AUTONOMOUS POWER SUPPLY SYSTEM Russian patent published in 2023 - IPC F03D9/25 F03D7/04 H02P9/00 H02K21/12 

FIELD: electrical engineering.

SUBSTANCE: autonomous power supply system contains a wind wheel, a storage battery, and an inverter. It also contains a freewheel, a synchronous generator with a stator, which is made of inner and outer rings. The system also contains a switching unit, which is controlled by a signal from the microcontroller. The microcontroller receives information about the wind speed from the anemometer, about the state of charge of the battery from the charger, about the consumer load from the current and voltage sensor, about the magnitude of the generated current and voltage from the current and voltage sensor, which allows, depending on the wind speed and power of electricity consumers switch the stator windings according to the delta-star connection, stabilizing the voltage on the phases of the synchronous generator in a certain range. The generated energy through the charger charges the batteries. Energy from the battery through the inverter provides power to consumers.

EFFECT: increasing the reliability, energy efficiency and stabilization of the output parameters of the synchronous generator, as well as simplifying the design of the autonomous power supply system.
