The fixed speed pitch regulated controller

Use this control model for a fixed speed turbine (for example with a directly-connected induction generator which has a pitch- or aileron-controlled rotor.

Steady State Parameters

The pitch angle is altered in order to maintain the Demanded electrical power set-point in the full-load regime. The user should provide the Minimum pitch angle and the Maximum pitch angle to limit the range of pitch motions.

To regulate power in the full-load regime the user has the option to either select Pitch feathering or Assisted stall. If Pitch Feathering is selected, the Minimum pitch angle will be set for normal operation below rated wind speed, and the pitch (or Aileron) angle will increase above rated. If Assisted Stall is selected, the Maximum pitch setting is used below rated, and the pitch (or aileron) angle decreases (or moves to more negative values) above rated.
