Abstract
This paper describes how the power system ability can be improved by introducing a superconducting generator (SCG) into power system networks. This is of particular interest in the case of power system network with IPP (independent power producer). In this work, a digital type SCG model for an existing analog real-time power system simulator was developed, and experimental studies by use of the above-mentioned equipments have been conducted to investigate the effects of SCG on available generator power output and power transmission capacity. The influence of generator constants on SCG's behavior is studied in a signal machine infinite bus power system model. A comparison of available generator power output and ATC (available transmission capacity) is made between SCGs and conventional generator (CG) in a five-machine infinite bus power system model. The experimental results have shown the advantages of SCG over CG in terms of power system stabilities.
