Design and test of controller in Power Conditioning System for Superconducting Magnetic Energy Storage

A prototype, double-DSPs controlled power conditioning system (PCS) for super-conducting magnetic energy storage (SMES), is used for experimental research in dynamic simulation test of power system. The function of SMES is to improve the dynamic performance of a single-machine infinite bus for power system. The experimental results show that the energy transfer of SMES is done almost immediately depending on the system requirement, and SMES is able to restore system stability for short circuit. The control algorithms for the SMES are simple and implementation has required very a little hardware.
