The final size using electrical power has closer relation with storage battery size.The size of power more depends primarily on the big of air quantity
It is small, and it is not only the size of head power.Interiorly, small wind-power electricity generation chance is more suitable than big.Because it is easier quilt
Small air quantity drives and generated electricity, and continual small wind can more supply larger energy than a period of time blast.People are also when calm
The electric energy that normally can be brought using wind-force.
Current small-sized wind power generator, impeller is fixed, so can be right when wind speed is larger, wind-force change frequency is higher
Integrated model can be damaged long for a long time by great impact power, and blade must have initial inclination angle, and circumferential component is just had like that to be made
Rotor driven rotate.Can be efficiently against disadvantages mentioned above, the blade phase of generating set using feather power conditioning technology
There are different generator rotor angles for wind direction, when wind speed persistently changes, the generator rotor angle of blade remains at best angle, so that wind-force
Generating set is possible to remain the optimal conversion efficiency of its wind wheel under different wind speed, makes power output maximum.
In summary, inventing a kind of small-sized wind power generator pitch control mechanism simple in construction, being easily installed has weight
The realistic meaning wanted.
