Analysis of the Resonance Phenomena in the Operation of the Lower Bureya HPP During an Earthquake

详细

To justify that hydroelectric power plants operating in seismic areas are safe, it is necessary to analyze the resonance phenomena in the generating unit. The analysis was performed using a finite-element model of the powerhouse-foundation-equipment system of the Lower Bureya HPP. The resonance phenomena occurring when the disturbance frequency at the elevation of the stator supports is close to the first natural frequency and speed of the water turbine were studied.
