VoltageSagsCompensationUsingaSuperconducting
Flywheel Energy Storage System

Abstract—Thispaperpresentsavoltagesagcompensator,which
uses a flywheel energy storage system with superconducting mag-
netic axial thrust bearing (SMB) and a permanent magnet radial
bearing (PMB). The SMB was built with Nd-Fe-B magnet and
YBCOsuperconducting blocks,refrigerated withliquidNitrogen.
The magnets are assembled with magnetic flux shapers in order
to increase the levitation force and the stiffness. The radial PMB
is used to positioning the vertically arranged switched reluctance
machine (SRM) used as motor/generator. Simulations of the
power electronics and SRM show that the system can work up to
30,000 rpmsupplying the required energy during disturbances.
Index Terms—Flywheels, high-temperature superconductors,
