Accurate estimates of the electromechanical disturbance propagation in a power system play an important role in taking preventive, corrective, and in-extremis control actions. This paper proposes an analytical method for disturbance propagation investigation based on the electromechanical wave theory. A frame structure model is developed that allows us to derive an analytical relationship between the disturbance propagation and the inertia, the generator reactance, bus voltage, and disturbance source frequency. In addition, the disturbance attenuation and the degree of disturbance propagation are studied. Numerical results performed on a multi-machine chain network and the IEEE 118-bus test system demonstrate the effectiveness of the developed method.

一种基于机电波法的扰动传播研究分析方法

电力系统中机电干扰传播的准确估计在采取预防、纠正和极端控制措施方面发挥着重要作用。本文提出了一种基于机电波理论的扰动传播研究分析方法。开发了一个框架结构模型，使我们能够推导出扰动传播与惯性、发电机电抗、母线电压和扰动源频率之间的分析关系。此外，还研究了干扰衰减和干扰传播程度。在多机链网络和 IEEE 118 总线测试系统上执行的数值结果证明了所开发方法的有效性。
