The superconducting magnetic energy storage (SMES) system would be a valuable system for power line stabilization. It would increase stability by supporting peak energy and compensating generation shortage. With the development of a large‐capacity GTO thyristor suitable for 20‐MW‐level power conversion systems, it is possible to control the four‐quadrant real power ( P ) and the reactive power ( Q ) condition by self‐commutated power converters with high performance. This paper describes a new direct‐connected multiple current‐source converter, and also explains suitable control strategies for the pilot plant of an SMES system. The feasibility of the control strategies is demonstrated by EMTP simulation results. © 2000 Scripta Technica, Electr Eng Jpn, 133(1): 87–96, 2000
