement of lightning protection in microwave station.
