Abstract
A superconducting magnetic energy storage system (SMES). The SMES includes a toroidally wound super conducting magnet having a toroidal magnetic core with a charging winding and a discharging winding. The charging winding and discharging winding are wound on the toroidal magnetic core. The SMES also includes a DC power source, the DC power source operable to provide DC current to the charging winding of the toroidally wound superconducting magnet, and a modulator operably connected to the DC power source and the charging winding, the modulator operable to modulate at least a portion of the DC current applied to the charging winding of the superconducting magnet. The energy is stored in a magnetic field of the superconducting magnet by applying a current to the charging winding of the superconducting magnet, and energy is withdrawn from the magnetic field by a current flowing in the discharging winding.
