摘要
阐述了大型汽轮发电机组轴系扭振与调速系统、电网系统、发电机励磁系统及电力系统稳定器间的耦合作用问题。分析耦合的形成机理以及对各系统性能的新要求，指出避免或抑制耦合作用的措施，并引用典型实例验证这些分析结论。同时介绍了汽轮机长叶片效应对轴系扭振特性的影响。
This paper elaborates on the couple problems between torsional vibration of large unit shaft system and governor system,exciter system and power systemstabilizer.The couple mechanism and its influence on the design for characteristics ofgovernor,exciter and stabilizer are analyzed.The measures to attenuate or eliminate thecouple effect are discussed and the corresponding typical examples are quoted to examine these conclusion. The effects of longer blade on the torsional vibration of shaft system are also included.
