Abstract

This paper proposes a new combined power-conditioning system for large-scale superconducting magnetic energy storage; it consists of a DC chopper and a PWM (pulse-width modulation) voltage-source converter. The proposed system can independently control the active and reactive power of the utility network by regulating the chopper duty cycle and the converter firing angle. The operational concept was verified through mathematical analyses using an equivalent circuit. The dynamic interaction was analyzed using a simulation model with EMTP (Electromagnetic Transients Program). The analysis results show that the new system is feasible for development with commercially available components and technologies.
