摘要
对在西北电网750kV变电站装设的PMU装置应用和运行情况进行了阐述。西北电PMU相量测量装置具备实时监测、动态数据实时记录和实时通信三大功能．且三者互不干扰、互不影响。列举了该装置在满负荷试验和电网故障时的应用实例．对运行中发现的端子接线问题、程序参数设计问题进行了具体分析。通过对广域相量测量的总结说明在750kV电网范围内推广开展的重要性。
The application and running status of phasor measurement unit in 750 kV substation are introduced. Its three main functions are real-time monitoring, data recording and communicating, and there is no interference or interaction among them. The practical application examples of this unit in full-load test and power grid fault are presented, and the terminal connection and program parameter design are analyzed in detail. The summarization indicates the significance of PMU installed in 750 kV grid project.
