A Simulator of Superconducting Magnetic Energy Storage and an Experiment of Levelling Load Power Fluctuation

Abstract

A Superconducting Magnetic Energy Storage (SMES) using superconductive coil is effective power storage system. An electric power system using SMES can perform levelling load power fluctuation and improve the, stability of power system. It is impossible to examine a control strategy for levelling load power fluctuation using a SMES, because we can not realize a large capacity of SMES. So we build a SMES simulator as a trial that operates coordinately as a superconductive coil.
In this paper, a superconductive coil composed of a coil and a inverter curcuit is realized by numerical expression and experiment. The contorol strategy based on an auto-tuning of scailing factors with neural network can realize levelling the fluctuating active power and compensating the reactive power using the SMES simulator.
