Abstract Doubly-fed induction generators (DFIGs)-based wind turbine (WT) are the major sources of renewable energy generation around the world. The low voltage ride-through (LVRT) capability of such sources must be improved to keep them connected with the grid during faults. Due to its sensitivity to the grid disturbances, sober arrangements should be made to keep DFIG connect to the grid. Therefore, this paper implements the crowbar resistance protection scheme on the practical 153MW ADAMA-II wind farm, situated in Ethiopia, for enhancing the LVRT of WT. The dynamic performance of the DFIG-based WT incorporated with the crowbar resistance is analyzed and compared under steady-state and symmetrical grid disturbances. To show the effectiveness of the proposed scheme, the dynamic performance is analyzed and compared with the existing capacitor bank system by observing various parameters. For modeling and simulation purposes, MATLAB/Simulink software is utilized in this research study. The results verify the superiority of the proposed LVRT capability in practice.

基于双馈感应发电机的风力机低电压穿越能力分析

摘要 基于双馈感应发电机 (DFIG) 的风力涡轮机 (WT) 是全球可再生能源发电的主要来源。必须改进此类电源的低电压穿越 (LVRT) 能力，以在故障期间保持它们与电网的连接。由于其对电网扰动的敏感性，应做出清醒的安排，以保持双馈电网与电网的连接。因此，本文在埃塞俄比亚实际的153MW ADAMA-II风电场上实施撬棒电阻保护方案，以提高WT的LVRT。在稳态和对称电网扰动下，分析和比较了结合了撬棒电阻的基于 DFIG 的 WT 的动态性能。为了显示所提议方案的有效性，通过观察各种参数，分析动态性能并与现有电容器组系统进行比较。出于建模和仿真的目的，本研究使用了 MATLAB/Simulink 软件。结果验证了所提出的 LVRT 能力在实践中的优越性。
