Problems of Turbine Generator Shaft Dynamics
The nature of faults and disturbances which can occur in an electrical power system are reviewed. The sequence of events to which a turbine-generator unit may be exposed from such events is described. Procedures for unit response analysis are mentioned, and current problems in predicting such response are discussed. The need for on-line shaft monitoring and cumulative damage analysis is mentioned. Several types of continuous monitoring and measurement equipment now in use on turbine-generators are described, with details of their performance. Conclusions are presented concerning the state-of the-art in this area.
