Title:
FLYWHEEL ENERGY STORAGE AND INERTIA CONDUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/005951
Kind Code:
A1
Abstract:
The present disclosure provides a flywheel energy storage and inertia conduction system, comprising a motor, a flywheel energy storage unit, an inertia conduction device, and a generator. The flywheel energy storage unit comprises a flywheel rotor, a flywheel controller, and an auxiliary device. The inertia conduction device is used for conducting rotational inertia and transferring flywheel energy, the flywheel rotor is disconnectably and transmissionally connected to the inertia conduction device, the inertia conduction device can accept changing rotational speed inputs, then the rotational speed can maintain a constant output by means of the speed change, the inertia conduction device is disconnectably and transmissionally connected to the generator, and the generator is used for generating and outputting stable electric energy driven by the inertia conduction device. Connecting the flywheel energy storage and inertia conduction system provided in the present disclosure to a power grid can effectively alleviate the risk that low rotational inertia of a high power electronic system caused by a high proportion of new energy in power grids at present and in the future causes the stability and the regulation capability of the power grid to be drastically reduced.
