| Abstract: | An unified mathematical system which couples torsional vibration equation and circuit equation of a synchronous machine is proposed in this paper. The effects of the parameters as the power line voltage and torsional stiffness and other on such factors as torsional vibration, electromagnetic torque and current in the starting process are investigated. Some useful rules in engineering and the way to eliminate the large torsional vibration are achieved. The theoretical results correspond with the experimental results very well. |
