Description

Ground-mounted plant for power generation and process for operating a plant

The invention relates to a ground-mounted plant for power generation and a

Method for operating such a system.

Modern wind turbines for power generation include one

Wind power generator installed on a so-called tower. Wind power generators convert mechanical into electrical power and can, for. B. be designed as three-phase asynchronous or synchronous generators. Such wind power generators are designed here mechanically for operation with rotor blades. However, the operation with these usually long rotor blades, as explained above, requires the installation high above a ground.

It is desirable to expand a field of application for wind power generators.

The solution of the technical problem results from the objects with the features of claims 1 and 17. Further advantageous embodiments of the invention will become apparent from the dependent claims.

It proposes a ground-mounted system for power generation. The plant comprises at least one wind power generator. In this case, the wind power generator may designate a generator which, in particular electrically and / or mechanically, is designed for operation with rotor blades. Such wind power generators are already available on the market. The wind power generator can be mounted directly on the ground, in particular without a tower. Of course, but still a corresponding fastener, z. B. a mounting plate or a foundation between the wind turbine and the bottom can be arranged. It is essential that the wind power generator is mounted near the ground.

Furthermore, the system comprises at least one motor. The engine may be any means for generating a driving force or a drive torque. The engine may be designed, for example, as an electric motor, as an internal combustion engine or as a gas turbine. The at least one wind power generator, in particular a drive shaft of the

Wind power generator, and the engine, in particular an output shaft of the engine, are mechanically coupled. In this case, a mechanical coupling may designate a coupling via which torques, directions of rotation, rotational speeds and / or forces are transmitted and / or converted.

According to the invention, the wind power generator is a replacement for rotor blades with a

Peak weight carrier equipped.

The peak weight carrier may hereby designate an element or component which has or forms two or more than two free ends which are arranged around a center or a central axis of the peak weight carrier, wherein a weight with a predetermined mass is fastened or formed at the free ends is. In particular, the free ends may be disposed at predetermined radial distances from the center or central axis, particularly on a circular line about the midpoint / center axis of the peak weight carrier. The peak weight carrier can in this case be attached to the drive shaft of the wind power generator.

The peak weight carrier may in this case replace or mechanically simulate a rotor of a wind turbine, wherein the mass of the weights and / or their distance from the center or the central axis is selected so that an inertia of the peak weight carrier corresponds to the moment of inertia of a rotor blade or not more than a predetermined amount deviates from this. The moment of inertia can in this case be determined with respect to an axis of rotation of the wind power generator, wherein the axis of rotation may correspond to the previously explained center axis of the peak weight carrier. In particular, however, the radial distance of the free ends (very) is much shorter than the length of a rotor blade of a rotor with the same or comparable moment of inertia.

For example, the peak weight carrier may comprise a rod-shaped member and two weights, the weights being arranged or formed at free ends of the rod-shaped member, a central portion of the rod-shaped member being fixed to the drive shaft. Of course, the

Peak weight carrier also designed as a multi-pointed star with more than two pips be in each case, wherein at the free ends of the tooth-forming structure weights are arranged or formed. A focus of a section of the

Peak weight carrier, which forms a free end and thus mechanically simulates or replaces one of the rotor blades, can thus be arranged in the region of the free end. A center of the multi - pointed star can be found on the drive shaft of the

Wind power generator to be attached. It is also possible that a weight is not arranged exclusively at the free end of the peak weight carrier, but distributed over at least a part of the structure is formed.

This advantageously results in that a wind power generator designed for operation with a rotor can be used floor-mounted to generate power since the peak weight carriers can be designed such that a maximum dimension, for example a maximum length of tines, is less than that of a corresponding rotor.

The proposed system also allows advantageously an operation of a wind power generator with arbitrary forms of energy, such as electrical energy, gas or fuel. Since such energy sources can be generated sustainably in an advantageous manner, for. As biogas or biodiesel, thus can also be an ecological generation of electricity using existing and already available wind power generators done.

Alternatively, the wind power generator is equipped as a replacement for rotor blades with an at least partially arcuate force transmission element. The

Force transmission element may in this case comprise at least one arcuate portion. The arcuate portion may in this case be part of a mechanical coupling between the drive shaft of the wind power generator and another shaft mechanically coupled to the motor. For example, For example, the arcuate portion may be attached to a drive shaft of the wind turbine or to the other, with the engine

attached mechanically coupled shaft.

The arcuate portion may extend from a mounting portion of the arcuate portion in the radial and axial directions of the shaft. Thus, an arcuate portion may also consist of several juxtaposed or fixed straight sections, wherein the entirety of the straight Extends portions in the radial and axial directions of the shaft away from a mounting portion of the arcuate portion. For example, the at least two straight sections may be attached to each other at an angle less than 180 °. The attachment portion may in this case be fastened to one of the previously explained shafts. Here, the arcuate portion can form at least one free end. This can then be connected again via suitable connecting portions with the respective further shaft. The arcuate force transmission element may be formed as a peak weight carrier without weights.

In a further embodiment, the engine is mechanically coupled via at least one transmission to the at least one wind power generator. The transmission, in particular an input shaft of the transmission, may in this case be mechanically coupled to the engine, in particular an output shaft of the engine.

In a further embodiment, the at least one wind power generator is mechanically coupled to the engine via at least one gear transmission. In addition to the at least one gear transmission, however, further transmissions for coupling the engine and the wind power generator may be provided. It is also conceivable that the motor and the generator are mechanically coupled via a plurality of gear transmission. The gear transmission can be arranged at any point along the mechanical power transmission path between the engine and wind power generator.

For example, a generator-side gear may be mounted on or on the drive shaft. Further, a motor-side gear may be mounted on or on a shaft which can be driven by the motor. The gears may in this case be for engaging a speed / torque in engagement with each other or interact with each other. The motor driven shaft can be an output shaft of the engine or one with this

Output shaft be mechanically coupled shaft. The shaft which can be driven by the motor can, in particular, have the output shaft of a further explained in more detail below Getriebes be, for example, a bevel gear.

However, it is also possible that the number of teeth of the engine side gear larger than the number of teeth of the generator side gear. A suitably designed gear transmission may alternatively or cumulatively also be provided for coupling the motor with a further transmission explained in more detail below. This results in a reliable manner a reliable

Translation of speeds / torques from the motor to the wind power generator.

The ball bearings, in particular a central center axis of the ball bearings are hereby spaced apart from each other by a predetermined distance. The Twin ball bearing element serves to set a fixed distance between the two shafts and thus, for example, to ensure the engagement of the gears in each other or to ensure the timing belt or chain tension. As a result, the reliability of the ratio of speeds / torques can be increased in an advantageous manner.
