基于Prony算法的次同步谐振检测方法
New Method for Detection of Sub-synchronous Resonance Based on Prony Algorithm
摘要
Abstract
A new method based on Prony algorithm for detection of sub-synchronous resonance (SSR) is proposed. Based on the electrical measurement, the current which is most likely to get is selected as the sub-synchronous resonance detected amount. First, the noise of the sampled current signal is filtered, and then the amplitude of the signal in resonant frequency is identified and analyzed by using Prony algorithm. After that, whether sub-synchronous resonance occurs or not is determined by observing the changes of the amplitude in a continuous time period. In addition, the specific steps of Prony algorithm for implementing, treatment of noise and Prony algorithm's performance advantages for detection of SSR are given. Finally, the simulation is done on IEEE first benchmark system model for sub-synchronous resonance, and the results illustrate the effectiveness of the presented approach.关键词
