Practical notes on rotordynamics of power generation trains

Abstract

The purpose of this article is to provide new practical guidelines on rotordynamics and stability analysis of power generation trains. Latest methods, modern recommendations, recent lesson learned and new practical notes on power generation machinery rotordynamics are presented. Critical areas relative to safety and reliability of power generation machine design and component selection including the bearing dynamic effects, the rotordynamics study/modelling methods, the third party analysis, the gear unit dynamic and potential instability sources are discussed. The main concern is the correct design and dynamic study of a power generation train before the equipment fabrication and the component sub-supply started and for some issues even before the train order. Case studies are also presented.
