Abstract

Prony analysis and matrix pencil method have been widely used for monitoring power system oscillations. In this paper, a performance study has been made on Prony analysis and matrix pencil method, which utilize single signal, as well as multiple signals, to estimate the dominant modes of oscillations. The performance of the two methods are evaluated on actual data obtained from PMUs interfaced to a real time power system simulator, in which test systems are simulated including the complete dynamical models of the equipment. The widely used WSCC 9-bus system, the 2-area 11-bus system, and the New England 39-bus system are taken as the test beds for the study.
比较proony分析法和矩阵笔法监测电力系统振荡的性能
proony分析法和矩阵笔法在电力系统振荡监测中得到了广泛的应用。本文对利用单信号和多信号估计主振型的proony分析和矩阵铅笔法进行了性能研究。通过与实时电力系统模拟器接口的pmu获得的实际数据,对两种方法的性能进行了评估,并对测试系统进行了仿真,包括设备的完整动力学模型。以广泛使用的WSCC 9-bus系统、2区11-bus系统和新英格兰39-bus系统作为研究的试验台。
