초록

A system for providing dynamic pitch control in a wind turbine. In accordance with an embodiment, the dynamic pitch control uses a starting spring to pitch the blades of the wind turbine into a starting position that is suited for very low wind speeds. The pitch control then automatically pitches the blades into a run position as the rotation speed increases, using a combination of a rotational mass and a restraining spring. This allows the turbine to be started, and to generate power, at a much lower starting wind speed yet still operate at optimal spee...

1. A system for providing pitch control in a wind turbine, comprising: a turbine shaft that is adapted to rotate about its longitudinal axis to generate electrical power;a plurality of blades coupled to the shaft, and oriented to receive wind power and cause rotation in the turbine shaft, wherein each of the plurality of blades can be pitched about its longitudinal axis to expose more or less of the blade to the wind power;a pitch control mechanism including a combination of springs and mass, which pitches the blades at a lower starting wind speed into t...
