Definitions
- the invention relates to a wind power plant with at least one drive train driven by wind power, a transmission and a generator.
- Wind turbines generate electrical energy by rotating their rotor-blade hub via a downstream gearbox that is mechanically connected to a generator.
- These are combinations of individual elements, such as gears, clutches and generators, which are arranged axially one behind the other and have a correspondingly high weight and corresponding space requirement.
- the invention is therefore based on the object of creating a wind power installation in which the weight of the generator and transmission and their space requirement is reduced compared to conventional installations and can be operated almost maintenance-free. Furthermore, such a gear generator unit should also be usable for offshore systems.
- the task is solved by integrating the transmission in the generator.
- the output of the gearbox is thus mechanically coupled to the rotor of the generator.
- the rotor which can preferably be a permanent magnet excited rotor or also an electrically excited rotor, is designed as an internal or external rotor.
- the external rotor is supported on one or both sides on the fixed gear stage.
- This bearing is integrated in the stator structure.
- the bearing is preferably insulated and thus suppresses any circulating currents. A small and even air gap is also achieved.
- the gearbox output stage can be designed as a planet carrier or as an internal toothing.
- the gear drive stage that is to say the drive train, has internal teeth or a pinion carrier.
- the arrangement of the gear stages can lie within the stator structure when supported on one side and in front of the stator structure when supported on both sides.
- the bearings themselves are designed as conventional roller or plain bearings. However, they can also be designed as magnetic or hydrostatic bearings with the system components required for this, such as electrical control and regulation technology, possibly pumps and the necessary monitoring technology.
- the fixed stator structure on the one hand carries the electrically relevant generator components and on the other hand it is designed to accommodate one or more fixed gear stages.
- Monitoring devices of braking devices and corresponding control devices for rotating the rotor blades Other monitoring devices such as e.g. Sensors for structure-borne noise measurement of the gearbox, detection of the wind speed and the angle of the rotor blades.
- the existing operating data now enable automatic or manual interventions in the wind turbine on site or from a central control room.
- This data transfer which takes place as bidirectional communication, can advantageously be used wirelessly, particularly in off-shore systems.
- FIG. 1 and 2 each show a wind power plant 1, not shown, in which the wind energy is converted into rotation of a drive train 2, which is rotatably mounted in a housing structure, not shown.
- the housing structure advantageously has air or liquid cooling devices, not shown, in particular of the electrical equipment.
- the drive train 2 is hollow at least where there is an internal toothing 12.
- the teeth can be oblique or straight.
- By rotating the Drive train 2 is also set in rotation via one or more gear output stages 4, a fixed gear 3 and a mechanical connection 9 of the external rotor 8.
- the part of the external rotor 8 opposite a stator 5, that is to say the rotor 7 with its permanent magnets 6, forms a generator.
- the external rotor 8 is understood to mean the mechanical structure that contains the part that interacts electromagnetically with the stator 5, ie the rotor 7, and transmits the drive torque from the drive train 2 to the generator.
- the stator 5 itself is integrated in the housing structure, not shown in detail.
- the external rotor 8 is offset from the housing structure 10 via a bearing 11.
- the bearing 11 is carried out on both sides in both embodiments; however, as indicated in Fig.l, it can also be carried out on one side. This leads to to further reduce assembly and maintenance work.
- the storage is advantageously carried out in isolation.
- the gear stages are arranged depending on the electrical design of the generator with one-sided mounting within the stator structure and with double-sided mounting essentially in front of the stator structure.
- a very compact wind turbine 1 can thus be set up, since the integrated construction of a transmission with the transmission output stages 4, a fixed gear 3 and • a generator enables a compact construction.
- the wind turbine can be extensively equipped with internal runners.
- External and internal rotors can also be electrically excited.
