Description
Affiliated technical field
The present invention relates to a kind of wind power station construction project mode of structure, especially be fit to the engineering structure mode that large-scale, super-huge wind power station is built.
Background technique
At present, existing wind power station construction project mode of structure is normally installed wind power generating set plane distribution formula on the ground.Because the mounting distance between the separate unit unit is generally all more than tens meters, tens square kilometres at least of the required site areas of wind power station more than total installation of generating capacity hundreds of thousands kilowatt, up to a hundred square kilometres at most.Therefore be not wind power station usually, and be wind energy turbine set.The wind-powered electricity generation set structure of wind energy turbine set generally adopts the horizontal axis structure, and present existing wind turbine fan blade wind sweeping area diameter reaches hundred meters, and the unit total height is then above hundred meters.In existing wind energy turbine set is built, enlarge the Basic Ways of total installed capacity scale, the one, by constantly enlarging site area to increase the installation quantity of unit; The 2nd, sweep the wind diameter by what strengthen wind wheel blade, increase the setting height(from bottom) of unit, improve the capacity of separate unit unit.Present wind energy turbine set construction project mode of structure exists many deficiencies:
1, can only utilize the wind energy in low latitude below 100 meters usually, the wind energy in relative high-altitude is difficult to obtain utilize more than 100 meters.And by known to the scientific observation, the wind energy energy in high-altitude will remarkable wind energy energy greater than low latitude below 100 meters relatively more than 100 meters.
2, the unit packing density is low, and has only utilized the space of the single level in ground.Owing to be subjected to intrinsic region area limitation, its development space is restricted.
3, present horizontal shaft type Large-scale Wind Turbines, fan blade to sweep the wind diameter huge, the height of tower tube also is difficult to high again.Will further increase the capacity of unit, technical difficulty is increasing, and it is limited to increase potentiality.
4, wind power generating set can only be utilized undiscipline and the indefinite wind-force of direction starts wind turbine, have relatively high expectations to starting wind-force, and wind-force is difficult to utilize when too big, and easily blower fan is damaged.
5, generator set plane distribution formula is installed in tens to the ground of hundreds of square kilometre, and is far apart between the unit, and it is big that electric power netting twine link cost height, electric power collect in the process loss.Because unit is distributed on the vast and bare open country, brings difficulty to management maintenance, maintenance cost increases.Equipment moves in the open air, and affect adversely working life.
Summary of the invention
In order to solve the not enough problem that exists in the present wind energy turbine set construction project mode of structure, the present invention proposes a kind of new wind power station construction project mode of structure.This mode is: at the regional architecture that meets the wind power station construction condition dam that keeps out the wind, wind energy is implemented interception assemble.Dam is rearranged by several same dam body and airway.The clearance space of constructing according to Demand Design between dam body and the dam body is the airway, and the wind energy of being assembled by the dam body interception is current along the airway.The dam overall appearance is the pectination type, and single dam body outward appearance belongs to the middle shuttle shape type that belongs to cuboid of triangle body for two, front and back, and the airway is imported and exported and is bell mouth shape.In the dam body is the frame structure space of some floor heights, the space is used to install the perpendicular axis type wind-driven generator group in the dam, wind turbine component wherein is installed in the edge in next-door neighbour airway, make wind wheel blade stretch out dam body outer to the airway wind-engaging, the wind energy that is blocked gathering is along the airway when current, drives wind turbine and drives generator for electricity generation thereby wind-force acts on wind wheel blade.The right and left is respectively adorned a row on the aspect of generator set in single dam body, and some of every rows have several layers from top to bottom; Be three-dimensional distribution mode on the whole from top to bottom, from left to right, from front to back.This construction engineering structure method of windshield dam type wind power station mainly contains following advantage:
1, by the construction dam that keeps out the wind, wind power station construction project mode of structure is developed to the high-altitude by ground, change to solid, can the wind energy in relative high-altitude be used, expand the development space that wind-powered electricity generation is built by the plane.
2, by the construction dam that keeps out the wind, the wind energy of undiscipline can be assembled, the unsettled wind energy of direction is guided, make more weak wind be converted into stronger wind, can under the condition of less wind-force, be started wind turbine, can be improved the utilization ratio of wind energy.
3, by the construction dam that keeps out the wind, the installation of wind-powered electricity generation unit can be adopted three-dimensional distribution mode, can make full use of the space, improves the packing density of unit, for enlarging total installation of generating capacity, builds large-scale, super-huge wind power station and creates conditions.
4, by the construction dam that keeps out the wind, the wind-powered electricity generation unit can be installed concentratedly in the space in the dam body building, and equipment helps the maintenance management of equipment in indoor operation, can reduce maintenance cost, the working life of prolongation unit.Can realize three-dimensional high density distribution mode because unit is installed, it is short that the electric power netting twine connects distance, can reduce engineering cost, reduces the electric power line loss.
5, the generator set that is installed in the dam body adopts the perpendicular axis type structure, wind turbine blade can adopt choke formula blade, can avoid present horizontal shaft type wind-powered electricity generation unit commonly used oversize because of wind turbine blade, unit is installed the too high technical development obstacle that brings of tower tube, makes the more jumbo generator set of design become possibility.
