Power charge/discharge control system and method for wind turbines using flywheel energy storage

摘要

Various embodiments of the present invention relate to a system and method for controlling the charge / discharge of a wind turbine using a flywheel energy storage device, wherein a power charge / discharge control system of a wind turbine according to an embodiment of the present invention generates electric energy from wind energy Double induction type wind turbine; A charge / discharge controller for comparing the real-time production electric power of the electric energy produced from the double excitation induction type wind turbine generator with a preset reference power to generate and output at least one PWM signal according to the comparison resu A bidirectional converter that receives the PWM signal and in response supplies the real-time production power to the flywheel energy storage device or supplies the real-time production power to the dual-excitation inductive wind power generator according to a comparison result between the real-time production power and the reference power; A flywheel energy storage device for charging the real-time production electric power supplied from the bidirectional converter or discharging the pre-charged electric power; And a power output device for outputting the real-time production power to the outside. With such a configuration, the system and method for controlling the charge / discharge of the wind turbine using the flywheel energy storage device of the present invention is capable of stably carrying out the production of electric power by the wind turbine even when the wind speed is not constant.
