Adaptable power supply for superconductive magnetic energy storage system

Abstract

A new power supply which permits the independent regulation of the active and reactive power of a superconductive magnetic energy storage (SMES) system is discussed. The power supply consists of 20 units connected in parallel. Each unit contains a 24-pulse bridge converter, a thyristor switched capacitor bank. An SMES system using the power supply is capable of improving power system stability and oscillation damping, as well as performing load leveling. The power supply can be built with commercially available components using well-proven technology.<>
