BLADE PITCH SYSTEM FOR A WIND TURBINE GENERATOR AND METHOD OF OPERATING THE SAME |
摘要 |
A wind turbine blade pitch control system includes a blade pitch drive mechanism coupled to a wind turbine blade and an electric power source coupled to the blade pitch drive mechanism. The system also includes switch devices coupled to portions of the electric power source, and the switch devices are coupled to the blade pitch drive mechanism. The system further includes a controller coupled to the blade pitch drive mechanism and the switch devices. The controller is configured to store a plurality of operational measurements of the blade pitch drive mechanism and the switch devices. The controller is programmed to change an angular rate of change of a pitch angle of the wind turbine blade by opening and closing the switch devices in a predetermined sequence. |
