为了抑制强迫振荡，避免与模态振荡混淆，研究了多机电力系统强迫振荡的基本原理。首先，明确制定的振荡制定强迫干扰和系统的模式形状。然后，深入研究了强迫振荡的振幅、分量和包络。因此，获得了用于减轻振荡的措施。利用受迫振动特性和包络线形状的唯一性，可以有效地检测和区分受迫振动和模态振动。10机39节点新英格兰试验系统和实际电力系统的研究结果验证了理论分析的正确性和强迫振荡检测方法的有效性。
To mitigate forced oscillation and avoid confusion with modal oscillation, fundamentals of forced oscillation in multimachine power system are investigated. First, the explicit formulation of the oscillation is formulated in terms of forced disturbances and system mode shapes. Then, forced oscillation amplitude, components and envelope are intensively studied. Consequently, measures for mitigating the oscillation are obtained. Forced oscillation can also be effectively detected and discriminated from modal oscillation by utilizing its uniqueness of components properties and envelope shapes. Study results of the 10-machine 39-bus New England test system and a real-life power system demonstrate the correctness of theoretical analyses and effectiveness of detection methods for forced oscillation.
