Definitions
- the present invention relates to a wind power plant with an asynchronous machine for determining the azimuth position of the nacelle of the wind power plant, the asynchronous machine being equipped with a first rotor / stator arrangement, in which the rotor is connected to a shaft.
- Asynchronous machines have been well known for a long time, e.g. from WO 98/40958, DE 32 34 673, WO 90/13937, US 5,838,135 and are used for a variety of drive and actuating tasks.
- An actuating task is often the movement of a machine part from a starting position into a predefinable, new target position.
- An example of an application is the adjustment of the azimuth position in wind turbines.
- This adjustment of the azimuth position namely the orientation of the nacelle in horizontal axis systems, enables the rotor to track the wind in order to be able to continuously generate electrical energy.
- the nacelle of such a wind energy installation is rotatably mounted and is moved via at least one so-called azimuth motor.
- This process is carried out by, for example, a drive pinion engaging a toothing on the tower head and adjusting the nacelle relative to the tower head by actuating the motor.
- the asynchronous machine is stopped.
- the azimuth position is not changed with every slight deviation in the wind direction. With slight changes in the wind direction, this results in an inclined flow of the rotor and the resulting yaw rate. ment around the vertical axis of the wind turbine on the nacelle. So that this yaw moment does not lead to an unwanted change in the azimuth position, the azimuth motors can be supplied with a direct current in order to generate a corresponding braking torque.
- the asynchronous machine described in the introduction has a second rotor / stator arrangement, which, however, is electrically separated from the first rotor / stator arrangement, the rotor of the second rotor / stator arrangement also being connected to the shaft.
- a rotor / stator arrangement can be subjected to a direct current in the desired direction in order to generate a desired braking torque, while the second rotor / stator arrangement is acted on by an alternating current which has a torque in rieh- device of the rotating rotating field generated and thus causes an actuation of the drive.
- each of the drives can be adjusted by the opposite direction of the torque so that it overcomes the range of mechanical play. This eliminates the mechanical play.
- the braking torque is retained because the currents act on different rotor / stator arrangements and do not overlap in their electrical effect. Mechanically, there is an overlay on the shaft, since both rotors are connected to this shaft.
- both rotor / stator arrangements of the drive are acted upon in phase with a first alternating current.
- the moments resulting in the individual rotor / stator arrangements add up to a higher total torque.
- Figure 1 is a partially sectioned view of a drive according to the invention
- Figure 2 shows an alternative embodiment of a drive according to the invention
- Figure 3 shows another embodiment of a drive according to the invention.
- FIG. 4 shows a schematic arrangement of four azimuth drives of an adjusting device on the machine house.
- reference numeral 10 denotes a drive motor according to the invention.
- This drive motor has a first rotor 12, which is connected to the shaft 20, and a first stator 14, which is connected to the first rotor 12. sammenwirkt.
- the drive 10 according to the invention has a second rotor 22, which is also connected to the shaft 20 and interacts with the stator 24.
- the two rotor / stator arrangements 12, 14; 22, 24 are combined in a housing in this exemplary embodiment, but are electrically separated from one another. This is shown by the connection terminals 15, 25 shown separately.
- FIG. 2 shows a further embodiment of the present invention.
- the rotor / stator assemblies 12, 14; 22, 24 each housed in a separate housing 10, 18.
- both act, as in the exemplary embodiment shown in FIG. 1, on the same shaft 20 which passes through the housing 10 of the first rotor / stator arrangement 12, 14 and into the housing 18 of the second rotor / stator arrangement 22, 24 reaches into and is connected to the two runners 12, 22.
- FIG. 3 Another embodiment is shown in FIG. 3.
- the two rotor / stator arrangements 12, 14; 22, 24 housed in separate housings 10, 18.
- both rotor / stator arrangements 12, 14; 22, 24 own machine shafts 16, 26, which in turn act on a common shaft 20.
- This embodiment allows in particular the use of mechanically smaller components and a relatively simple replacement of an individual component in the event of a fault.
- FIG. 4 shows a schematic arrangement of four azimuth drives of an adjusting device on the machine house of a wind power plant.
- wind turbines have an active drive for tracking wind direction. This rotates the machine head (nacelle) of the wind turbine so that the rotor blades of the rotor are optimally aligned in the direction of the wind.
- the active drive for the wind direction tracking is an azimuth drive 1 with the associated azimuth bearing 2 and is usually located between the tower head and the machine house of the wind turbine.
- azimuth drive 1 with the associated azimuth bearing 2 and is usually located between the tower head and the machine house of the wind turbine.
- larger wind turbines are usually equipped with several drives, for example four drives, as shown in Fig. 4.
- the four drives 1 are evenly distributed over the circumference of the tower head 3 (an uneven distribution is also possible).
- asynchronous motors are used as azimuth drives, as have already been described above, the shaft 20 (FIG. 1) acting directly on the drive pinion 4.
