Spectral Analysis of Pressure Fluctuations in the Water-Conducting Channel of the Turbines and the Resulting Vibrations of Building Structures of Service Units of the Building of the Sayano-Shushenskaya HPP.

The article analyzes the amplitude spectra of vibrations of building structures along the water intake and outlet pipe of the SShHPP unit, and determine the components caused by pressure pulsations along the length of the water supply path, including the outlet pipe. The effect of the turbine's operating mode is shown, as are the criteria for the removal of loads from disturbances and hydro-acoustic standing waves. [ABSTRACT FROM AUTHOR]
