Embodiment Construction

[0045] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0046] See figure 1 , Wind power management and energy storage devices based on flywheel energy storage include: DSP controllers for power management and control, flywheel systems for energy storage and power management actuators, and IGBT modules for power conversion of the flywheel system. In the resistance box that unloads the excess electric energy, the unloading IGBT that realizes the power switching of the resistance box is used to transform the electric energy of wind power generation and transmit it to the grid-connected inverter of the grid;

[0047] The DC bus of the wind turbine is connected to the inverter, unloading IGBT and IGBT module respectively. Among them, the IGBT module is connected to the flywheel system and the DSP controller, and the DSP controller is connected to the DC bus, inverter, flywheel system and Unload the IGBT.

Abstract

The invention discloses a wind power generation electric energy management and storage device and method based on flywheel energy storage, which belong to the wind power generation field. The wind power generation electric energy management and storage device comprises a DC bus connecting a flywheel energy storage device to a wind power generation system, the output electric energy of a wind driven generator and the grid-connected electric energy of an inverter are detected to adjust the rotational speed of a flywheel energy storage motor, and together with an unloading box, the electric energy management in the wind power generation process is realized, the grid-connected electric energy of the inverter is controlled to be stable, and a grid network or equipment is prevented from impact caused by sudden change of the grid-connected electric energy. As the energy storage device is provided, the use of the unloading box is reduced to the maximum extent, accordingly, and loss of electric energy on the unloading box is reduced, as well as the waste of electric energy. On the basis of serving the electric energy management function in the wind power generation process, compared with a storage battery system, the flywheel energy storage device has long running service life, avoids environmental pollution, and reliably realizes the charge and discharge of high-power electric energy.

Description

Technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generation electric energy management and energy storage device and method based on flywheel energy storage. Background technique [0002] At present, during the operation of the wind power supply system, the grid-connected inverter transmits the electric energy of the wind power to the grid through the DC voltage outer loop control. When the wind energy changes suddenly, the inverter will follow such changes to integrate the electric energy into the grid as much as possible. Due to the strong abrupt nature of wind energy, it causes a sudden change in grid-connected electric energy, which will have an impact on the grid or equipment. When the grid-connected inverter cannot fully follow the change of wind energy or the inverter is fully loaded due to excessive wind energy, the excess energy will be wasted through the unloader. [0003] In the prior art, batteries or fly...
