CONTROL METHOD OF GENERATOR OF POWER ELECTRICAL INSTALLATION (VERSIONS) AND POWER ELECTRIC PLANT Russian patent published in 2020 - IPC H02P9/04 F03D9/25 

FIELD: power engineering.

SUBSTANCE: invention relates to control method of electric power plant generator. Generator comprises stator of generator connected by means of magnetic field with generator rotor. Method includes operation of the generator stator at the first voltage level. Next step involves monitoring by means of one or more sensors of at least one of the following: rotation speed of the rotor or voltage on the rotor of the generator. Then, the low voltage source is electrically connected to the generator stator to reduce the first voltage level on the generator stator by a predetermined fraction, when the rotor rpm is within the lower speed range or the rotor voltage exceeds a predetermined threshold to increase the rotor rpm operating range. Lower speed range includes a range less than 1000 rpm (rounds per minute). Increase of working range of rotor speed increases output of electric power with electric power plant in lower speed range.

EFFECT: technical result is higher efficiency at low speeds.
