The invention discloses a hundred-megawatt level heavy type
flywheel energy storage system based on gas magnetic fluid float cylinder suspension. The hundred-megawatt level heavy type
flywheel energy storage system based on the gas magnetic fluid float cylinder suspension comprises a heavy type
flywheel, a rotating shaft, a driving unit and an output unit. A float cylinder is arranged on the rotating shaft, and the float cylinder is one separation or combination of an
air cushion float cylinder, a magnetic suspension float cylinder and a fluid float cylinder. The float cylinder is added on the rotating shaft,
load bearing capability of the rotating shaft is improved, and the problem that a heavy type flywheel can not be adopted by an existing
flywheel energy storage system is solved. The hundred-megawatt level heavy type
flywheel energy storage system has the advantages of being high in
energy storage efficiency, strong in dilatation capability and wide in energy storage scale, and has the advantages of being high in
power density, long in service life, limitless in charge-
discharge times, free-of-
pollution and the like as traditional
flywheel energy storage technology. The hundred-megawatt level heavy type
flywheel energy storage system simultaneously is low in construction requirement, is mainly used in flat suppression fluctuation and smooth grid-tied, can be used for constructing of a super-large scale energy storage
pitch peak
power station, and can also be used as a distribution type intelligent
microgrid energy storage core.
