Many researchers presented the theoretical analysis of the doubly fed induction generator (DFIG) based wind turbines, while the experimental setup is more valid but remains a big challenge. Besides, wind power systems' most significant problem is how to get the most valuable energy with different wind speeds. Using wind speed sensors is a challenging operation in wind turbines due to the complicated maintenance and high cost. Therefore, This paper proposes an efficient and usable control system based on the WSE method to achieve the MPPT from DFIG under variable wind speed in different conditions. This paper also presents a DFIG based wind turbine as simulation and experimental investigation models. The simulation model of DFIG with their control schemes is implemented in MATLAB/SIMULINK software. While the experimental model is performed on a real prototype scale. Finally, a comparison of the simulation and experimental results was carried out to prove the practicability and validity of the proposed WSE method. Also, the simulation results show that the performance of the proposed WSE method is better than the traditional power signal feedback method.

许多研究人员介绍了基于双馈感应发电机（DFIG）的风力涡轮机的理论分析，而实验装置更有效，但仍然是一个很大的挑战。此外，风力发电系统最重要的问题是如何在不同的风速下获得最有价值的能量。由于维护复杂且成本高，在风力涡轮机中使用风速传感器是一项具有挑战性的操作。因此，本文提出了一种基于WSE方法的高效实用的控制系统，以在不同风速下，由DFIG实现MPPT的MPPT。本文还提出了一种基于DFIG的风力发电机，作为仿真和实验研究模型。在MATLAB / SIMULINK软件中实现了DFIG的仿真模型及其控制方案。而实验模型是在真实原型规模上执行的。最后，对仿真结果与实验结果进行了比较，证明了所提WSE方法的实用性和有效性。仿真结果表明，所提出的WSE方法的性能优于传统的功率信号反馈方法。
