FIELD: electricity.
SUBSTANCE: invention relates to the wind power engineering. Wind-driven generator control system consists of wind wheel 1 connected by shaft 2 with rotor of electric generator 3 connected to rectifier 4 and rotor rpm measuring device 5 to which double-threshold comparator 6 is connected. Signal from rectifier 4 is fed to power inputs of controlled converters 7, 8 and 9, which perform PWM control of output current and voltage in accordance with signals coming from analogue outputs of control device 15 to inputs of converters 7, 8 and 9. Converter 7 is connected via inverter 11 to load 12. Converter 8 is designed to control charging of accumulator 13 and through switch 10 is connected to input of inverter 11 by signal from device 15. Converter 9 serves to control the ballast load current 14. Voltage sensors 16, 18, 22, current sensors 17, 19, 23 measure values of output voltages and currents according to rectifier 4, converters 7 and 9. Voltage sensor 20 and current sensor 21 measure voltage and charging/discharging current of accumulator 13.
EFFECT: invention is aimed at improvement of energy efficiency of wind-driven power plant.
