Dynamical Analysis on Underground Powerhouse of Yixing Pumped-Storage Power Station

Abstract:

The vibration characteristics and vibration response under different load cases in the underground powerhouse structure of Yixing pumped-storage power station were studied by establishing three-dimensional finite element model. The harmonic and transient analysis methods were proposed to study the vibration response of the powerhouse structure under various generating unit dynamic loads and in transient process. The numerical results were evaluated according to the related rules and regulations. The result shows that the vibration response of the power house structure is in the limit of the rules and regulations and there was little chance of resonance.
