WIND POWER PLANT Russian patent published in 2022 - IPC F03D7/04 F03D9/11 

FIELD: wind energy and electrical engineering.

SUBSTANCE: invention relates to the field of wind energy and electrical engineering, in particular to autonomous power supply systems using wind energy. The wind power plant contains a wind turbine, an overrunning clutch connected to a squirrel-cage rotor of an asynchronous generator, the other end of the squirrel-cage rotor is connected to a synchronous machine consisting of a split rotor into outer and inner rings. On the outer and inner rings of the split rotor there is a magnetic circuit and permanent magnets of the fixed stator with windings located in it. The split rotor of the synchronous machine rotates freely relative to the stator of the synchronous machine thanks to a bearing built into the stator of the synchronous machine. A battery of starting capacitors and a load are connected to the stator windings of the asynchronous generator. The stator windings of the asynchronous generator and the stator windings of the synchronous machine are electrically connected to the control system, which is electrically connected to the battery charge controller, storage battery, inverter, switching unit, which is connected to the stator windings of the synchronous machine, the charge controller is connected to the ballast load.

EFFECT: stabilization of the output parameters of an asynchronous generator with a squirrel-cage rotor due to the operation of a brushless synchronous machine in motor or generator modes and an increase in the wind flow utilization factor at various wind speeds.
