摘要
基于同步相量测量技术的电网实时动态监测系统能在线监测系统动态过程的全貌,同时,其记录的电网扰动事件数据有助于对仿真系统的模型与参数进行离线校核。文章结合华北电网实时动态监测系统的研制,论述了该系统的构成、主要功能和特点。该系统一期工程由华北网调主站系统和安装在7个关键发电厂和变电站的子站装置构成,子站与主站之间通过调度数据网连接。文章结合东北500kV系统三相短路大扰动试验介绍了该系统在华北电网中的实际应用情况。
The full view of power system dynamic processes can be supervised by wide-area real time dynamic monitoring system (WAMS) based on synchronous phasor measurement (SPM) technology. Meanwhile, the recorded data of the power system disturbance accidents is helpful to the off-line verification of the model and parameters of simulation system. Based on the development of real-time dynamic monitoring system for North China Power Grid, the architecture, main functions and features of the monitoring system are described in detail. The first stage of this monitoring system consists of the master-station located at the dispatching center of North China Power Grid and the sub-stations installed in seven key power plants and substations; the connection among the sub-stations is implemented by dispatching data network. The practical application of this WAMS in North China Power Grid is presented through the artificial large disturbance test for three-phase short circuit occurred in Northeast China Power Grid.
