汽轮发电机组轴系暂态扭矩响应的简化分析

Simplified Analysis of Response of Transient System Torques on Turbo Generator Shaft

通过对轴系暂态扭矩分析采用的简化方法,是将暂态电磁矩模型直接加到轴系的机械模型中的分析,得出有关结论。证明了非同期合闸对轴系造成的最大扭矩并非发生在合闸角为120°时。

This paper presents a simple analytical method to study the transient torque on the shaft. That is to apply a transient electric magnetic torque directly to the mechanical model of the shaft system. Related conclusions are drawn, and found that the maximum torque to the shaft system during nonsynchronous closing of CB is not at 120°.
