Variablespeed Operation

If the speed of the rotor can be continuously adjusted such that the tip speed ratio remains constant at the level which gives the maximum CP then the efficiency of the turbine will be significantly increased. Active pitch control is necessary to maintain a constant tip speed ratio but only in the process of adjustment of rotational speed; the pitch angle should always return to the optimum setting for highest efficiency. Pitch control regulation is also required in conditions above the rated wind speed when the rotational speed is kept constant.
