METHOD OF ENERGY SUPPLY OF COMPONENTS OF WIND-DRIVEN POWER PLANT, AS WELL AS POWER SUPPLY DEVICE AND WIND-DRIVEN POWER PLANT WITH SUCH DEVICE Russian patent published in 2021 - IPC H02J11/00 F03D9/00 

FIELD: physics.

SUBSTANCE: use: in electric power engineering. According to the method, energy in the operating mode of the wind-driven power plant is selected by the power supply device (22) from energy generated by generator (10) of the wind-driven power plant (100), and component (56–72) of the wind-driven power plant (100) for power supply is provided, wherein voltage generated by generator (10) of energy is rectified by rectifier (12) and intermediate accumulated in intermediate circuit (14) of constant voltage, wherein energy for supply of component (56–72) is selected by power supply device (22) from intermediate circuit (14) of constant voltage, wherein using transformer (34) of power supply device (22) voltage obtained from intermediate circuit (14) of constant voltage, is converted into voltage matched with component (56–72), in particular 400 V, wherein transformer (34), in particular, on its primary side receives energy from intermediate circuit (14) of constant voltage and, in particular, on secondary side, at output (36) provides energy for components (56–72), and transformer (34), in particular, on its secondary side is additionally configured to be connected to power supply network (20) to provide power from power supply network (20) for power supply of components (56–72) or drive circuit (39).

EFFECT: technical result is provision of power supply of at least one component of wind-driven power plant.
