About How to use the generator wind resistance
In many cases there is gearbox between the blades and the generator to increase the RPM at the driveshaft. In this experiment, you will measure the power output of a wind turbine under load and determine the relationship between optimal resistance and internal resistance. You will use a KidWind MINI turbine and a fan.

In this video I build an axial flux wind turbine with a 12 ft (3.7 m) diameter rotor driving two 12 coil/16 pole axial flux permanent magnet generators that produce up to 3 kW in a ~30 mph wind stream.
The goal of this experiment is to determine the maximum output power of your wind turbine generator. To do so, you must search for the best loading condition by varying the resistance on the circuit. For a wind turbine generator, the best loading condition varies with wind speed (we do not explore this relationship in this lab).
Insulation resistance testing. Testing the insulation resistance of high-voltage power cables and buses, large motor/generator windings, and transformers is extremely important to ensure the integrity of the generator’s winding insulation and the likelihood of developing a ground.

6 FAQs about [How to use the generator wind resistance]
How to optimize a wind turbine generator?
One of key components in the wind turbine is its drive train, which links aerodynamic rotor and electrical output terminals. Optimization of wind turbine generators can not be realized without considering mechanical, structural, hydraulic and magnetic performance of the drive train.
Why do wind turbines produce more power than fixed speed generators?
In theory, some wind turbine generators may be used to compensate the low power factor caused by neighboring consumers. In economic terms, variable speed wind turbine can produce 8-15% more power than fixed speed counterparts .
How can wind turbine generators be improved?
More in-depth analysis should be carried out in the design, control and operation of the wind turbines primarily using numerical, analytical and experimental methods if wind turbine generators are to be further improved.
How do I choose a wind turbine generator?
Generally speaking, wind turbine generators can be selected from commercially available electrical machines with or without minor modifications. If a wind turbine design is required to match a specific site, some key issues should be taken into account. These include: Capital cost and maintenance.
How to control the power output of a type-2 turbine?
Control of power output of a Type-2 turbine can be accomplished by varying the rotor resistance. The objective of a rotor resistance controller in this situation is to seek the operating point at which power extraction from the wind is maximized, and also prevent the power extracted from exceeding the machine’s ratings.
