Abstract :
The features of instability in a long-distance bulk power transmission model system with superconductive power transmission lines or with superconductive synchronous generators are analyzed numerically. It is shown that self-excited oscillation is easily induced in superconductive AC power transmission systems. Torsional oscillation and electromechanical power swing in a model power system with a superconductive turbine generator power plant are analyzed for various system conditions, and it is confirmed in a digital simulation study that adequate energy control of the field winding of a superconductive generator can stabilize the power system
