Abstract:

同步相量测量单元(phasormeasurementunit,PMU)的本质特征是同步量测,因此卫星同步授时信息的准确程度将直接影响PMU量测的精度和可靠性,从而进一步影响电力系统动态过程监测等基于PMU量测的各类应用功能的发挥。文章针对我国安装于变电站和发电厂的2类PMU分别展开讨论,重点推导了电力系统动态情况下考虑授时偏差的变电站PMU量测相量计算公式,分析了授时偏差对相量幅值与相角量测的影响规律;此外,根据发电厂PMU量测发电机转子角原理,分析了电力系统稳态及动态情况下发电厂PMU实测发电机转子角与授时偏差的关系。最后,通过搭建的物理实验平台,进行了稳态和动态实验,验证了理论分析的正确性。
