Description

MEGA WIND POWER PLANT
The invention provides for large scale utilization of the power contained in the wind.
The most conventional method of utilizing wind power is the wind power station, in which a three-blade rotor connected to an electricity generating generator is placed on top of the tower. The height of the towers are generally between 20 - 50 m and the generators are 30 - 500 kW.
Wind power is generally expensive compared to other forms of power production. The reason for this is the utilization of the lower air layer winds at 20 - 50 m, which contain little power compared to higher air layers at 50 - 200 m. The price of the produced energy is also increased by the fact that the yield of one wind power station has to cover the erection, tower and power transfer costs of the station. The area demand per power station of individual power stations (recommended location dispersion approx. 250 m) is a big cost raising factor of the produced energy and affects essentially the availability of wind power. The gained operating efficiency MWh,a/m2 of known wind power stations is low.
Known equipment utilize only part of the power produced by the rotor revolution area, especially at more power containing winds of 10 - 25 m/s. Fig. (5) shows the importance of the wind power station location for the generation of power.
Fig. (6) presents with the curve (a) the intersection of the power generation at the place of the generator nominal output, the curve (b) shows how steeply the unutilized energy content however grows when the wind force increases. Wind power stations are generally operating up to 25 m/s, when the strain of the wind becomes so big that the station is stopped.
The invention provides such a high electric energy production from one station unit that the price of the power becomes more profitable than wind power produced by conventional methods. Due to the invention the wind power becomes competitive also compared to other electric energy production methods. The invention enables to consider the wind power as a basic power source based on the price and availability of the power. When the clean wind power is further compared with hazardous waste and release disadvantages of other power production forms, the advantages of the invention can be considered as remarkable.
The invention is described below with reference to the enclosed drawings:
Fig. 1 presents a front view of the form of embodiment of the mega wind power station (1) having three towers (3) . The parts of the wind power station are the wind power unit (2), the tower (3), the support levels (4), the guy wires (5), the base (6) , as well as the erection and maintenance crane (7), the siting carrier (8) .
Fig. 2 shows a top view of the embodiment according to fig. 1. The fig. shows the base of the power station (1), in which the towers (3) are placed m a triangle form in order to achieve a stable construction and also a minimum of covering and shadowing when the wind direction changes. Generally, when there are more than two towe s (3), the mutual location form of the towers (3) is close to a regular polygon, in which the amount of points is equal to the amount of towers (3) . The station is generally placed w th the concave side against the prevailing wind. The station is founded m the basement rock. Concrete and sea climate enduring steel are used as construction materials .
Fig. 3 presents the siting carrier (8) with which the wind power unit (2) is attached to the tower (3) . The rotor (9), the gears (10), the generators (11), the tower (3), the collar (12) on which the carrier is supported in the tower, the support structures of the siting carrier (8) damp the vibration of the rotors, the rotation gear (14) of the siting carrier.
Fig. 4 presents a form of embodiment of a mega wind power station (1) with only one tower (3) , provided with a wind power unit (2) located on standard height and movable in the vertical direction (16), the guy wire (5), the tower (3) as well as the erection and maintenance crane (7), the siting carrier ( 8 ) .
Fig. 5 shows the average wind power content at different heights. The bar (a) depicts the area utilized by known power stations. The bar (b) depicts the area utilized with the assistance of the invention.
Fig. 6 presents the power production of a wind power station. Curve (a) depicts the production of a known station. The Curve (b) depicts the power utilized with the assistance of the invention.
The mega wind power station can comprise several towers (3) and the height of the towers (3) can reach over 200 m. Wind power units (2) are placed on top of each other m the towers (3), and the amount of units depends on the required effect of the station, the diameter of the rotor (9) and the height of the towers (3). The new accommodation enables the utilization of the bigger energy content (fig. 5) of the higher air layer. The gained operating efficiency in relation to the ground area MWh,a/m2 is far better than for conventional wind power stations .
The wind power units (2) are attached to the tower (3) on top of each other with a special siting carrier (8) . The generators (11) and the gears (10) are accommodated m the carrier (8) so that balance is obtained. The power generated by the rotors (9) is transmitted with the gear (10) to the generators (11). More than one generator is preferably used m the wind power unit (2) . The generators can have different nominal outputs. The energy content transmitted by the rotor (9) determines the use of the generator (11). At strong wind, two generators (11) can be in use, when they can more effectively utilize the energy quantity transmitted by the rotor (9), thus optimizing the electricity generation at several different levels of wind force.
The mega wind power station comprises several towers (3) m order to achieve a sufficient height and stability. The invention is characterized m that several wind power units (2) are provided in the same tower (3) . One special feature of the invention is the siting carrier (8), with which the wind power unit (2) is attached to the tower (3) and can be turned against the wind when the wind direction changes.
The invention provides for the utilization of the bigger wind powers prevailing in the higher air layers of 50 - 200 m (fig. 5) . The big electric energy quantity produced by the station unit provides a competitive price level for the electricity generated. The invention functions as follows:
The anemometers control the force and direction of the wind. All wind power units (2) are computer controlled. At gentle wind the rotor (9) rotates a small generator m the wind power unit (2) and when the wind force increases, a bigger generator. At strong wind both generators are in operation. The effect of the power station can thus be optimized at several levels close to the wind energy level utilized by the rotor. When the wind reaches a speed of 25 - 30 m/s the power station is stopped.
At gentle wind the rotor (9) would not be able to rotate a big generator and at strong wind a big part of the energy utilized by the rotor would be wasted when using a small generator .
The station is dimensioned according to local conditions and the required electric energy production objectives. Variable parameters are e.g. the height of the towers (3), the amount of wind power units (2) , the sweep area of the rotors (9) and the outputs of the generators (11) .
The mega wind power station can also be a station comprising one tower (fig. 4) .
The station can also be implemented as a regulation version, in which each wind power unit (2) can be lifted and lowered according to the wind force. At gentle wind the wind power unit (2) is lifted to the top of the tower (3) thus reaching the better winds higher up. At strong wind the lower air layer is sufficient to generate the power required by the generators.
The station can be provided with support guys (5), which are planned for each case separately. At the upper and support levels (4) can be installed an erection and mainte- nance crane (7) moving on rails. In the embodiment comprising one tower (3), the erection and maintenance crane (7) is at the top of the tower (fig. 4) .
