Magnetic spectrum energy storage power supply

What is a magnetically suspended flywheel energy storage system (MS-fess)?

The magnetically suspended flywheel energy storage system (MS-FESS) is an energy storage equipment that accomplishes the bidirectional transfer between electric energy and kinetic energy, and it is widely used as the power conversion unit in the uninterrupted power supply (UPS) system.

Can magnetically suspended fess be used for energy storage?

In addition, the tunable magnetic forces could actively suppress the vibration amplitudes of the stator part and FW rotor suffering the disturbance at a high rotational speed 18, 19. Thus, the magnetically suspended FESS (MS-FESS) is promising for energy storage, considering the extremely low vibration and the active controllability.

Can MS-fess be used as energy storage device in UPS system?

The experimental results of the speed regulation. The MS-FESS could be used as the energy storage device in the UPS system to realize the charging and discharging, such that the high-efficiency conversion between the kinetic energy and the electric energy could be accomplished.

What are the parts of a magnetic suspension system?

The mechanical body includes the stator house, the flywheel rotor, and the rotor shaft. The stator parts of the magnetic suspension system and motor are mounted on the stator house, and the housing is also used to provide a vacuum environment to the motor.

How does a magnetic suspension system work?

The stator parts of the magnetic suspension system and motor are mounted on the stator house, and the housing is also used to provide a vacuum environment to the motor. The flywheel rotor uses carbon fiber material that is fixed on the rotor shaft, and the rotating velocity is controlled by a permanent magnet synchronous motor (PMSM).

How does fess-ups stabilize DC-bus voltage?

Thus, the DC-bus voltage of the load side is stabilized by the FESS-UPS system at the discharge state. First, the simulation results of the DC-bus voltage are tested at the discharging and charging modes, and the voltage curves are plotted in Fig. 7.
