induction generator

An induction generator is an electric machine that converts mechanical energy into electrical energy by inducing voltage in a fixed armature through the rotation of a rotor. Unlike synchronous generators, induction generators typically require connection to an existing electric supply network to operate, as they do not produce their own magnetic field. When torque is applied to an induction machine, it rotates slightly faster than its synchronous speed, causing induced currents in the rotor. These currents interact with the magnetic field to produce a torque that balances the applied torque, and a stator current flows into the supply network, delivering electrical power. Induction generators are often favored for smaller hydroelectric sites due to their resilience against losing synchronism during power system fluctuations.12
