标题(英语)

Power train for a wind power plant


摘要(英语)

A power train for a wind power plant includes a rotor (1) for driving a gear (4), wherein the rotor blades (2) of the rotor are pivotally arranged around the longitudinal axis thereof on the hub of the rotor (1). A three-phase generator (5) is connected to the gear (4) and a power supply network (12). The gear (4) is also provided with an auxiliary variable speed drive (7). Each rotor blade (2) is provided with a drive for individually rotating around the longitudinal axis thereof for levelling the rotation speed and/or the torque of the power train.
