The present invention solves above-mentioned technical matters by following technical proposals:
The invention provides a kind of wind energy turbine set anemometer tower virtual method, its feature is, it comprises the following steps:
S
1, a temperature sensor, an air velocity transducer and a wind transducer be installed in axial fan hub center;
S
2, utilize this temperature sensor, this air velocity transducer and this wind transducer to measure respectively temperature, wind speed and the wind direction of axial fan hub center;
S
3, wind speed by axial fan hub center and aerovane calculate wind speed and the wind direction at blower fan 10m, 30m, 50m and 70m place;
S
4, measure air pressure and humidity below blower fan 10m.
Preferably, step S
4middle respectively by a baroceptor and humidity sensor measurement air pressure and a humidity.
Positive progressive effect of the present invention is: the present invention can measure temperature, wind speed and wind direction by sensor being set in axial fan hub center, and can calculate by the data-speculative recording corresponding wind speed and the wind direction of other height of blower fan, thereby can in obtaining wind energy information, save cost, also save the cost of wind power generation.
Accompanying drawing explanation

Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, wind energy turbine set anemometer tower virtual method of the present invention comprises the following steps:
And in specific implementation process, in step 103, can pass through respectively a baroceptor and humidity sensor measurement air pressure and a humidity.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection scope of the present invention.
