Definitions
- This invention relates to a buoyant wind power station. More particularly, it relates to a buoyant wind power station in which a wind turbine is placed on an installation.
- a floating vessel in any form, such as a buoy, a barge, a ship or a platform.
- Floating installations are subjected to partly considerable environmental forces from winds, currents and waves. Accord- ing to the kind of installation, environmental forces may set up considerable movements in the six degrees of freedom. In windmill structures, which are relatively tall, movements from pitching and rolling may constitute structural restrictions in the construction of the wind power station.
- additional floats are placed around a main float.
- the additional floats are of such a design that they provide considerably increased buoyancy if they are moved down into the water.
- WO 03/004869 discloses a buoyant wind power station in which the design of the float together with the moorings restricts the tilt of the windmill.
- the invention has for its object to remedy or reduce at least one of the drawbacks of the prior art .
- a buoyant wind power station in which a wind turbine is placed on an installation is provided and is characterized by the installation being provided with a stabilizing gyro.
- a stabilizing gyro arranged in the wind power station will counteract angular deflections of the wind power station around angular axes in directions other than the stabilizing gyro's own rotational axis. If the gyro rotates around a vertical axis, angular deflections in the form of rolling and pitching due to at least winds, waves and currents will be counteracted.
- the positioning of the stabilizing gyro in the installation depends on the design of the installation and must, on the basis of known principles, be adjusted with respect to whether the centre of gravity of the wind power station is above or below the centre of buoyancy, among other things.
- the stabilizing gyro may be constituted by one or more masses that are arranged in suitable positions, for example as part of the wind turbine, the axle, gear or generator of the wind turbine .
- the stabilizing gyro may be constituted by a separate flywheel rotating at relatively great speed, or a relatively large mass rotating at considerably lower speed.
- the relatively large mass is positioned at a relatively low level in the installation, it may form part of the ballast of the installation.
- the mass of a slow-rotating stabilizing gyro may constitute 10-80 % of the installation weight, for example. Calculations show that at speeds of between 5 and 20 revolutions per minute, a good effect is achieved when the mass constitutes 30- 60 % of the installation weight.
- the stabilizing gyro may surround the drive shaft of the wind turbine. If the drive shaft is vertical, as, with advantage, it may be if a Gelhard or Darrieus turbine is used, or also with other turbines when the generator of the windmill power station is placed in the installation, the stabilizing gyro will function in accordance with the intention.
- the stabilizing gyro may be driven by the drive shaft via a gear, or directly by the drive shaft.
- the stabilizing gyro may be driven by, for example, an electromotor.
- the installation may be provided with at least two stabilizing gyros, wherein two stabilizing gyros may be counter- rotating.
- the stabilizing gyros may have different axes of rotation.
- a stabilizing gyro in accordance with the invention could stabilize pitch 5 and roll deflections to a substantial extent.
- Figure 1 shows schematically a wind power station which iso provided with a stabilizing gyro according to the invention
- Figure 2 shows schematically a wind power station in an alternative embodiment.
- the reference numeral 1 indicates a buoyants wind power station including an installation 2 floating in the sea 4 and being moored by means of moorings 6.
- the installation 2 is provided with ballast 8.
- a drive shaft 10 projects vertically up from an electric generator 12, arranged relatively low in the installation 2, and0 up to a wind turbine 14 which is at a level above the installation 2.
- the drive shaft 10 rotates around a centre axis 16 and is supported in the installation 2 by means of an upper bearing 18 and a lower bearing 20.
- the drive shaft 10 is arranged to fol-s low the pitch and roll movements of the installation 2.
- a stabilizing gyro 22 in the form of a rotatable mass is supported around the drive shaft 10 by means of gyro bearings 24.
- the stabilizing gyro 22 is driven from the drive shaft 10 by way of a gear 26.
- the torque is transmitted to the generator 12 via the drive shaft 10.
- Some of the torque is transmitted by way of the gear 26 to the stabilizing gyro 22 which is given a relatively high speed of rotation.
- the stabilizing gyro 22 When a pitch or roll movement rotates the centre axis 16 out of its vertical position, the stabilizing gyro 22 will, because of a gyro's way of working, known per se, counteract this rotation.
- the stabilizing gyro 22 is placed relatively low in the installation 2, has a considerable mass relative to the total mass of the installation 2, has a relatively large radius, rotates relatively slowly and contributes to lowering the centre of gravity to a lower level.
- the stabilizing gyro 22 may be connected to the drive shaft 10, whereby the gyro bearings 24 and the gear 26 are redundant.
