On-line Estimation of Low Frequency Osillation Mode Using Prony Analysis in the Power System

PRONY 해석을 사용한 전력계통 저주파 전동모드의 온라인 추정

This paper presents a mode estimation for the analysis of small signal stability in power system. The low frequency oscillation mode estimation is based on Prony method that is able to accurately compute the modal parameters (frequency and damping) of oscillation mode from time series. The time series or time domain data is obtained in TSA process. The method applied to a large scale power systems and compared on the eigenanalysis results.
