摘　　要：介绍一种新型的电力系统动态监测装置及其动态模拟试验结果。该装置以ＧＰＳ（全球卫星定位系统）提供的高精度时间为基础构造系统的同步基准相量实现被测交流量的相量形式测量，采用可灵活配置的监测程序实现电力系统中各种监测要求，并提供了通过广域网互联形成全网同步监测系统的接口。在动模实验室中构造了３机９节点的实验系统对装置功能进行了全面的测试，给出了不同地点不同故障下所记录的电压、频率及相角的动态过程及分析，包括一次完整的失步、振荡和再同步过程。? A new power system dynamic monitoring unit and its experimental results in the field test have been introduced. The unit measures the AC quantity in phasor form relative to a uniform reference phasor created on the basis of accurate time provided by GPS(global positioning system). The unit can be configured flexibly to meet different demands on the power system monitoring. A network interface makes it possible to form a global network synchronized monitoring system. A 3 machine and 9 bus system has been constructed in the lab to test the device. The recorded dynamics of voltages, frequencies and phase angles, including one full process of unsynchronizing, oscillation, and re synchronizing are given and analyzed. 
