Abstract

An improved power system with many potential good properties may be obtained with introduction of Superconducting Generator (SCG), which has a superconducting field winding that leads to many advantages such as small size, high generation efficiency, low impedance, and so on. Many researches have confirmed the improving-effect of SCG on power system stability. In this work, the influence of SCG on power transfer capability is studied by way of conducting real-time simulation using a digital type SCG model and an existing analog type power system simulator. In the real-time simulation with a 5-machine infinite bus power system model, ATC (Available Transfer Capability) from generator site to load site are examined and, comparison is done between the ATCs in cases of SCG and the conventional generator (CG). The real-time simulation results have verified the effect that SCG can improve the ATC of power system and illustrated the advantage of SCG over CG from the point view of ATC enhancement.
