Improvement of generator damping through superconducting magnetic energy storage (SMES) in dynamic simulation test of power system

A prototype, double-DSPs controlled power conditioning system (PCs) for superconducting magnetic energy storage (SMES), is used for experimental study in dynamic simulation test of a power system. The function of the SMES is to improve the dynamic performance of a single-machine infinite bus for power system. The experimental results show that the transfer of SMES energy 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 little hardware.
