摘　　要：提出了一种基于实测的功角曲线检测区域间低频振荡模式的新方法,这种方法能有效检测出互联系统的区域间主导低频振荡模式,因此可以对扰动下的系统进行有效的分析。大系统算例结果表明,所提方法能准确的检测识别出系统主导区域间低频振荡模式,其结果与综合稳定程序(PSASP)计算出的结果一致,从而验证了所提新方法的正确性和有效性。Based on the measured power angle curve, a new method of detecting inter - regional low - frequency oscillation （LFO） mode is presented, it can effectively detect inter - regional LFO mode, so the power system with disturbance can be effectively analyzed. The results of large power grids show that the proposed method can accurately identify the dominant mode of inter - regional LFO, they are the same as the resuh that is calculated by PSASP, thereby the proposed method proved to he correct and effective.
