Large-scale wind turbines do not generate electricity until the wind speed is reduced (about 3.5 m/s). They adjust the pulp before the nominal wind speed to follow the maximum power;
Small wind. the turbines have an energy collection device. Increasing wind speed to improve power generation efficiency results in expansion (the effect is better) and shrinkage (the effect is not obvious), but it is rarely used now
1: Increase the blades of the windmill so that the windmill has enough power. The power drives the generator. The bigger the blades, the better.
2: The power of the windmill has increased, but the speed is not enough. You can give the generator a 2x gear to drive the generator. That is, one rotation of the windmill will drive the generator. generator to turn twice (professional The same principle is applied(applicable to wind turbines) The prior wind force must be sufficient. Coastal areas are most suitable for wind energy production. Do not change the number of revolutions inside the generator. Your generator should be able to generate a voltage of 14 to 18 V and the power should be 200 W. The simpler the better. The more complicated it is, the more energy it will consume.
