Research on variable pitch control method based on wind wheel acceleration

With the rapid development of wind power, wind power operation and maintenance has changed from simple passive operation and maintenance to lean active operation and maintenance. Based on the fault alarm and on-site investigation, this paper analyzed the operation data of the faulty unit, compared the fault time and historical operation data vertically, and compared the difference of the operation data of each unit horizontally, and analyzed that the turbulence intensity was an important cause of the accident. To solve this problem, a feedforward control method based on rotor acceleration is proposed, and the feasibility of this method is verified by simulation.
