Definitions

  • the invention concerns a wind-power system with a tower built from several tower segments, with a generator for generating power arranged in the region of the tower head, with a power module, and with current-carrying means for carrying the generated current from the tower head.
  • the electrical power module of a wind-power system which includes electrical units, such as transformers, service cabinets, optionally, rectifiers, medium-voltage networks, low-voltage distribution devices, etc., is arranged underneath the level of the generator and frequently in the region of the tower base of the wind-power system. For all or some of these components, usually a small, separate building is provided outside of the wind-power system.
  • the current-carrying means therefore must essentially fulfill the purpose of carrying the current generated and possibly preprocessed in the region of the tower head away from the tower head.
  • the present invention provides a wind-power system, which can be erected more easily and thus also more economically and more quickly, and in which the power module is not absolutely necessarily in the region of the tower base.
  • the current-carrying means are premounted in a segmented way into the tower segments and in that the power module is arranged at least partially in the region of the tower head and/or at a distance from the tower base.
  • the segments of the current-carrying means are thus prefabricated and preferably attached to the tower segments before the tower is erected from the individual tower segments. Thus, it is no longer necessary to draw cables through the tower in a complicated process after erecting the tower. Due to the means according to the invention, the total erection time of the wind-power system can be shortened and the costs for the erection reduced, without having to take into account any technical disadvantages.
  • the power module be arranged at least partially in the region of the tower head and/or at a distance from the tower base.
  • the power module is mounted—partially or completely—within or outside the gondola.
  • the power module is arranged—partially or completely—on land, for example, in the closest area of solid ground or on a nearby island and to connect the wind-power system to the power module through underwater cables.
  • the power module has at least two power module units, one of which is arranged in the region of the tower head and the other underneath the tower head, thus in the region of the tower base or at a distance from the tower base.
  • the current-carrying means are then provided essentially to connect the two power module units.
  • the segments of the current-carrying means are rigidly connected in the assembled state to the associated tower segment only in one region, preferably in the uppermost region.
  • This attachment to the tower segment is realized preferably before the tower is erected, so that the tower segments, including the attached segments of the current-carrying means, are prefabricated.
  • the segment of the current-carrying means is attached rigidly to the tower only at one point, it is suspended tightly but does move within certain limits on the inner wall of the tower segment and thus can also be aligned in order to form as good and easy a connection as possible to the next segments of the current-carrying means of the next tower segment.
  • additional holding elements can also be provided on the inner wall of the tower, with which the segments of the current-carrying means are rigidly connected before or after the tower is erected in order to fix these as well as possible.
  • the current-carrying means are formed as cables, for bypassing flanges or parts projecting from the tower inner wall, the lengths of the cable sections can be dimensioned in the tower segments so that bypassing these areas is possible without a problem.
  • busbars as current-carrying means
  • flexible connecting bars are provided for bypassing parts projecting from the inner wall of the tower and/or for connecting busbar segments. These are used after the tower is erected to connect the busbar segments, if these do not reach each other directly or if gaps or other obstacles between the busbar segments, for example, a flange on the tower bar segment, must be bypassed.
  • a protective sleeve especially a protective sheet, is provided, which is rigidly connected, for example, to the inner wall of the tower and protects the current-carrying means completely from touch.
  • This protective sleeve can also be split into individual segments, which are premounted to the tower segments just like the segments of the current-carrying means. This configuration further shortens the time and simplifies the construction of the wind-power system.
  • the invention also concerns a tower segment for a tower of a wind-power system, which is built from several tower segments and which has a generator for generating power in the region of the tower head.
  • the tower segment is characterized in that a current-carrying means segment for carrying the generated current from the tower head is premounted in the segment.

  • FIG. 2 a section of such a wind-power system with two tower segments
  • FIG. 3 a perspective representation of busbars provided according to the invention
  • FIG. 4 a representation of a first wind-power system according to the invention
  • FIG. 5 a representation of a second wind-power system according to the invention.
  • FIG. 6 a representation of a third wind-power system according to the invention.
  • the wind-power system 1 shown schematically in FIG. 1 and described in German Pat. No. 10 152 557 has a tower 2 with a foundation 3 , a gondola 4 supported so that it can rotate in the region of the top of the tower, as well as a power module 7 arranged in the region of the tower base, for example, in a small, separate housing.
  • a rotor supported so that it can rotate about a horizontal axis with several rotor blades 5 , as well as an electrical generator 6 .
  • the rotor is set in rotation by the force of wind acting on the rotor blades 5 and drives the generator 6 for generating electrical power.
  • busbars For transmitting the energy generated by the generator 6 to the power module 7 , which has numerous electrical units, such as a transformer or optionally a rectifier for further processing of the electrical power before it is fed into the power network or transmitted to a load, according to the invention, there are busbars, preferably two busbars, attached to the wall by means of attachment elements 10 in the interior 8 of the tower 2 . These are electrically conductive and connected electrically to the power module 7 by means of a cable 11 to the generator, as well as by means of a connecting line 12 , which preferably leads through the foundation 3 and the subsoil.
  • the busbars 9 are rigid and preferably comprise individual busbar segments, as shown in more detail, for example, in FIG. 2 .
  • the busbars 9 are rigid and preferably comprise individual busbar segments, as shown in more detail, for example, in FIG. 2 .
  • two tower segments 21 , 22 are shown, from which the tower 2 is preferably built.
  • Such tower segments 21 , 22 can be composed of, for example, steel or also concrete.
  • the busbar segments 91 , 92 are rigidly attached to the corresponding locations of the individual tower segments 21 , 22 just before the tower 2 is erected.
  • the attachment of the busbar segments 91 , 92 is realized only in the upper region of the associated tower segment 21 , 22 by means of an attachment device 10 , while the remaining part of the busbar segments 91 , 92 is still movable within certain limits in order to simplify the connection to subsequent busbar segments.
  • connecting bars 13 are used, whose shape can be changed by hand when attaching to the two busbar segments 91 , 92 .
  • These connecting bars 13 can compensate for material expansions or contractions, e.g., due to temperature fluctuations.
  • FIG. 3 a perspective illustration of two parallel busbar segments 911 , 912 is shown. These are screwed tightly to the holding device 14 by means of screws 15 .
  • insulation means can be provided in order to insulate the busbar segments 911 , 912 from the holding devices 14 .
  • the holding devices 14 themselves can also, of course, be produced from an insulating material.
  • the holding device 14 itself is screwed tightly to the inner wall of the tower segment.
  • a protective sheet 16 is also provided, which can be installed already in the individual tower segments just like the busbar segments 911 , 912 before the tower 2 is erected.
  • a guide bar 17 which can be composed of, for example, a rigid rubber, on the one hand this protective sleeve is fixed and on the other hand it is insulated from the tower segment.
  • other means which are not shown here, can also be provided.
  • FIG. 4 shows a first configuration of a wind-power system according to the invention.
  • the power module 7 is preferably arranged within the gondola 4 and connected directly to the generator 6 by means of cables 18 .
  • the generated power After the generated power has been processed in the power module 7 , it is led via another cable 19 to the busbars 9 , there guided through the tower to the tower base, from where it is discharged outwards via a connecting line 12 , for example, to a substation 40 , which can lie close to or far removed from the wind-power system.
  • An alternative position of the power module 7 ′ indicated by dashed lines, can also be attached to the gondola 4 on the outside. Connecting cables from the generator 6 to the power module 7 ′, as well as from there to the busbars 9 , are left out for reasons of clarity.
  • FIG. 5 shows another configuration of a wind-power system according to the invention.
  • the power module comprises at least two power module units 71 , 72 .
  • the first power module unit 71 is in turn arranged within the gondola 4 and performs initial processing of the generated power, for example, initial conversion to a different voltage range. Further processing of the generated power is then performed in the second power module unit 72 , which is arranged underneath the tower head, for example, as shown in the region of the tower base.
  • the second power module unit 72 can also be arranged vertically underneath the tower 2 on the foundation 3 or far removed from the tower base.
  • the first power module unit 71 can also be arranged outside on the gondola 4 , as shown in FIG. 4 .
  • FIG. 6 shows a configuration of a wind-power system according to the invention, which is formed as a so-called off-shore wind-power system.
  • this wind-power system 1 stands on another foundation 3 ′ anchored on the sea floor 25 .
  • the power module can also be arranged in the region of the tower head or within the tower in the region of the tower base.
  • the power module 7 is arranged on land 30 and the power discharged from the tower head by means of the busbars. 9 is transmitted via underwater cables 12 ′ to the power module 7 . This has the advantage that the power module 7 does not require extra protection from negative effects of seawater and that maintenance on the power module 7 is significantly simpler.
