ASYNCHRONOUS AC SYNCHRONOUS AXIAL-RADIAL WIND TURBINE GENERATOR Russian patent published in 2023 - IPC H02K47/00 F03D9/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to wind power converters, can may be used for converting incoming air stream kinetic energy (for example, energy of incoming air stream when using on mobile local objects, wind energy when using on stationary local objects) into alternating current electrical energy. The technical result is achieved due to the fact that asynchronous synchronous axial-radial alternating current wind turbine generator contains a fixed platform, rigidly installed on a boom-holder, front and rear bearing units, the inner stator with a fixed axis pressed into the hole made in the center of the fixed platform, and the outer rotor containing a hub with blades installed on the hub outer surface with a fairing at the front side. The wind generator is designed as a two-cascade generator and consists of an exciter and the main generator, the magnetic system elements of which are fixed to the inner stator and the outer rotor. The exciter consists of an axial exciter field winding, in slots of which a three-phase exciter field winding and an axial exciter armature winding are installed. The wind generator also contains an inverter, the input of which input is connected to the main generator three-phase armature winding phase commencement, the inverter output is connected to the exciter three-phase excitation winding phase commencement.

EFFECT: invention provides possibility to improve operational and technical characteristics of wind turbine, in particular, to improve the quality of generated electricity alternating current by minimizing the generator output voltage deviation from the set frequency and amplitude when changing the velocity of incoming air flow, increase reliability of wind turbine by reducing probability of overheating the exciter windings and the main generator by facilitating the wind turbine elements thermal operation mode.
