The invention relates to power, namely the power plants that convert the kinetic energy of the wind flow into other forms of energy, and can be used in industry, housing and communal services or as a stand-alone energy source.

The prior art various technical solutions, wind turbine having a multi-module design with the use of vertical axis turbines (or with vertical axes of rotation). The modules include blocks with stators, playing the role of guide vanes for wind, and the rotor converts the energy of wind into rotational motion of their shafts. Known and different solutions blades or vanes, as well as of the rotors used in these devices, such as blades having a profile type Daria, the Savonius rotor, and combinations thereof, and so on

In particular, the known wind power plant (WPP) (patent EA 003784 B1, IPC: F03D 3/06), in which wind power units (WEA) include one or more cylindrical blocks arranged in series vertically, each of which includes a stator with a concave-convex plates and the rotor with convex-concave blades connected to common to all the units of the vertical shaft, the lower end of which is connected to the rotor GE is erator. All blocks rotors have a constant outer diameter, the number of blocks in the unit is 1-50, depending on the height of one block and wind conditions, and between blocks in WAA there are gaps, provided with an annular conical roofs. When the rotors of all blocks contain the same number of blades. On WAA installed multi-pole brushless DC generator with automatic regulation of excitation to provide a constant voltage when the change of wind energy and use of energy short-term wind gusts, storms and hurricanes. In addition, via has the power management mode of the generator, including the regulator output power of the generator to ensure the rated rotor speed within the specified range.

However, due to the fact that the wind speed at different heights from the surface of the earth has different meanings, blocks WAA installed at different heights, develop different capacity. Blocks located in the lower part of the unit, can develop less power, and at common shaft with the upper blocks with a higher speed, can move in the fan mode, rotate the upper blocks, which reduces the output power of WEA. If necessary, increase the power of VEA increases the diameter of the stator and the rotor is, which leads at the same wind speed to reduce the frequency of rotation of the rotor, and applied in such circumstances, low-speed generators must have large dimensions and weight. In addition, the design of this setup is the stator, which contains, as a rule, more than half of the weight of the whole structure.

Known petroenergoleasing (utility model RF # 86672, IPC: F03D 3/04) containing at least one power module, executed with a possibility of vertical installation of additional power modules over principal and comprising performed with a vertical axis of rotation of the rotor is formed attached to the supporting cylinder blades located inside of the stator formed is made coaxially with the rotor stationary system of vertically arranged metronapoli plates, and connected with a bearing cylinder main power node, located in the lower part of the main power module. Petroenergoleasing also contains at least one associated with bearing cylinder for more power node, one of which is installed in the upper part of the main power module and the other is installed in the lower and upper parts of each additional power module, with the primary and secondary power shall nodes each made in the form of distributed magnetoelectric generator. Each petromarula plate provided associated with the speed control of the rotor movable sector established with the possibility of a telescopic change of its area, the rotor blades are made flat and provided with a swirler made in the form of curved strips, and the placement of the rotor blades relative to the rotor cylinder is made with the formation along the ground between them and the bearing cylinder of the diffuser.

However, the above disadvantages are characteristic of the present technical solution.

Known wind power unit (VAU) (RF Patent for the invention №2352809), comprising a frame, a wind turbine, containing two cylindrical block vertically on the same geometric axis and separated by a lid frame, each of which has a guiding apparatus for the incoming air, which is the stator of the turbine, with the plates to trap the wind and the rotor blades connected to the shaft for converting wind energy into rotational motion of the shaft, an electrical multi-pole brushless alternator with a rotor having a brush site, with the stator and automatic control systems. While the stator of the brushless generator is made to rotate in the direction opposite to the direction of rotation of the rotor and provided with a Central the output tubular shaft, and the rotor has a Central shaft running inside the tubular shaft of the stator. Each unit of a wind turbine consists of tiers separated by transverse disks, each tier has a guiding apparatus - stator plate which is planar and installed radially, and the rotor blades which are connected to the shaft of the unit. The tiers are the lower and upper groups, United by a common shaft mounted coaxially, the shaft of the lower group of tiers is made tubular and is connected to the shaft of the stator of the brushless generator and the shaft of the upper group stages takes place inside the tubular shaft of the lower group of tiers and connected with the shaft of the rotor of the brushless generator, blades, rotors tiers lower and upper blocks installed with opposite angles of inclination to the radius of the rotor, to ensure mutually opposite directions of rotation of the rotors of these blocks, the group stages of a wind turbine, rotating the rotor of the generator, and the group stages, torque stator of the generator are run according to their estimated capacities.

This wind power unit made in the power frame, which gives the reliability and stability of the structure as a whole. However, the design uses a low speed rotor speed is less than 1 and creates a small swept surface. The increase in the surface in the Anna design will inevitably lead to an increase in its size and weight and, as a consequence, problems of installation and transportation.

Known also two versions of the wind to even with large utilization of wind energy (KIEV).

In particular, is known for combined wind power module consisting of two rotary units - internal and external, are mounted on the same axis and connected to the generator unit (CN Patent No. 201255083 (Y), IPC: F03D 9/00).

The indoor unit is a multi-tiered Savonius rotor, outer made of blades Daria. Known combined wind module in which an external unit also consists of blades Daria, and the inner is made bunk, with tiers formed by cylinders of different diameters using straight blades (application for invention of Japan No. 2003314432).

However, used in constructions there is no power frame for fixing blocks, which reduces the reliability and stability of the whole structure during its operation on the ground under the influence of wind loads.

Known wind power installation (CN Patent No. 201391420 (Y)), which represents a set of wind power modules arranged in a vertically oriented security framework installed on the stretch marks. Modules include internal and outside of the deposits of the blocks, the last of which is composed of blades Daria. This mounting of the blades Daria to the axis is provided through additional force elements which rotate together with the whole design. Each power element contributes to disturbance in the flow of the wind, which dramatically reduces the utilization of wind energy.

Closest to the claimed solution is wind generator (patent Application KR №10-2010-0123985), including wind power module mounted in the power frame, which is a set of four racks interconnected by transverse rods. The module includes internal and external blocks, converts wind energy into rotation of the shafts on which they are installed, connected to the generator unit. The external unit consists of four blades Daria located at the same distance from each other and having a convex profile of the outer surface and straightened internal. The indoor unit is composed of blades, a profile which resembles the profile of the blades Daria mounted on the cylindrical part with the lower and upper base, through which the fastening of the unit to the pin elements, through which rotational energy is transmitted to the generator site. In this case, the generator unit consists of two generators, one of the n of which by a belt connected to a pulley of the internal block, and the second pulley of the outer block.

This design is characterized by a higher utilization of wind energy by providing independent rotation of the inner and outer blocks. However, this setting does not increase capacity by adding additional modules. This design does not provide sufficient durability and reliability. In addition, this design does not provide counter-rotation of the inner and outer blocks.

The objective of the invention is to provide a modular wind energy center (WEC) with a vertical axis of rotation, which increases the utilization of wind energy (KIEV), characterized by a specific generation of at least 1 kW of installed capacity of the generator on each module, while simplifying the structure and the ability to assemble modules in a column in the construction of multi-modular wind energy systems without the use of special lifting equipment.

The technical result is to increase KIEV, the ability to produce electricity in a wide range of unstable wind loads and improve reliability of the operation of the entire installation. Performance of a complex set of modules, and the modules themselves of collapsible blocks and parts ensure the leads to a significant simplification of transportation, as well as the construction of the complex in hard to reach places.

The problem is solved by the fact that wind energy complex includes at least two wind power module, located one above the other, each wind module contains enshrined in the security framework of internal and external wind blocks, placed on the same axis and configured to rotate and transfer the energy of rotation of the generator, while the inner wind block represents the body, predominantly cylindrical shape, the side walls of which are mainly formed by the blades having a shape and location that enables the rotation of the housing under the force of the wind, and the external wind block includes at least two blades Daria located at the same distance from each other and fixed to the internal elements of wind power block, with two wind of the module is made with the possibility of placing the generator node between them, internal and external wind blocks of one of the module is made to rotate in one direction and connected to the generator rotor and the inner and outer wind blocks of the second module is connected to the stator of the generator, the power frame represents at least three hours, soedinenii a transverse elements from the upper and lower walls of the casing internal wind block, this rack power cage one module configured to connect with struts framework neighboring module.

In addition, the domestic wind power unit can be made possible through its Central axis, while the axis of the inner and outer blocks wind made tubular. EEC may have dimensions determined by the dimensions of internal and external wind blocks, which have a ratio of cross sectional dimensions 1:1,3-4.

In addition, the blades of the inner wind of the block have a profile that is characterized by the presence of the concave part from the inner surface and the convex - side outer surface. Blades can be made in the form of curved plates with an estimated radius of curvature.

Domestic wind power unit may be provided with transverse structural members, which divides the housing into tiers, with power elements are located between the upper and lower walls of the housing. Transverse load-bearing elements and/or the upper and lower housing wall of wind power unit is made with the possibility of permanent connection with the blades, while the transverse load-bearing element and/or the upper and lower housing wall provided with a slot or groove, the shape of which provides interfacing with the relevant part of the scapula. Cross silove the elements and/or the upper and lower housing wall of the inner wind of the block represent the disc or ring elements, stiffeners. A possible embodiment of the transverse load-bearing elements and/or the upper and lower walls of the casing of wind power unit in the form of annular elements arranged coaxially in the same plane and connected by a radial connecting elements. Blades of adjacent tiers of the domestic wind power unit can be located with an offset step, the value of which is equal to 0.3 to 0.8 of the distance between adjacent blades of one layer on the outer periphery of the circumference of the body. In addition, the blades can be set at an angle of 30-70° to the radial line passing through the outer edge of the scapula. Each tier of the blades are arranged relative to each other at a distance equal to or greater than half of its chord. This blade internal wind block, forming its lateral surface, can be formed from a single sheet of metal or plastic by extruding the profile of the blades with the subsequent cut around the perimeter of the blade on three sides, after which the workpiece blades are bent at a given angle, and then the sheet is rolled into a cylinder and connect the free ends of the bent blades fasten the ring of power elements.

In addition, the blades Daria in the EEC can be fixed to the upper and lower walls of the casing internal wind block. Blades Daria made the possibility of movement in the transverse direction from the Central axis, for example, through the use of a telescopic mechanism.

EEC also includes generating a node, which may consist of individual generators, the number of which is determined by the number of modules used, the generators are located under the appropriate module and configured to connect to an external cable.

Improvements also apply to the power frame. Rack power cage made protruding from the plane of attachment of the transverse connecting elements with the possibility of connection with struts framework neighboring module. The power frame is provided with elements for the mechanism of manual lifting modules and installation on site, and devices for fastening elements stretch and drives braking during the process works.

Wind energy center (WEC) is a mostly modular collapsible design (Fig.1-6). While the installed capacity of one module is not less than 1 kW. A possible variant is a complex operation with a single module. Module 1 EEC is combined and consists of a fixed power frame 4 of the inner 2 and outer 3 wind blocks, placed on the same axis 8 and is made to rotate and transfer the energy of rotation through the axis of the generator node 11. The inner 2 and outer 3 wind power units can be placed each on its own axis 9 and 10, with the possibility of rotation of the stator and rotor of the generator node, respectively, when the axes are located one inside the other. Mounting blocks 2 and 3 axes are designed to ensure their counter or unidirectional rotation. Options dependent and independent internal rotation of the power unit from the outside (through advancing ratchet mechanism mounted on a through shaft (axis) passing inside the walls of the inner blocks wind and torque generator).

Such modules 1 may be a few that are installed one above the other. The number of modules depends on the desired consumer power. The modules can be interconnected by means of a flange connection or any other connection. Axis 8 of the adjacent modules 1 can be interconnected by couplings.

Internal wind block 2 is a rotary wheel or housing 5, a predominantly cylindrical shape, the side walls of which are mainly formed by the blades 6 having a shape and location that enables the rotation of the housing under the force of the wind. The blades 6 are internal and external profiles, providing the module rotation under the force of the wind pressure on the inner profile and the lifting force on the outer profile, and the inner profile has a concave portion, the outer convex. The blades 6 can be made in the form of curved plates. When the bend radius is selected as the creation of the airfoil. Internal power unit is located at the height of the cross-power elements 12, which divides the block into tiers and is made in the form of discs or annular members with the opportunity detachable connection with the blades 6. When this transverse force elements 12 are provided with slots or grooves to accommodate blades 6 which form on especial their mate with a corresponding part of the blade 6. The scapula is also fixed on the top 13 and bottom 14 walls of the casing 5. The blades of adjacent tiers can be located with an offset step, the value of which is equal to 0.3 to 0.8 of the distance between the blades on the outer periphery of the circumference of the body (i.e., the outer contour of the power element drive). In addition, for maximum use of wind energy blades are rotated about their vertical axis passing through the edge of the blade located near the outer perimeter of the upper and lower sides of the chassis or power elements, and the second edge facing toward the Central axis of the block, and the angle between the blade and a line passing through the axis of the block and the first edge of the cross-section is 30-70°. In other words, the blades are at an angle of 30-70° to the straight line connecting the center of the disc and the point of attachment of the blades on the edge of the disk (the disk radius).

The number of blades is calculated depending on the prevailing wind speed at the installation site, EEC, and also depending on the length of the circumference of the body 5. The number of blades is determined by the distance between them, which must be not less than one-half of the chord. Internal wind block 2 may be formed from a single sheet of metal or plastic. In the case of manufacturing the chassis with blades made of plastic sheet blank is formed into the od pressure to give the specified profile blades with a subsequent cut (cutting) around the perimeter of the blade on three sides. Then the cut blanks blades are bent to the desired angle, after which the sheet is rolled into a cylinder and fasten or weld. The free ends bent blades for durability can be further bonded transverse structural members 12. In the production version of the chassis with blades of sheet metal is first cut on three sides, the profile of the blades, and then bent at a given angle, then give the desired rounded shape of each blade with the specified radius of curvature.

Top 13 and bottom wall 14 of the housing 5 can be made continuous with the ribs or in the form of a set of two or three annular elements arranged coaxially in the same plane and interconnected radial elements.

External wind unit 3 includes at least two blades Daria 7, located at the same distance from each other, which can be mounted either on the internal elements of wind power unit (for example, on the top 13 and bottom 14 walls of the casing 5 internal wind block 2, or on the axis of the block), and on a separate axis. Optimal performance of external wind block is a variant with three blades Daria. The shape of the blades Daria can have both curvilinear and rectilinear profile along the length of the blade (the IG.1, 2). High aerodynamic parameters characterized the blade Daria having an asymmetrical cross-sectional profile when the linear dimensions of its convex part exceeds the linear dimensions of the concave or rectilinear part. Blades Daria can be made extensible in the transverse axis direction to control the power withdrawn. To do this, they can be provided with a telescopic mechanism (not shown). To regulate the speed of rotation of the block blades Daria can be made with the possibility of changing the angle of attack to the oncoming wind flow. This unit is equipped with a control mechanism, located at the place of attachment of the blade to traverse. External 3 wind block is made with transverse dimensions greater than the transverse dimensions of the inner wind of the block 2 is more than 1.5 times.

The inner 2 and outer 3 wind blocks fixed in the power frame 4, which is also a team of construction. While the structural frame includes at least three hours 15 interconnected by means of transverse elements 16 from the top 13 and bottom 14 walls of the casing 5 of the inner wind of module 2. The rack 15 is exposed beyond the plane of the transverse mounting elements 16 to provide connectivity (implementing the program) with racks adjacent module using known mounting assemblies. The structural frame can be equipped with special mounting blocks, providing the possibility of manual lifting and installation of the modules on site, as well as devices for fastening elements stretch. Each module is equipped with a brake mechanism with the output from the rope to the base of the EEC. The structural frame can also be made with the possibility of changes in transverse dimensions, using, for example, the built-in cross-connection element frame telescopic mechanism.

In the inventive EEC can be used a standard generator with fasteners to the power frame, providing the opportunity for counter-rotation of the stator and rotor, and/or used standard serial high-speed generators attached to the axis through the multiplier. Generating the node 11 can be part of each module, and the modules are interconnected mechanically with the location of the generator nodes between them, and the conclusions from each generator node is configured to connect to an external cable. A possible embodiment of wack with the use of a generator node. For option two-module design, the modules which are made with the possibility of counter-rotation, the optimum location of the generator node between them. Option strachn the th rotation can be performed within a single module on a similar principle counter-rotation of the inner and outer blocks, transmitting through a separate axis of rotation, the stator and the rotor of the generator.

EEC may be further provided with a platform for integrating the generator node and modules (see Fig.6). The platform can be equipped with manual or electric hoist, to enable the lifting and installation of the modules (if necessary increase the capacity of wind power complex) without the use of special lifting equipment and can be performed on the supports with the ability to change the height and lateral dimensions. The top module of the complex is equipped with a cover or sealing element preventing the ingress of moisture into the zone of attachment of the bearing Central axis.

EEC can be provided with an e-node modular layout, providing protection against overdischarge and overcharge of the rechargeable batteries, the current protection of generator parts, brakes design in stormy winds, disabling the oscillator when the storm winds. Modular layout allows to increase the output power if necessary by adding standard modules to the base unit. The online site includes charger, controller, control system with limiter function power inverter, diagnostics and data transfer to a remote user on various the communication channels, the power management mode of the generator, including the regulator output power of the generator to ensure the rated rotor speed within the specified range.

The structural frame of the EEC may be made of metal, the blades of the inner block and the blade Daria - made of composite materials. Modules EEC, as well as other structural elements of the complex may be joined together using threaded, riveted, welded, etc. connections. You can also use quick couplings (castle). Such compounds are well apply to mobile complexes, which during operation is repeatedly assembled and disassembled (install the stand-alone power remote construction sites, and so on).

The complex is assembled from one or more modules, while schematically Assembly of the module shown in Fig.3. Integral power the entire complex is set by the number of units used. The geometry of the complex may be different, depending on the problem being solved. All rotating inner 2 and outer 3 wind blocks mechanically connected with the shaft of the generator node 11. For energy conversion is an important parameter is the speed of rotation of the shaft of the Converter (for rotating machines). In this regard, in some cases it is advantageous to use a multiplier, uvelichivali the speed of rotation. But any multiplier introduces additional losses, so it is important to select the design of the multiplier, which have the least number of losses.

EEC is as follows.

Wind, falling on the blades 6 of the inner wind of the block 2, and the blades Daria 7 external wind block 3, leads them into rotation. Through the axis on which are fixed blocks, the energy of their rotation is transmitted to the generator node 11, which generates energy and transfers it to load.

The effect of increasing the energy conversion efficiency due to the following. Due to selection of the geometry of the modules can be taken into account the spatial heterogeneity of the wind. The complex of the claimed design ensures the effective operation mode for each thread. The active area of each independent module - internal and external, to differentiate the flow of air. The installation allows you to choose for her efficient mode of operation, and the total for all items for the entire installation to include more spatial power spectrum of the wind.

A specific example. Was manufactured EEC, with a height of 6 meters, consisting of two modules with the diameter of the inner block is 0.5 m, 2 m Power module is at rated wind speed of 1 kW. When the coefficient used is of wind energy 35% and wind speed of 11.5 m/s power EEC is 2 kW (speed not more than 300 rpm). The number of blades Daria - 3, located at an angle of 120°, the profile of the blades nasa 0015, number of blades - 18 with the chord length 10 see the Installation angle of the blades is 30°.

Collapsible module-independent structure of the complex increases its integrated reliability and stability: when the failure of a module or module unit, partially or completely, the complex as a whole does not lose health. In addition, implemented it a modular design simplifies the design and makes it easy to increase its total capacity, and also simplifies transportation and installation of the complex. In addition, the operation of the wind farm does not depend on wind direction, it is resistant to sharp his impulses and requires minimal space for installation.
