中文摘要：
该文根据电力系统连续体模型中线性化的波动方程，用解析方法研究机电波的传播特性。根据Peterson法则，研究连续体模型中的集中参数元件发电机对机电波传播过程中反射和透射的作用，证明连续体电力系统的机电动态能表达为机电波在连续体2端多次反射和透射过程的叠加，为从机电波传播的角度揭示电力系统机电动态的内在机理建立了一定的基础。最后通过对1个实例的仿真分析，证实该文理论的正确性。
英文摘要：
According to the linearized wave equations in the continuum model for power systems, it is studied that the characteristics of electromechanical wave propagation using the analytical method. According to Peterson＇s rule, it is presented that the influence of the lumped-parameter elements, such as generators, existed in the continuum to the reflection and transmission of electromechanical wave propagation. Furthermore, it is proved that the electromechanical dynamics in the continuum power systems can be expressed as the superposition of multi-reflection and transmission of traveling wave initiated at both terminals of the continuum. A theoretical basis for revealing the internal mechanism of electromechanical dynamics in the viewpoint of wave propagation is established. Finally, the simulation results of a radial power system validate the correctness of the theory.
