INTERACTION OF GRAVITY WAVES WITH TIDAL POWER PLANT
Abstract
The use of renewable energy sources is urgent and relevant in the life of humanity in the current conditions of fuel and energy crisis and environmental pollution. One type of renewable energy source is tidal power plants, which use the potential energy of tides. Determining the features of the interaction of the wave flow with the designs of the tidal power plant and the creation of conditions for trouble-free and efficient operation of such stations is certainly an urgent problem in modern power engineering. The purpose of the research is to determine the effect of gravitational waves on the design of a tidal power plant and to develop recommendations for safe operating conditions of the tidal power plant. Numerical and experimental studies of the interaction of the wave flow with the structures of the tidal power plant and the dam enclosing the closed water area are conducted in this work. For this purpose, a modern apparatus of theoretical hydromechanics, probability theory and mathematical statistics was used, an experimental stand was created and laboratory studies were conducted in a wave pool, where a wave generator generated gravitational waves of the given parameters. Visual studies have been conducted and the integral and spectral characteristics of velocity and pressure fields have been determined. The hydrodynamic characteristics of wave motion and flows through the turbine tracts of a power plant and their spectral components are obtained. Pressure fields, loads and torque moments on the building of the station have been determined, and features of soil erosion at the junction of the station and the bottom of the reservoir have been established. Sandy soil erosion characteristics near the tidal power plant were evaluated. Recommendations were made regarding the trouble-free operation of the tidal power plant and the optimal thicknesses of the sand cushion and stone berm on which the station was built. Ref. 20, Fig. 5.
