The results of the analysis of oscillations of the structural elements of the Sayano-Shushenskaya HPP, caused by the influence of fluid pressure pulsations in water conduits, are presented. The connection between changes in the level of these fluctuations and loads of operation of hydraulic units is set. The load ranges of hydraulic units, leading to the formation of a vortex beam under the impeller of the hydraulic unit in the suction chamber and to resonant effects in the body of the dam are shown.
