Abstract
The invention relates to a construction scheme of a vertical axis wind wheel power horizontal transmission system and a wind power plant, belongs to the field of wind power generation, and aims to solve the problems that the conventional wind generating set has a complicated structure, multiple faults and poor wind resistance, and is difficult to install and maintain. The construction scheme is characterized in that: power generated by the combined rotation of N (more than two) wide and large vertical axis wind wheels is transmitted horizontally instead of vertically through the transmission of a gear box, and transmitted to a generator plant in a step-up mode through the gear box, so that N (one or more) high-power generating sets operate to generate electricity. In the scheme, wind is taken from high altitude, wind power is cohered in one shaft, and the electricity is generated in a ground plant; the vertical axis wind wheels are arranged in the maximum density, the distance between two wind wheels is N meter, and the normal operation of a maintenance machine is not influenced, so that the wind power resources of the conventional high-quality wind field are fully utilized; and the number of the installed vertical axis wind wheels per square kilometer, and the installed capacity and generating capacity of a generator in the plant are dozens of times or even higher than those of the conventional wind field with the same area.
Description
Technical field
The present invention---construction scheme of vertical axis rotor motivation level transmission system and wind power plant belongs to renewable energy sources---wind power generation field.
Background technique
Present existing wind power generating set has two kinds, and a kind of is the wind power generating set of horizontal shaft type, and a kind of is the wind power generating set of perpendicular axis type.Powerful wind power generating set (MW class) is still based on horizontal axis.Its require to have a tall and big vertical tower, the top of pylon be equipped with can 360 degree rotations generator, impeller produces rotation under the effect of wind-force, drives generator for electricity generation by horizontal axis.This wind-driven generator structure complexity, technical requirements height, installation and maintenance inconvenience.Because wind direction is indefinite, the wind sweeping area of blower fan is a circle, does 360 degree rotations around vertical tower again, and the blower fan floor space is big.Be not less than 3D according to distance between the colleague of country's " generator set of the wind power plant designing technique standard " wind power generating set, distance is not less than the regulation of 5D between row and the row, the pylon limited amount of every square kilometre of setting, and electric motor power is low.Because blower fan is heavy, the pylon height, wind loading rating is poor.Cause that gentle breeze is not worked, strong wind full cut-off machine, the wind field wind resource is not fully used.The electric wave that produces when the large size installation of blower fan pylon and the generator work on pylon top produces aircraft radar, TV signal, signal of communication and disturbs.The powerful manufacturing of horizontal axis at present is near the limit of current material level and Economy price ratio, and development space is limited.
Vertical shaft wind power generator structure is simple relatively, can adapt to any wind direction, and setting height(from bottom) is low, and operating noise is little, and it is low to start wind speed, installs easily and keeps in repair.Shortcoming is that separate unit wind-power electricity generation acc power is little, and efficient is low, and main shaft easily causes resonance, and difficulty etc. is incorporated into the power networks.But vertical axis aerogenerator will become an important directions of large fan technical development.So vertical axis aerogenerator more and more is subject to people's attention in recent years.The power of vertical axis aerogenerator group does not all reach MW class at present.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of brand-new " construction scheme of vertical axis rotor motivation level transmission system and wind power plant " with the contradiction that solves existing wind generating set structure complexity, fault is many, installation and maintenance are difficult, wind loading rating is poor, cost height, electricity price cost remain high.Its characteristics are: rotate the power that is produced by the N more than two wide in range and tall and big vertical axis rotor combination, become horizontal transmission through gearbox drive by vertical transmission, again through the speed-changing gear box step-up transmission to the generator factory building, make the N platform high-power generator group running generating more than 1 and 1.Make wind energy power have stability, reliability and controllability.
This scheme is that wind is got in the high-altitude, and cohesion wind-force generates electricity in the surface facility in one.Vertical axis rotor adopts the layout of maximal density, and the distance between two wind wheels is a N rice, only otherwise influencing the servicing machine normal operation gets final product.The wind resource of existing high-quality wind field is fully utilized.It is tens times and even higher of the same area of existing wind field that every square kilometre vertical axis rotor is installed in quantity, the factory building generator electric motor power and generating capacity.The ideal that makes the absorbed costs of wind-powered electricity generation be lower than the incomplete cost of thermoelectricity is achieved.Provide brand-new thinking for making ten million multikilowatt wind-powered electricity generation factory, made wind energy become one of the most competitive forms of electricity generation.
This scheme overall structure is simple and direct, wind-powered electricity generation conversion efficiency height, low cost of manufacture, maintenance needs is low, can satisfy any construction scale, carry out on a large scale in any places such as suitable sea, seabeach, Gobi desert, desert, lake, marsh, mountain region, level land, the construction of big capacity wind-powered electricity generation factory, also can do the construction of step wind-powered electricity generation factory.This scheme can realize that the maximization of the high-power ability of exerting oneself design of vertical axis rotor unit and generator power designs both combinations.Its vertical axis rotor and wind power generating set are oversimplified, and function is brought into play separately.The overall structure imagination of its original creation, principle, method, wind wheel are the correct direction of wind energy power to high-power, big capacity, batch production, intensification design object with combining of power plant.
Because vertical axis rotor is tall and big, and intensive again installation can play the effect of wind prevention and sand resistance, is the barrier of forever defending and controlling sand of one projection, has the function of comprehensive environmental improvement again concurrently.
