摘要
本文用状态方程研究、计算了定子电阻对同步电机正弦稳态大振荡时整步转矩及阻尼转矩系数■_S、■_D的影响。算出了一族典型参数的■_S、■_D值随定子电阻的变化曲线,供设计、研究和实际运行时使用。
In this paper, the synchronizing and damping torque coefficients of synchronous machines considering the effect of stator resistance on it under large sinusoidal oscillation are calculated with state equations of incremental form. The curves of ■_S, ■_D of the synchronous machines with typical parameters as a function of stator resistance are given for engineering use.
