Abstract

A superconducting magnet energy storage (SMES) system for power-transmission-line stabilization is studied using an experimental model system. It has a DC intertie section using convertors in an AC transmission line, with SMES used in series in the DC section. The distinctive characteristics of this system are that independent stabilization can be made for each AC line and that the power flow through the DC section can be controlled. The model system has pulsewidth-modulated GTO (gate-turn-off) converters, a superconducting pulse magnet, and a simulated power line system with generators. Measured characteristics of the system are discussed. Results of some simple line-fault experiments are shown.<>
