摘要：
Aimed to solve the problem-power system low frequency oscillation in area main lines, this paper presents a decomposition of power system low frequency oscillation which can monitor vibration modal parameters quickly and accurately:The core of low frequency oscillation monitor is an improved Hilbert-Huang Transform(HHT) algorithm through the online record data superposition integral cycle cosine both ends of the signal, signal preprocessing is the extreme point. The method has solved the EMD decomposition process of "end effect" problem; Through the MATLAB simulation verifies the effectiveness of the proposed method.
