The Vibration Characteristics of the Hydropower Plant with a Certain Cross Flow Hydro-Turbine Generating Units and its Earthquake Response Analysis

Abstract:

To consider the safety of a certain cross flow hydro-turbine generating units and the hydropower plant, the finite element model of the plant and units are established by ANSYS, with which the resonance check is carried out. Meantime, the spectrum analysis method is used to present an earthquake response analysis according to the relative specifications, and the earthquake reaction condition in different directions of the characteristic monitoring points in main height is obtained, then the vibration characteristics of the hydropower plant and the effect of the earthquake load are analyzed. The research gives evidence and reference to make sure of the plant structure safety and the healthy operation for hydro-turbine.
