Summary

 
Object and purpose of research. The object of the study is the wave energy converters (WEC) into electric power. The purpose of the study is to draw up a differential equation describing the operation of the WEC, its solution and determination for the design parameters influence of the WEC on the efficiency of energy conversion
Subject matter and methods.The theoretical methods adopted in ship mechanics and theory are used to study the operation of complex mechanisms and dynamics of marine objects. The data on the characteristics of electric generators are used
Main results. The differential equation describing the operation of the WEC on regular wave is compiled. The equation relates the characteristics of waves to the design parameters of the WEC. Generalized characteristics of electric generators are obtained. Systematic calculations are carried out; they show the influence of the WEC design parameters on the efficiency of wave energy conversion into electric power.
Conclusion. The results can be used in design of the WEC. The resulting differential equation makes it possible to investigate the operation of the WEC in various marine conditions and to evaluate the influence of design parameters on the efficiency of energy conversion. The generalized characteristics of electric generators can be used in design of wave power structures and wind power plants.
