Many real-world scenarios confirmed insights developed based on the dq-frame nonlinear analytical model for doubly-fed induction generator (DFIG)-based type-3 wind subsynchronous resonance (SSR) study by the authors in 2010. A few real-world observations do not align with the simulation results from that model. In real-world scenarios, when a type-3 wind farm is radially connected to a series compensated line, even at a low compensation level, SSR occurs. This phenomenon has not been replicated by the nonlinear analytical model. In this paper, we revisited the analytical model by including phase-locked-loop (PLL). A modular modeling approach is presented in this paper. The inputs and outputs of each subsystem and the interconnections among subsystems are identified first. The overall system is then developed with all blocks integrated. The analytical model is capable of dealing with various transmission topologies, providing both large-signal time-domain simulation results and small-signal analysis. The new analytical model can successfully replicate the aforementioned phenomena and provide insights of type-3 wind SSR phenomena. The accompanying software package will be posted in the public domain.

许多真实世界的场景证实了作者在 2010 年基于双馈感应发电机 (DFIG) 的 3 型风次同步谐振 (SSR) 研究的 dq 框架非线性分析模型开发的见解。 一些真实世界的观察结果与该模型的仿真结果不一致。在实际场景中，当 3 类风电场径向连接到串联补偿线路时，即使在低补偿水平下，也会发生 SSR。这种现象没有被非线性分析模型复制。在本文中，我们通过包含锁相环 (PLL) 重新审视了分析模型。本文介绍了一种模块化建模方法。首先确定每个子系统的输入和输出以及子系统之间的互连。然后开发整个系统，其中集成了所有块。该分析模型能够处理各种传输拓扑，提供大信号时域仿真结果和小信号分析。新的分析模型可以成功复制上述现象，并提供对 3 型风 SSR 现象的见解。随附的软件包将发布在公共领域。
