WIND GENERATOR CONTROL SYSTEM Russian patent published in 2021 - IPC F03D7/04 H02P9/02 

FIELD: wind power industry.

SUBSTANCE: wind generator control system includes a wind wheel that has blades that can rotate relatively to the axis using a pitch control device. The wind wheel is connected by a mechanical shaft with a multiplier, to the output shaft of which the rotor of a synchronous generator is attached. A rectifier and a rotor rotational speed meter are connected to the output of the synchronous generator. The output of the rectifier is connected to a controlled converter, to the output of which the load and the power meter are connected. The system contains an optimum calculator, the first and second functional converters, and a set point adjuster. The outputs of the rotor rotational speed meter and the power meter are connected to the first and second inputs of the optimum calculator, the third input of which is connected to the output of the set point adjuster. The output of the optimum calculator is connected to the input of the first functional converter, the output of which is connected to the inputs of the second functional converter and the pitch control device. The pitch control device changes the angle of rotation of the wind wheel blades relatively to its axis. The second functional converter is connected to the control input of the controlled converter; it changes its conversion coefficient.

EFFECT: increased energy efficiency of the wind generator.
