SIMULATION FOR ELECTRICAL CHARACTERISTICS OF A SUPERCONDUCTING GENERATOR CONNECTED TO A POWER-SYSTEM

This paper describes simulation studies on the electrical characteristics of a superconducting generator (SCG) connected to a power system. In the system for the simulation studies, the SCG is connected to an infinite bus through two transmission lines in parallel. The equation describing the SCG is the so-called Park's Equation, which is derived from electromagnetic analysis. The characteristic of the driver of an SCG is taken into account, which affects the transient behaviors of the SCG. The initial values when the system changes (e. g. the system fault) are considered. The simulation results agree well with the experimental results. The torque and the Joule heating of the cold and warm dampers during transient states are calculated.
