One of the urgent tasks of using renewable energy sources is the use of a power unit for converting the energy of sea waves into electrical energy. An important element of the design process of a wave power plant is to carry out mathematical modeling of its operation under various operating conditions to determine the output power and conduct a feasibility study. The process of converting the energy of sea waves into electrical energy for the proposed type of wave power plant is based on forced vertical oscillations of the power unit's float caused by sea waves. The mathematical model of the behavior of the float connected to the generator is based on the integro-differential equation of forced oscillations and makes it possible to determine the dynamics of its oscillations and draw a conclusion about the power taken from the generator connected to the float. The article presents the calculations of the dynamics of the float connected to the generator, the wave equation, the integro-differential equation of the float oscillations, the modeling of the incident wave and the float power unit is carried out. Data on the length, period and height of waves in the Black Sea off the coast of Crimea are used according to official forecasts and observations.
