Analysis of Interarea Low Frequency Oscillations based on Mixed Method

摘要：

A novel strategy to study interarea low frequency oscillations for large scale power system is presented in this paper. Traditionally, eigenvalue method used to estimate the small signal stability of power system. With the rapid development of wide area measurement system, online identification is adopted to identify the oscillation modes of power system. The performance of these two methods is not perfect as they often used separately. Mixed analysis method takes advantages of both online identification and eigenvalue calculation method. It not only can identify dominant oscillation modes, but also calculate associated sensitivities and participation factors. The effectiveness of the proposed method has been demonstrated through the application of monitoring the interarea oscillations in Central China Power Grid.
