摘要
本文建立了电机的扭振方程和电路方程相耦联的统一数学系统,得到了它的解.研究了电源电压、扭转刚度等参数对启动过程的扭振、电磁力矩、电流等的影响,得到了一些有工程实际价值的规律和消除这种大扭振的途径,理论结果和实验结果吻合很好.
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.
