Title:
FLYWHEEL ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/005950
Kind Code:
A1
Abstract:
A flywheel energy storage system (1), comprising: an electric motor (112); a flywheel rotor (111), the electric motor being connected to the flywheel rotor to drive the flywheel rotor to rotate; and an asynchronous generator (20), the asynchronous generator comprising a stator and a rotor, wherein a flywheel rotor is disconnectably transmittingly connected to the rotor to drive the rotor to rotate, and the stator can be connected to a power grid and input electrical energy having a stable frequency into the power grid. The flywheel energy storage system is connected to the power grid without needing to use a power electronic device, so that necessary voltage and frequency support can be provided for the power grid, and the risk of large frequency deviation of the power grid is reduced.
