摘要
对Prony和HHT这两种常用的基于量测信号的低频振荡模态参数辨识方法进行了对比研究。在介绍两种方法基本原理的基础上,分析了两种方法的差别。通过合成信号和实测信号的测试,对比了两种方法的性能和对各种信号的适应性。最后根据实验结果得出一些一般性的结论。
This paper compares between Prony and HHT,the two methods commonly applied to identify the low frequency oscillation modal parameters based on the measured signals.The basic principles of the two methods,as well as their differences,are described.Synthetic and measured signals have been tested in order to compare their performance and adaptability to various signals.Finally some general conclusions are drawn based on the test results.Prony;HHT;empirical mode decomposition;low frequency oscillation;oscillation mode;comparison
