Superconducting magnetic energy storage (SMES) system would be a valuable system for a power line stabilization. It would increase stability by supporting peak energy and compensating generation shortage. With a development of a large capacity GTO thyristor suitable for 20MW level power conversion system, it is possible to control the four-quadrant of the real power (P) and the reactive power (Q) condition by self-commutated power converters with high performances. In this paper, it is shown a new direct connected multiple current source converters, and also explained the control strategies suitable for a pilot plant of a SMES system. Then they will give the feasibility of the control strategies by showing the EMTP simulation results.
