What is an induction generator?

The induction generator, also called an asynchronous generator, is the type of alternating power generator. The generator rotor is placed in a rotating magnetic field, and the rotor is then blasted by an external mechanical energy source, turning faster than the magnetic field. The rotating shaft begins to pull the magnetic field field forward and sends electricity flowing into the generator coils. Induction generators are less complex and robust than other forms of generators and can continue to effectively produce force if their rotor speed changes. The induction generator needs an external electricity supply to create its rotating magnetic field and start working, but as soon as he started to generate performance, he can continue running in itself if he has a mechanical energy source. Generatory power at different speeds allows the turbine to remain in different wind conditions. Small sources of hydroelectric energy, sometimes called micro hydro generators, also use induction generateory. These generators are equipped with a device called an induction generator controller that prevents damage to the induction generator and allows it to function during changes in water flow. Due to the simplicity of their design, very small induction generators can be able to power home appliances with easily accessible parts such as washing machine engines.

wind turbines often use a design called a double -fed induction generator in which the rotor windings are connected to an electronic converter that can import or export reactive power to a generator or generator as needed. This allows the generator to remain synchronized with the Power Grid during wind speed changes. It also causes the energy system as quite stable allows wind turbines to continue running and providing the grid power continuously in the case of a grid voltage, which is a capacity called lowApěťová ride.

Induction generators differ from synchronous generators in which the rotor and magnetic field rotates at the same speed. Synchronous generators can produce electricity more efficiently than induction generators, but they need to be driven at constant speed. The basic principles of the induction generator can be applied in the opposite direction to create an induction engine in which the rotor is made to rotate more slowly than the magnetic field to convert electricity into mechanical energy.
