摘要： A wind turbine includes a hub sub-system comprising a main hub and a shaft adapted to rotate about an axis, and a plurality of turbine blades having a pitch angle. The blades are adapted to drive the rotation of the hub sub-system to a first speed. The wind turbine further includes a pitch drive sub-system including a driving element adapted to rotate about the axis at a second speed, and further adapted to control the pitch angle of the turbine blades in relation to a difference between the first speed and the second speed. A slip enhanced generator enables the hub sub-system to rotate at a different speed than the pitch drive sub-system. The difference in speed is governed by a slip function. The wind turbine further includes an active control system adapted to control the second speed of the driving element.
