Superconducting magnetic energy storage
A Superconducting Magnetic Energy Storage (SMES) system stores energy in a superconducting coil in the form of a magnetic field. The magnetic field is created with the flow of a direct current (DC) through the coil. To maintain the system charged, the coil must be cooled adequately (to a “cryogenic” temperature) so as to manifest its superconducting properties – no resistance to the flow of cur...
متن کاملSuperconducting Magnetic Energy Storage: Status and Perspective
The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high. This makes SMES particularly interesting for high-power and short-time applications (pulse power sources). A SMES releases its ene...
متن کاملFlywheel Energy Storage System with Homopolar Electrodynamic Magnetic Bearing*
.Abstract – The goal of this research was to evaluate the potential of homopolar electrodynamic magnetic bearings for flywheel energy storage systems (FESSs). The primary target was a FESS for Low Earth Orbit (LEO) satellites, however, the design can also be easily adapted for Earth-based applications. The main advantages of Homopolar Electrodynamic Bearings compared to more conventional Active...
متن کاملSuperconducting Magnet Energy Storage Unit
Uninterruptible power supplies (UPS) have been used to sustain a continuous power supply to certain critical loads protecting them against unexpected power outages as well as over and under voltage conditions. It requires fast response, compensation and instant availability of electrical power. One of important components that considerably affect these characteristics is energy storage units li...
متن کاملCharacteristics of superconducting magnetic bearings for 50kWh-class flywheel system
We are developing a 50 kWh-class flywheel energy storage system as a national project, using a new axial superconducting magnetic bearing (Ax_SMB) technology. The project has started in FY2005 and will continue to FY2007. The Ax_SMB is composed of Fe core and superconducting coil, which are simply torus-shape. It generates strong restoring force in axial direction. It can realize non-contact le...
