同步相量测量提供高分辨率、时间同步数据，揭示大范围电力系统的复杂动态。该技术能够从系统的任何部分收集亚秒级数据，并具有实时监控整个互连的能力。利用该技术，在实时动态监测系统平台中开发了在线孤岛检测应用程序。孤岛检测应用利用频率信号和/或电压角度信号作为输入来跟踪PMU之间的频率差和/或角度差的变化。通过仿真算例对应用程序进行了测试，结果表明该方法能够正确检测孤岛情况。该应用程序可以帮助电力系统运营商监控、分析孤岛状况并采取纠正措施。
Synchrophasor measurements provide highresolution, time-synchronized data, which exposes the complex dynamics of the power systems across wide areas. This technology enables collection of sub-second data from any part of the system the capability of real time monitoring of an entire interconnection. Taking advantage of this technology, an on-line islanding detection application has been developed in the RealTime Dynamics Monitoring System Platform. The islanding detection application utilizes frequency signals and/or voltage angle signals as input to track frequency differences among PMUs and/or changes of angle differences. A simulation example is used to test the application, and the result shows that it correctly detects the islanding condition. This application can help power system operators monitor, analyze and take corrective actions for islanding conditions.
