摘要
从电机的基本方程出发,推导出了大型同步电机在功角作正弦小振荡时的电磁转矩的变化,根据整步转矩系数与阻尼转矩系数的定义,给出了大型同步电机整步转矩系数与阻尼转矩系数的表达式,计算出了大型同步电机整步转矩系数和阻尼转矩系数。
In this paper, the change of electromagnetic torque under small sinusoidal oscillation is deduced from the fundamental equation of synchronous generator, and the expressions of synchronizing torque coefficient and damping torque coefficient are presented according to the definition of synchronizing torque coefficient and damping torque coefficient. Besides, the synchronizing torque coefficient and damping torque coefficient of the large synchronous machine are calculated.
