Abstract: This article proposed a compact and highly efficient flywheel energy storage system. Single coreless stator and double rotor structures are used to eliminate the idling loss caused by the flux of permanent magnetic machines. A novel compact magnetic bearing is proposed to eliminate the friction loss during high-speed operation.
A flywheel energy storage system (FESS) uses a high speed spinning mass (rotor) to store kinetic energy. The energy is input or output by a dual-direction motor/generator. To maintain it in a high efficiency, the flywheel works within a vacuum chamber.
Moreover, the force modeling of the magnetic levitation system, including the axial thrust-force permanent magnet bearing (PMB) and the active magnetic bearing (AMB), is conducted, and results indicate that the magnetic forces could stably levitate the flywheel (FW) rotor.
The rotational speed of the flywheel (FW) rotor is accelerated to the rated value at the charging state of the FESS, and the electrical energy on the grid is transferred to mechanical energy [, , ].
An FW rotor for storing energy (500 kJ/kg) was developed to suppress the difference between the electricity supply and demand . The levitation forces, including the electromagnetic force and Lorentz lifting force, could stabilize the FW rotor on five DoFs, but the dynamic displacements of the FW rotor were not presented.
AMB has already been used in industry for some time . Its controllability makes a flywheel rotor possibly works in more flexible working conditions. The aim in the work described in this paper is to develop a prototype of FEES with AMBs. Further research of the new type of FEES can be done based on the prototype.
