WIND GENERATOR Russian patent published in 2018 - IPC F03D7/00 H02P9/00 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind generator contains a wind wheel, connected by a mechanical shaft with a rotor of an electric machine, which is connected to the battery and the input of the inverter through the normally-closed first switch and the rectifier-charger, which is connected to the load, the timer. Device is additionally equipped with a two-threshold comparator and a normally-open second switch, the two-threshold comparator is connected to an input to the electrical machine, and the output is connected to the control input of the normally-closed first key and to the timer input, the output of the normally-open second key connected to the control input, with which the battery is connected via a voltage converter to an electrical machine, while the electric machine is reversible and operates both in the generator mode and in the engine mode.

EFFECT: invention is aimed at reducing the lower threshold of the operating range.
