Brief introduction to the Darrieus wind turbines - Amics 21

The power of a wind turbine varies as shown in Fig. 9. For certain angles of rotation φ its power is negative. For a Darrieus wind turbine connected to the electrical grid, this means that at times the rotor absorbs energy from the grid, i.e., the synchronous generator connected to it via a gear as a motor.
