摘要
变电站和电厂安装相量测量装置(phasor measurement unit,PMU)用于加强电力系统的动态检测和分析能力。但由于PMU相量测量装置对全球定位系统(global position system,GPS)的高度依赖以及对通道的严格要求,PMU装置故障频发。统计分析了PMU的常见故障,指出目前PMU故障包括了数据变量名称或系数错误、传输丢帧和离线文件召唤失败等情况,并针对各种情况给出解决意见。
Substations and power plants install the phasor measurement units （PMU） to strengthen dynamic stability detection and analysis ability on the power system. Due to its high reliance on global position system （GPS） and strict communication quality requirements, the PMUs entercounter frequent failure. Common failures of the PMU are given and discussed, including data variance name or coefficient error, flame lost, and non-real-time file transmission error. Solutions of these failures are given.
