Optimal blade pitch control with realistic preview wind measurements

  title={Optimal blade pitch control with realistic preview wind measurements},
  author={Fiona M. Dunne and Lucy Y. Pao},
In above-rated wind speeds, the goal of a wind turbine blade pitch controller is to regulate rotor speed while minimizing structural loads and pitch actuation. This controller is typically feedback-only, relying on a generator speed measurement, and sometimes strain gauges and accelerometers. A preview measurement of the incoming wind speed (from a turbinemounted lidar, for example) allows the addition of feedforward control, which enables improved performance compared to feedback-only control… CONTINUE READING
