  • Control system

    Layout of the controller, Wind turbine control
    Wind turbine control
    The rotational speed and the pitch angle of the wind turbine are modified at every instant depending on the wind speed. The control system chooses the adequate values for these variables.
    Depending on the wind-speed, 4 setups are possible:
    ① At low wind speed, with the generator disconnected from the grid.
    ② At medium wind speed, with the generator connected to the grid, but the rated power is not achieved.
    ③ At high wind speed, the turbine produces the rated power.
    ④ At very high wind speed (cut-out wind speed), the generator is disconnected and the wind turbine is stopped.
