摘要
大型汽轮发电机组运行中,因次同步谐振(SSR)或次同步振荡(SSO)发生的扭振损坏是电力工业大机组与大电网发展时期的常见问题。多年来,扭振事故导致汽轮发电机组及电力设备多次严重损毁,一直被世界各国关注。经过多年对发电机组轴系结构特点和网机关系的分析研究,目前抑制或消除扭振故障的措施已取得重要进展和实效。分析了伊敏电厂600 MW发电机组扭振损坏问题,为出现类似问题的机组提供参考。
Tortional fatigue damage of large turbogerator set, caused by SSR or SSO, make great damage on set and elecertric equip- ments. For a long time, it becomes a hot issue in all around world. As a result on study of the shaft system structure and gereator-net- work harmonization, obtained obvious progress and substantical resuh are obtained on suppress and elemination for tortional damage. The paper analyses the problem of tortional damage for 600 MW turbogenerator of YM power plant, providing a reference for the similar problem of set.
