This article presents a library of second-order models for synchronous machines that can be utilized in power system dynamic performance analysis and control design. The models have a similar structure to that of the so-called classical model in that they consist of two dynamic states, the power angle and the angular speed. However, unlike the classical model, they find applications beyond first swing stability analysis, i.e., they can be utilized for multi-swing transient stability analysis. The models are developed through a systematic reduction of a nineteenth-order model using singular perturbation techniques. They are validated by comparing their response with that of the high-order model from which they were derived, as well as that of other synchronous machine models existing in the literature, such as the so-called two-axis model and the so-called one-axis model.

同步机器的二阶模型库

本文介绍了可用于电力系统动态性能分析和控制设计的同步电机二阶模型库。这些模型与所谓的经典模型具有相似的结构，因为它们由两个动态状态、功率角和角速度组成。然而，与经典模型不同的是，它们的应用范围超出了第一次摆动稳定性分析，即它们可用于多摆动暂态稳定性分析。这些模型是通过使用奇异扰动技术对 19 阶模型进行系统化约而开发的。通过将它们的响应与导出它们的高阶模型的响应以及文献中存在的其他同步电机模型的响应进行比较来验证它们，
