ELECTRICAL GENERATOR UNIT FOR MICROHYDROELECTRIC POWER PLANT Russian patent published in 2017 - IPC H02K27/28 H02P9/14 H02P9/30 

FIELD: electricity.

SUBSTANCE: electrical generator unit comprises a rotating turbine, an alternating current collector machine, the rotor of which is connected to the rotating turbine shaft, and an automatic flux regulating device that includes triacs for switching the collector machine drive coil taps connected to the control microcontroller. When switching the taps, excitation voltage is applied to a different number of turns of the field winding, from which the magnitude of the generated magnetic flux varies. The device is designed to work in parallel with the AC network, from which the automatic magnetic flux regulating device and the excitation winding 3 of the collector are fed.

EFFECT: increasing the efficiency.
