Abstract

Wide-area monitoring systems (WAMS) are spread in many power systems around the world, which demonstrate their significance and potential for power system operators. Thus, this paper emphasizes the use of synchronized-measurements-driven applications in power systems. To this end, two Matlab-embedded applications are developed using the graphical user interface (GUI) environment of Matlab. The former provides synchrophasor estimates that are processed and stored by means of a phasor estimation algorithm and a database, respectively; meanwhile the latter consists of a power system modal monitor application that is able to capture the modal information corresponding to low frequency oscillations (LFOs) in power systems. Also, the DIgSILENT PowerFactory environment is employed for running EMT simulations, whose results provide instantaneous signals to the phasor estimation stage in Matlab. Finally, results exhibit a WAMS simulator dealing with a LFO captured by PMUs, showing the performance of three traditional technique for identifyina electromechanical modes in power systems.

基于Matlab和powerfactory的WAMS模拟器

广域监控系统(WAMS)在世界各地的电力系统中得到广泛应用，显示出其对电力系统运营商的重要性和潜力。因此，本文强调了同步测量驱动在电力系统中的应用。为此，利用Matlab的图形用户界面(GUI)环境开发了两个嵌入式Matlab应用程序。前者提供同步相量估计，同步相量估计分别通过相量估计算法和数据库进行处理和存储;后者包括一个电力系统模态监测应用程序，该应用程序能够捕获电力系统中低频振荡(LFOs)所对应的模态信息。此外，还利用DIgSILENT PowerFactory环境运行EMT仿真，仿真结果为Matlab中的相量估计阶段提供了瞬时信号。最后，研究结果展示了一个处理pmu捕获的LFO的WAMS模拟器，展示了三种传统技术在电力系统中识别机电模式的性能。
