Summary:A power supply for a superconductive magnetic energy storage system is presented. It permits fast independent regulation of the active and reactive power. The power supply was built with several units connected in parallel. Each unit consists of a 24-pulse bridge converter, thyristor-switched tap-changing transformer, and thyristor-switched capacitor bank. System operation was analyzed by computer simulation, and a feasible system realization is shown. A superconductive magnetic energy storage system with the proposed power supply has the capability of leveling the load variation, damping the low-frequency oscillation, and improving the transient stability in the power system. This power supply can be built with commercially available components using well-proven technologies.< >
