| 摘 要： | 区域间振荡会严重影响系统的正常运行,一旦线路发生连锁故障,将引发更大的系统扰动。通过频率监测网捕捉到了美国东部互联电力网发生的6例典型的区域间振荡现象并使用矩阵束方法对电压相角相对值多路数据进行了模态分析,计算了相应的振型参数,提出了每一个振荡现象案例的主模的振型,分析其结果并给出了东部互联电网的区域间振型的分布情况。

| Abstract: | Inter-area oscillation will seriously affect the normal operation of the system. Once the line cascading failure occurs, the system will produce greater disturbance. The inter-area oscillations occurring in the Eastern Interconnection of United States were investigated by six typical cases using the frequency monitoring network （FNET） data. The matrix pencil method of multiple signals was used for the modal analysis. The parameters related to mode shape were calculated. The mode shapes for the dominant mode are revealed for each case. Analysis results depict a view of inter-area mode distribution in the Eastern Interconnection. |
