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.
Boeing has developed a 5 kW h/3 kW small superconducting maglev flywheel energy storage test device. SMB is used to suspend the 600 kg rotor of the 5 kWh/250 kW FESS, but its stability is insufficient in the experiment, and damping needs to be increased .
The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.
In order to complete accurate control of the magnetic levitation system, the data acquisition (DAQ) board can collect the displacement variations of the FW rotor on five DoFs, and then the main control system developed on a DSP chip and an FPGA chip can finish the signal processing and code programming.
Moreover, the magnetic levitation system, including an axial thrust-force PMB, an axial AMB, and two radial AMB units, could levitate the FW rotor to avoid friction, so the maintenance loss and the vibration displacement of the FW rotor are both mitigated.
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
