At present, small-sized wind power generator is mainly used in the backcountry away from electrical network, as areas such as pastoral area, grassland, mountain area, islands.It is very difficult to erect power transmission lines in these areas, and electric cost is also very high; Simultaneously, often there is bigger wind resource in these areas, are particularly suitable for the use of small-sized residents aerogenerator.In recent years, the development of the following wind generator system of China 10kW was very fast, and especially the following type of 2kW has all been obtained many successful experience from manufacturing and designing to operation maintenance, had solved large quantities of farmings of not having a few electricity of electricity, herded, fisherman's basic household electricity problem.But existing system generally adopts generator output directly accumulator to be charged, and the wind energy conversion system conversion links is not controlled, and makes power coefficient lower, generally about 0.3.According to the Bates theory, the ultimate value of power coefficient is 0.593, if the control wind energy conversion system always moves with best tip speed ratio, annual electricity generating capacity can improve 20%~30%.Only move under best tip speed ratio according to wind energy conversion system, the theory of ability Maximum Power Output is an object with the small-sized wind power generator, is the problem that one of ordinary skill in the art pay close attention to and need to solve to its analysis and research of carrying out maximal power tracing.And small-sized wind power generator performance test platform is not arranged at present as yet, and research and analyse its output power, and it is optimized, restrict small-sized wind power generator thus and realized the purpose that power optimized is controlled.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of simple in structure, convenient test and result small-sized wind power generator Performance Test System accurately.
The purpose of this utility model is achieved in that the small-sized wind power generator Performance Test System, its characteristics are to comprise small-sized wind power generator, air channel, wind regime and industrial computer, small-sized wind power generator is towards the air channel and be located at air outlet, and air outlet place in air channel is equipped with wind gage; Wind regime is the other end that axial flow fan is located at the air channel, and links to each other with ventilation blower with frequency converter, is used to regulate its rotating speed to produce the simulation wind speed; Wind gage and aerogenerator are by data acquisition card connection industrial computer.
As further optimization of the present utility model, described wind regime is that many axial flow fans that are set up in parallel constitute, and can help the nature wind speed simulation more like this.
Further improve as the utility model, the base of described small-sized wind power generator is fixed on the sleeve moving up and down, and the upper-lower position of scalable small-sized wind power generator to be detected makes it be beneficial to detection like this.
Further optimize as the utility model, rectification sieve also is installed in the described air channel, what can produce the ventilation unit as wind regime distinguished and admirablely carries out rectification, makes it go out to keep stable at air outlet, helps test.
The utility model is simple in structure, reasonable in design, has convenient test and characteristic of accurate as a result.
The utility model is by setting up open wind tunnel test experiment porch, the small-sized wind power system performance evaluation that certain type 1kw mag-dynamo constitutes is found, if can make the output current of generator follow output voltage changes according to certain rule, wind energy conversion system is moved with best tip speed ratio, from its maximum power point of motion tracking, thereby has higher reference value to improving whole wind electric system energy conversion efficiency.

Embodiment
As shown in Figure 1, a kind of small-sized wind power generator Performance Test System, mainly comprise small-sized wind power generator 1, air channel 2, wind regime 3 and industrial computer 6, small-sized wind power generator 1 base is fixedly mounted on the sleeve 4, small-size wind power-generating 1 is moved up and down, position to aerogenerator 1 is regulated, and to guarantee the stable of test mode, avoids because of the systematic measurement error that reason causes is installed; For the polymerization wind energy, design and produce air channel 2 as gas channel, rectification sieve 9 also is installed in air channel 2, and wind gage 5 is installed at 2 air outlet places in the air channel, so that wind speed is measured; Wind regime 3 is made up of nine axial flow fans, and regulates the ventilation blower rotating speed to produce the simulation wind speed with frequency converter 7.In the generator test system, air speed value to be measured and aerogenerator output voltage and electric current are sent in the industrial computer 6 by data collecting card 8, carry out Signal Processing and analysis.Have easy, the effective characteristics of test.
The utility model based on the little fan test technology of open wind-tunnel by axial fan as driving source, adopt wind-force to realize the mode that flexibly connects, mainly be in order to improve speed governing stability, and do further research according to this.
Referring to Fig. 2, test philosophy of the present utility model all is made up of at the pulsation wind speed that fierceness changes mean wind speed and each moment by: natural wind.Randomness feature according to wind speed changes when the performance of test minitype permanent magnetism aerogenerator, provides wind regime with blower fan, and regulates rotation speed of fan to produce the simulation wind speed with frequency converter.Aerogenerator output voltage and the data collecting card of electric current by being connected with electric cabinet are sent in the industrial computer, carry out Signal Processing and analysis.
In the performance test analysis process, the wind speed that wind gage 5 measures must be converted into the wind speed size on aerogenerator 1 wind wheel like this, suppose now according to shellfish so, wind gage 5 places are identical with the flow at generator 1 wind wheel place, promptly
M=ρA
1v
1=ρA
2v
