摘要:
A differential gearing for an energy generation plant, in particular for a wind power station, has three drives and outputs, a first drive being connected to a drive shaft of the energy generation plant, one output being connected to a generator (8), and a second drive being connected to an electrical machine as differential drive (6). The transmission ratio of the differential gearing (3) can be fixed at 1 by way of a brake (20).

A differential gear for an energy production plant, in particular for a wind power plant, has three drives and three power take-offs, whereby a first drive is connected to a drive shaft of the energy production plant, a power take-off is connected to a generator (8), and a second drive is connected to an electric machine (6) as a differential drive. The first drive that is connected to the drive shaft rotates at a basic speed. The speed range of the first drive is at least −/+6.0% and at most −/+20.0% of the basic speed, while the electric machine (6) is operated at nominal speed.
摘要:
The invention relates to a method and device for braking the rotor of a wind energy plant, comprising rotor blades (3) mounted to rotate on the rotor with electrical devices in the rotor hub (2), such as an actuator (4, 5) for the rotation of the rotor blades (3), whereby on drop-out of the power supply to the electrical devices (4, 5), a rotor brake is activated (11), whereupon the rotor blades (3) as a result of the braking torque of the rotor brake (11) are rotated into the feathered position by means of the inertia thereof.
摘要:
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.
