Research Progress in Vibration Suppression Technology for the Unbalance Fault and Rotor Shaft System of Turbin Generator Set
Turbo-generator set is a typical high-speed rotating machine.With the increase of energy de-mand and unit capacity,the unbalanced vibration becomes an important factor affecting both reliability and stability of the operation.In this paper,the structural characteristics of two commonly-used rotor shaft sys-tems were analyzed,and both mechanism and influencing factors of the rotor unbalance vibration were summarized through analyzing practical engineering cases;meanwhile,the research progress in unbalance fault vibration treatment methods and self-healing control technology was investigated to look into the de-velopment direction of unbalance self-healing control technologies.
