Coupled Vibration Analysis of Water Turbine Generator Unit and Hydropower Station House

Article Preview

Abstract:

The dynamic characteristics of shaft system in water turbine generating set and hydropower house structure is investigated by using the APDL procedure in ANSYS. The coupled vibration model which contains unit piers, hydropower house structure and water turbine generating set is developed. In this model, the nonlinear dynamic characteristics of the supporting structure (radial bearing) in water turbine generating set and the flexibility of unit piers and hydropower house structure are all considered. Through the revolving periodic transient results of the former four generating sets, the dynamic response of the shaft system in water turbine generating set and the dynamic characteristics of the hydropower house structure are analyzed. The interaction between the hydropower house structure and the water turbine generating set is discussed, which provide useful references to anti-vibration design of the hydropower house structure.
