摘要

采用复模态叠加方法推导了多机电力系统强迫功率振荡的稳态响应，分析了多机电力系统强迫功率振荡发生共振的条件及其振荡大小的主要影响因素。通过讨论多机弱阻尼系统共振情况下强迫功率振荡稳态响应与传统的负阻尼低频振荡响应的相似和不同之处，阐述了对多机系统强迫功率振荡稳态响应特性的一些基本认识，有助于更好地理解强迫功率振荡理论及其振荡分布特性。分别通过2区4机系统和新英格兰10机39节点系统的仿真分析对这些特性进行了验证。

Abstract

The steady-state response of forced power oscillation is presented in multi-machine power systems with complex modes superposition method. The resonance mechanism and the key factors that influence the oscillation amplitude are analyzed. The similarities and differences between the steady-state resonance response of forced power oscillation and the response of traditional negative damping low frequency oscillation are discussed in multi-machine weak damping systems. Some basic properties of forced power oscillation in multi-machine power systems are set forth. It contributes to a better understanding of forced power oscillation and oscillation characteristics. Finally， a series of simulation analysis is carried out to indicate the feasibility and validity of the analysis.
