摘要
利用同步电动机的状态方程,研究了同步电动机在突加负载时的动态过程。经过多次迭代,分别得到了动态稳定极限和“首次摆动”瞬态稳定极限,并与由瞬态功角特性和等面积法则得到的瞬态稳定极限进行了比较。另外,还研究了机组转动惯量对动态稳定极限和突加负载时动态过程的影响,最后得出了一些有用的结论。
The dynamic performance of synchronous motor under abrupt change of load is investigated using the state equation. Through many iterations, the dynamic and ' First swing' transient stability limit are found, the late is compared with the results obtained by transient torque-angle characteristic and equal area criteria. The influence of moment of inertia on dynamic stability is also discussed. Some useful conclusions are obtained.
