论文摘要
电力系统通常在不同的干扰后经过电磁和机电瞬态过程。学习特征及其之间的差异很重要，但对于主修电力系统的学生而言并不容易。本文提出了一种基于模拟的方法，可以全面研究两种类型的瞬态波，构成了电力系统瞬态和稳定性课程的实验部分。在这种方法中，开发了三个具有不同复杂级别的模型，以同时显示时间域中两种类型的瞬态波。然后，将开发的模型证明为测试床，用于研究与两种类型的瞬态相关的各个方面，例如由不同的干扰引起的波形，影响传播速度的因素以及入射波与反射波之间的相互作用。此外，通过开发电力系统事件地点应用来证明理论对实践工程研究过程，该应用的灵感来自机电波传播研究。提出的各种复杂性水平的教育过程和模型为电力系统瞬变和动态研究提供了一种创造性和互动的方式。
Power systems usually go through electromagnetic and electromechanical transient processes after different disturbances. Learning the characteristics and the differences between them are important but not easy for students majoring in power systems. This paper presents a simulation-based approach to comprehensively study the two types of transient waves, constituting the experimental part of the power system transient and stability course. In this approach, three models with different levels of complexity are developed to simultaneously show the two types of transient waves in the time domain. The developed models are then demonstrated as testbeds for investigating various aspects related to the two types of transient, such as waveforms induced by different disturbances, influencing factors on the propagation speed, and the interaction between incident waves and the reflective waves. In addition, a theory-to-practice engineering research process is demonstrated through developing a power system event-location application, which is inspired by electromechanical wave propagation study. The proposed education process and models at various complexity levels provide a creative and interactive way for power system transients and dynamics study.
