This paper presents a novel strategy for controlling the yaw rotation of a new twin wind turbines structure without a dedicated actuator. The idea of such strategy is to create a difference between the powers produced by the wind turbines, by modifying the generators torques, in order to force the structure face the wind. Given that the wind turbine performance is affected by the wind variation, a...
The control of a new concept of the twin wind turbines is presented in this paper. This structure has two identical wind turbines, ridden on the same tower. The two wind turbines drive two identical permanent magnet synchronous generators (PMSG), and they can pivot face the wind without using the yaw actuator. The control of the full system including the mechanical and electrical parts is ensured...
In this paper a Backstepping Controller (BC) and a Maximum Torque Per Ampere (MTPA) strategy have been designed in order to control a permanent magnet synchronous generator (PMSG) at below and above rated wind velocity. At low wind speed, the wind turbine operates in partial load (PL) and the maximum amount of power is extracted. When the wind speed reaches the nominal value, the wind turbine operates...
