To grasp the foundation of wind turbine control, it's essential to understand the three primary basic control mechanisms traditionally used: pitch control, generator torque control, and yaw control. . Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. The control system also guarantees safe operation, optimizes power output, and ensures long structural life. Turbine rotational speed and the generator speed are two key areas that you must control for. . In this paper, we first review the basic structure of wind turbines and then describe wind turbine control systems and control loops. Gearbox The gearbox accelerates. .
