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 کاملThree-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field
In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...
متن کاملA Novel Control Strategy for Superconducting Magnetic Energy Storage Unit to Improve Power System Stability
In this paper a simple but novel control strategy is developed for Superconducting Magnetic Energy Storage (SMES) unit. The SMES unit is used to improve the dynamic performance of power system. The gain of the controller is determined depending on the power system and the capacity of the SMES unit. A simple delayed function is used to determine the desired power from the SMES unit. Eigenvalue a...
