Embodiment Construction

[0012] The drawing is a schematic illustration of a wind power plant according to the invention, which comprises a windmill 1 and two generators 2 , 3 which are designed as ring generators and are mechanically coupled to one another via a differential 4 . The counter-rotating rotors 5 , 6 of the generators 2 , 3 are each connected to a shaft wheel 7 , 8 of the differential 4 , wherein the windmill 1 is arranged on a compensating gear 9 of the differential 4 . The stators 10, 11 of the generators 2, 3 are connected through a hollow shaft 12 to form a thrust bearing, and the differential case 13 of the differential 4 is rotatably mounted on the thrust bearing. Each generator 2 , 3 has an axis of rotation oriented at right angles to the axis of rotation of windmill 1 embodied as a leeward rotor. The generators 2 , 3 are electrically connected to each other through a collector regulator 14 . In order to establish this connection, it is necessary to pass (not shown) generator elec...

Abstract

The power plant has a power generating device including two ring generators (2, 3). The generators are connected with each other using a differential gear (4). The generators have rotors (5, 6), which are connected with axle rods (7, 8) of the differential gear. A wind turbine (1) e.g. leeside turbine, is arranged on a compensating wheel (9) of the differential gear. The generators have stators (10, 11) that are connected with each other at a thrust bearing at which a differential bearing (13) of the differential gear is rotatably retained.

Description

technical field [0001] The invention relates to a wind power plant, comprising at least one windmill and a power generating device. Background technique [0002] Existing wind power equipment uses servo motors for yaw control. Under the action of the servo motors, the entire bow of the wind power equipment rotates around the vertical axis by means of so-called azimuth bearings. The rotational speed regulation preferably takes place via a servomotor for adjusting the blade angle of the windmill. All servomotors receive control signals from a control device with a plurality of wind measuring devices arranged at the bow. The disadvantage of an exposed forward position is that these wind measuring devices are constantly affected by weather elements. Phenomena such as icing and corrosion in particular can render wind measuring devices inoperable or restricted. In addition, unstable wind conditions will also cause some disturbance factors. In order to compensate these disturba...
