Blower fan and wind-driven generator all are located in the same housing 2.Its use is summarized as follows: when blower fan towards the wind-driven generator air draft time, wind-driven generator rotates, after changing into electric energy by wind-driven generator, part wind energy flows to storage battery by electric control system, by storage battery electrical power storage is got up, simultaneously, electric energy by after the inverter inversion boosting to mains supply.
Related application of the present invention and principle are described as follows.
The feature of the inventive method is that artificial wind devices and wind power plant are fused by custom-designed bindiny mechanism, the wind generating that wind power plant produces by artificial wind devices
The artificial wind here be meant adopt that artificial means force directly that gas flow produces with the similar moving air of natural wind.Artificial means are meant the power-equipment and the method that can make gas flow.The equipment that produces artificial wind is not limited to top ventilating fan.This artificial wind can also be that the draught head abnormity becomes artificial wind regimes such as artificial wind-tunnel.Gas is meant air and other artificial gas.
Blow wheel rotation with blower fan as wind regime and drive generator for electricity generation, the three-phase alternating current that sends is by the silicon bridge rectification, and after special controller is handled, be stored in the storage battery with the PWM way of output, the back is inserted inverter and is sent in the partial electric grid with sinusoidal wave 220V voltage.
Special controller can insert more than one ten simultaneously with many interior parallel generator groups.
Directly send out the three-phase alternating current of 220Vor380V, multimachine is incorporated into the power networks in the Phase synchronization device, promptly can be connected to the grid after sending into synchronous booster.
The basic principle of the technology of the present invention is: utilize artificial wind to be the power wind regime, promote the impeller rotation, therefore the generator that is connected with impeller shaft is driven and sends electricity, and the alternating current that sends is treated and obtain utilization.For in the space that solves relative closure as the problem of the air flow property of basement, subway station, industrial premises, stadiums; usually can resort to coercive measures makes the air of interior air of enclosure space and outside produce convection current, or forces the air flows of local space.After the flowing velocity of air reaches certain value, its value just displays, that is to say the value that has possessed energy recuperation,, be used so adopt wind generating technology that the energy in the moving air is transformed into electric energy because of energy is present in the flow air.The density of air only is 1, only be 1/718th of water, so low energy density must adopt specially designed air guide structure, not only can improve the density of wind energy but also can improve the quality of wind, has consequently guaranteed giving full play to of wind generating technology.
Under the prerequisite of the quality of the wind energy concentration of fully having excavated artificial wind and wind, the improvement by to the wind generating technology that is applied to natural wind has greatly improved the rate of recovery to artificial wind energy.
The running orbit and the wind energy of the wind of the artificial wind devices output of foundation distribute, and blade is optimized design; Actual wind speed condition and situation of change according to blower fan improve electric generator structure.Solve wind power system thus and cooperate, reclaim blower fan fully and release the energy that is added in the moving air (artificial wind) with the effective of blower fan.
The electricity that wind-driven generator sent in addition cushions in storage battery and is promptly arrived industrial voltage by inversion after handling through controller, is directly used in the productive life.For adapting to such application mode, the power control technology that control system is taked multimachine and connect, output inserts the storage battery of suitable capacity, and the electrode of storage battery connects inverter simultaneously, from the direct access to LAN of specified alternating current or power consumption equipment of inverter output.
For implementing the technology of the present invention, selected the combination of industrial fan and wind power system.What at present industrial fan was used is very extensive, is many with 138 specifications, has obtained the distribution of wind speed after tested, and as according to Blade Design being the tadpole shape, the relatively stable wind-driven generator that determined of wind speed is a low-speed generator.The head that is made of impeller and generator is fixed on the geometric center of blower fan.The input port of the power line access control system of drawing from generator.
Whole artificial wind wind power system is made of following part: switch on after the industrial fan that wind gathering is handled is started working, the wind (artificial wind) that produces directly blows head, being turned moving with the vertical impeller of wind direction and driven the generator for electricity generation that axle connects on the head, the three-phase alternating current that sends send into multimachine by the power line that is connected generator output end and controller input and the electric control system that connects in, the electric current of handling that is transformed into DC by AC by output port through power line and the storage battery buffering back that connects insert the inverter inversion by the inverter input port, and scratch the rated power that obtains and the alternating current of voltage is sent into the use of partial electric grid electricity supply and use equipment.
The power consumption of former blower fan can be more than 1KW, and existing product has all emitted this energy, and behind the adding wind generator system, the power consumption rate of recovery through calculating native system reaches more than 30%.
