Definitions
- the invention relates to an offshore wind farm or wind park comprising two or more wind turbines.
- offshore means any location on water, e.g., at sea, ocean or a lake, near shore or far offshore.
- buoyant foundations can be used, such as the WindFloat® system of the US company Marine Innovation & Technology.
- Figure 1 shows diagrammatically the calculated wake effect of a 5 MW wind turbine with a rotor diameter of 115 meter.
- the distance between an upstream wind turbine and other wind turbines at its leeward side should be sufficient to keep the wind turbines outside the wake area of the upstream wind turbine, so as to avoid a fall of energy conversion efficiency and undesirable loads, which may cause accelerated deterioration of wind turbine components.
- Figure 1 shows the wake area in case of an invariable wind direction. However, generally the wind direction varies. This results in an extended wake area and partial wake effects necessitating further spacing of neighbouring wind turbines.
- Wind turbines are generally provided with yaw systems allowing them to turn with the wind and to maintain an upwind or downwind orientation with every wind direction to maximize energy efficiency.
- the wake area turns with the yawing of the wind turbine.
- the distance between the wind turbines should be large enough in all directions.
- WO 02/073032 discloses an offshore floating wind power generation plant with a triangular float with a single point mooring system and a wind turbine on each of its corners.
- the float forms an equilateral triangle.
- the wind turbines have a parallel orientation. In wind direction, one of the wind turbines is at a distance from the other two. The distances between the wind turbines should be sufficiently large to keep the wind turbines at the leeward side out of the wake area of the front wind turbine. As a result, large floating structures must be used.
- the object of the invention is to enhance the energy yield of an offshore wind park of a given size.
- a further object is to provide a high yield wind park with wind turbines of a simple construction.
- the object of the invention is achieved by a wind park comprising at least one buoyant structure having two corners provided with a wind turbine and a third corner comprising a mooring section, wherein the third corner does not carry one of the wind turbines.
- the two wind turbines can stand much closer together than would be possible if a third front wind turbine would be present on the buoyant structure at a distance in front of the two turbines.
- the distance between the two wind turbines can be less than twice the diameter of the rotor blade area, e.g., about 1,5 times the diameter of the rotor blade area. Since the buoyant structure can be made much more compact, more wind turbines per surface area can be used and a compact wind farm with high turbine density can be realized.
- the distance between the mooring section and the wind turbines improves automatic alignment to the wind direction by weathervaning.
- the wind turbines each comprise a rotor with one or more rotor blades defining plane of rotation. Interference by turbulence is minimized if the planes of rotation of the wind turbines are within the same plane. If one or more of the wind turbines comprises a yaw mechanism to yaw over a certain angular range, the wind turbines can be positioned in such way that the planes of rotation are within the same plane when the wind turbines are in the central yaw position.
- the rotor blades define a plane of rotation, it is not required that the blades have parallel straight longitudinal axes.
- the blades may wholly or partially be curved, twisted and/or coned relative to the hub, if so desired. However, in the overall impression the blades will define a plane of rotation.
- the wind turbines can for example have a fixed orientation relative to the floating structure. In such case they do not need to have a yaw mechanism. Without yaw mechanism the wind turbine comprises less moving parts and requires less maintenance and repair.
- the buoyant structure can be rotated to position the wind turbines in an upwind or downwind position.
- one or more of the wind turbines can have a yaw mechanism allowing limited yaw motion, e.g., yawing over a range of about 20 degrees, e.g., about 10 degrees, to enable correction when in case of misalignment between the wind direction and the sea current the wind turbines move out of the wind direction.
- the structure can for example comprise a mooring section for mooring lines anchoring the floating structure to a sea bed.
- This mooring section can form a point of rotation.
- Turret mooring systems are particularly suitable.
- a turret mooring system is a mooring system where lines are connected to a turret which via bearings allows the buoyant structure to rotate around the anchor legs.
- Single-point mooring systems permit the buoyant structure to weathervane to the desired position.
- the structure may be provided with one or more drive units, e.g., one or more thrusters on one or more of the corners, for a more exact positioning of the buoyant structure.
- This can for example be desirable to compensate for current moving the floating wind turbines away from the optimum position relative to the wind.
- the turret can be a disconnectable turret, e.g., comprising a submergible mooring buoy that can releasably be coupled to the turret.
- a disconnectable turret e.g., comprising a submergible mooring buoy that can releasably be coupled to the turret.
- suitable disconnectable turret systems are the Riser Turret Mooring (RTM) system and the Buoyant Turret Mooring
- the use of a disconnectable turret system for mooring a floating structure carrying one or more wind turbine has the advantage that the buoyant structure can be disconnected and transported to elsewhere, e.g., for maintenance or repair or for temporal storage elsewhere to save it from expected extreme weather conditions, such as hurricanes. After disconnection of the submergible mooring buoy, it can be kept floating below sea surface level to prevent impact of wave motion.
- the buoy may carry the connecting end of the power cables connecting the wind turbines to a grid.
- the wind turbines will typically be of equal size, power, type and height. However, if so desired, different wind turbines can be used, e.g., wind turbines of different height.
- the wind turbines on the buoyant structure are positioned in a row in parallel arrangement.
- a third, fourth or further wind turbine can be present in a row with the wind turbines on the two corners of the buoyant structure.
- the planes of rotation of all the wind turbines should preferably be within the same plane if the wind turbines have a fixed orientation relative to the buoyant structure. If they have a yaw mechanism allowing yawing over a limited angular range, the planes of rotation of all the wind turbines should preferably be within the same plane when the wind turbines are in the central yaw position.
- the wind turbines can be configured to rotate in opposite directions.
- the wind turbines may for example have mirrored blade geometries or the rotor blades may have symmetrical rotor blade geometry. If more than two wind turbines are present, they may for example have alternating rotational directions. Alternatively, the wind turbines may be arranged to rotate in the same direction if so desired.
- the corners carrying the wind turbines and the third corner with the mooring section form a triangular arrangement.
- This triangular configuration can for instance form an equilateral triangle.
- the distance between the mooring section and a wind turbine can be larger than the distance between the two wind turbines or the distance can be less, if so desired.
- the buoyant structure as a whole will have a triangular outline although other shapes can also be used if so desired.
- the wind farm can for example comprise electrical equipment, such as a converter and/or transformer, shared by both wind turbines, the electrical equipment being located on or near the third corner, or a further free corner, of the buoyant structure.
- Other shared facilities can also be present on the buoyant structure, such as a helideck.
- a shared helideck has the advantage that with each flight two wind turbines can be serviced. The number of flights needed for maintenance of the wind turbines can substantially be reduced.
- the buoyant structure can have a center of gravity located at or above its center of buoyancy.
- the structure can for instance comprise three vertical columns and connection elements each connecting two of the columns.
- the columns can for example be semi-submersible to stabilize it for the impact of wave motion.
- the structure can have a submerged horizontal water entrapment plate attached to the lower end of each column, extending outwardly forming a section of a circle or a polygon around the base of each column, wherein the water entrapment plate area exceeds the cross-sectional area of the stabilizing column upon which it is attached, and wherein the water entrapment plate is supported by a plurality of radial beams each connected at one end to the base of the columns, and at the other end to the edges of the water entrapment plate, and transverse beams each connected at its both ends to the base of the columns and providing continuous support to the water entrapment plate.
- the buoyant structure comprises a deck attached to the upper ends of the columns, and/or it can be provided with walkways between the columns.
- the wind turbines typically comprise a tower carrying a gondola or nacelle with a rotor hub carrying a rotor with at least one rotor blade. Wind force on the one or more blades induces rotation of the rotor which is linked, e.g., gearless or via a gear transmission, to a generator, which can for example be located in the nacelle.
- the buoyant structure can comprise a buoyant substructure, a deck supporting minimum offshore facilities and / or an umbilical between the structure and possible subsea facilities beneath the buoyant structure.
- the substructure can comprise a plurality of vertical buoyant columns attached to a horizontal water entrapment plate at their lower end and to a deck that supports facilities at their upper end.
- the horizontal plate can extend radially from each column to cover the area formed by the center of the columns base.
- the buoyant structure can for example comprise further facilities such as antennas and other communication equipment to exchange information with a host platform, a helideck, storage and distribution systems, overnight accommodations for maintenance personnel, a crane or gantry to move equipment on the deck, a winch, or the like.
- the buoyant structure can be a column-stabilized unit with a large water- entrapment plate attached at the base of the columns.
- the submerged horizontal water entrapment plate can be designed to provide increased resistance to vertical accelerations and to roll and pitch rotational accelerations. Large amounts of water are displaced as the plate tends to move vertically. The mass of this displaced water is of the same order or larger than the mass of the buoyant structure.
- the total area of the plate is several times the cross-sectional area of the columns. The plate size and shape is adjusted so that it can compensate not only for heave, but also for strong wind force acting upon the carried wind turbines. This ensures that the motion of the buoyant structure remains small during normal operation.
- the plate can extend radially from each column forming a section of a polygon.
- the radial distance can be adjusted to control the natural roll and pitch period.
- the overall plate area is adjusted to control the heave natural period.
- no support to other parts of the hull is available near the plate outer edge, and therefore the water-entrapment plate must be cantilevered from the column.
- large structural supports are required to ensure the integrity of the plate and of its connection to the column.
- Such a buoyant structure is suitable to dampen wave and turbine motion, enabling wind turbines to be sited in previously inaccessible locations with strong winds.
- a suitable construction for a buoyant structure is for example disclosed in US 7281881, hereby incorporated by reference.
- Fig. 1 shows diagrammatically the slipstream of a single wind turbine
- Figure 2 shows in perspective a wind farm according to the present invention.
- FIG 2 shows a perspective view on an offshore wind farm 1 according to the present invention.
- the wind farm 1 comprises a buoyant structure 2 carrying two wind turbines 3.
- the wind turbines 3 comprise a tower 4 carrying a gondola or nacelle 5 with a rotor 6 comprising a hub 7 carrying three rotor blades 8.
- Wind force impinging the rotor blades 7 induces rotation of the rotor 6 which is linked, e.g., gearless or via a gear transmission, to a generator located in the nacelle, converting the mechanical energy of the rotor into electrical energy, which is fed into a utility grid.
- the rotor blades 7 of each wind turbine 3 define a plane of rotation. As shown in Figure 1, these planes of rotation of both wind turbines lay within the same plane.
- the wind turbines 3 have a fixed orientation relative to the buoyant structure 2 and do not have a yaw mechanism.
- the buoyant structure 2 has a center of gravity located above its center of buoyancy.
- the structure 2 comprises three vertical columns 10 in a triangular arrangement. Attached to the lower end of each these columns 10 is a submerged horizontal water entrapment plate (not shown) extending outwardly such as to form a section of a circle or a polygon around the base of each column 3.
- the water entrapment plate area exceeds the cross-sectional area of the stabilizing column 3 upon which it is attached.
- the water entrapment plate is supported by a plurality of radial beams each connected at one end to the base of the columns 3, and at the other end to the edges of the water entrapment plate, and transverse beams each connected at its both ends to the base of the columns and providing continuous support to the water entrapment plate.
- the three columns 10 form a triangle.
- the tops of the columns 10 form a deck 20.
- Two of these decks 20 carry a wind turbine 3.
- the deck 22 on the third corner 21 may carry shared facilities, such as a common converter or transformer used for both wind turbines and/or a shared helideck or the like (not shown) .
- the deck 22 on the third corner 21 is also used as a mooring section with a turret (not shown) for attaching mooring lines anchoring the floating structure 2 to the sea bed.
- the floating structure 2 can rotate around the third corner 21. Wind force will orient the buoyant structure 2 with the wind turbines 3 to an upwind orientation.
- the three columns 10 are linked by connection elements 23.
