Abstract
The invention relates to a directly driven interconnected windmill generator set, which comprises the long-distance monitoring computer, the tower barrel, the vane, the yaw system, the weather vane, the cabin electric control system, the tower bottom electric control system. The characteristics are: without the gear box the radial length of the set can be greatly reduced to solve the erosion, the noise and the wearing problems brought by the revolving of the gear box and to maintain the life span of the set and to protect the environment.
Description
Technical field
The present invention relates to a kind of direct driving wind power generator incorporated in power network group, belong to electrical generator fields.
Background technique
Renewable energy sources and new energy are the another kind of energy for conventional fossil energy, are important component parts of energy resource structure.By implementing the wind-power electricity generation of one of renewable energy sources and new energy hi-tech industrialization, can improve the capacity for technological innovation of wind-power electricity generation industry, for realizing renewable energy sources development and use amount, provide wind generating technology to support, promotion China's renewable energy sources and new energy technology and related industry continue, quick, sound development, and the wind energy turbine set that develops rapidly for China provides novel big capacity wind power generator incorporated in power network group reliable, with low cost.The enforcement of wind-powered electricity generation unit can advance the wind-power electricity generation industry process of wilderness demand, wind-powered electricity generation machine set technology comparative maturity, be widely used, market prospects are wide and can have induced effect to regional economic development.Quickening forms the industrialization basis of key technology innovation ability, through engineering approaches system intergration ability in conjunction with the advantage technology fields such as iron and steel, rare earth permanent-magnetic material, machining and control technique of China's characteristic.Promote the mixing together of renewable energy sources and new energy industry and related industry, promote renewable energy sources and new energy industry spur development model to market from government's leading type transformation, cultivation has the enterprise and the enterprise group of the strong market competitiveness, establishes the inherent mechanism that is beneficial to China's renewable energy sources and the long term growth of new energy industry.
At present, the main right and wrong of wind power generator incorporated in power network group directly drive the wind power generator incorporated in power network group, between the generator of non-direct driving wind power generator incorporated in power network group and the wind wheel step-up gear is installed, wind wheel is slow-revving, and generator is high-revolving, this type is because of being provided with gear-box, and wind-powered electricity generation unit maintenance amount is big, reliability is low, thereby the equivalence of wind-powered electricity generation unit utilizes the time low.
Summary of the invention
The purpose of this invention is to provide a kind of gear-box that do not adopt; the length of unit horizontal axis can reduce greatly; can effectively avoid problems such as the wearing and tearing of the loss, noise and the material that produce because of gear-box rotation even leakage of oil; make the operating life of unit more secure; also be more suitable in requirement on environmental protection, unit operation directly drives the wind power generator incorporated in power network group more stably.
The objective of the invention is to realize by following mode:
The present invention includes automatical control system under remote monitoring computer, tower tube, wind wheel, yaw system, weathercock instrument, cabin automatical control system, the tower, it is characterized in that: on the axle of wind wheel, be connected with one or more generator by mechanical coupled in series mode.
When the quantity of above-mentioned generator is separate unit, should adopt induction generator; When the quantity of above-mentioned generator is one when above, each generator adopts induction generator or synchronous generator all can.
Advantage of the present invention is: 1. owing to do not adopt gear-box, the length of unit horizontal axis reduces greatly, the mechanical transmission path of electrical energy production has been shortened, problems such as the wearing and tearing of the loss, noise and the material that produce because of gear-box rotation even leakage of oil have been avoided, make the operating life of unit more secure, also be more suitable in requirement on environmental protection; 2. avoided the maintenance and the replacing of gearbox parts, do not needed gear box lubricating oil and, thereby improved the validity of investment the monitoring of oil temperature; 3. because generator has big surface, and radiating condition is more favourable, the temperature rise in the time of can making generator operation reduces, and reduces the fluctuating of generator temperature rise; 4. can reduce the radial dimension of generator when the quantity of generator is one when above, change position of centre of gravity, be convenient to the general arrangement and the installation in cabin, make unit operation more steady.
Description of drawings
Fig. 1 is a structural representation of the present invention.Wherein: 1, air guide sleeve and wheel hub; 2, blade; 3, transmission shaft; 4, generator; 5, yaw system; 6, weathercock instrument; 7, tower tube; 8, remote monitoring computer; 9, boosting transformer; 10, automatical control system under the tower; 11, cabin automatical control system; 12, electrical network; 13, coupling.
Embodiment
With reference to accompanying drawing, the present invention includes automatical control system 10 under remote monitoring computer 8, tower tube 7, wind wheel, yaw system 5, weathercock instrument 6, cabin automatical control system 11, the tower, wind wheel is made up of blade 2, air guide sleeve and wheel hub 1, is connected with one or more generator 4 by mechanical coupled in series mode on the axle of wind wheel.Its concrete connection is to utilize the axle of transmission shaft 3 and coupling 13 and wind wheel to carry out mechanical coupled in series by generator amature, and consequently the axle of generator amature and wind wheel rotates synchronously.Directly driving in the wind power generator incorporated in power network group, when the quantity of generator is separate unit, should adopt induction generator; Each generator adopts induction generator or synchronous generator when above when the quantity of generator is one, comprises that magneto alternator all can.An application example is complete machine capacity 1.2MW, generator is 2,2 generator capacities are respectively 600kW, generator rotor shaft and wind wheel rotor axis mechanical coupled in series, 2 generator amatures and wind wheel rotate synchronously, 2 generator unit stators are installed on the engine room foundation by the antivibration cushion, and the electricity that generator set sent is connected to the grid in 12 by boosting transformer 9.
