摘要
发生机电扰动时,汽轮机驱动转矩与发电机的电磁制动转矩之间失去平衡,使汽轮发电机组轴系产生扭振,是大容量柔性轴系面临的主要威胁之一。文章调查了国内外相关研究现状,总结了机网耦合与轴系扭振的关系,并给出了相关分析模型。
When electromechanical disturbance occurs,the unbalance of driving torque and the electromagnetic braking torque will happen. The torsional vibration,which threatens the large scale flexible shaft system,can be induced. The relative researches had been investigated,the relation between the mechanical side and electric side had been concluded,the model used for coupled effects analysis had been presented.
