DYNAMICS OF WAVE GENERATOR WITH NON-CIRCULAR FLOAT ON A PLANE WAVE

The paper presents one of the most important areas of alternative energy which is the use of the sea wave power. This area is more promising in comparison with the solar energy generators and the wind ones, since the energy flux density of sea waves is much larger than the flux density of solar and wind energy. With the same power of electric power sources, the size, and hence the cost of generators, used wave power, are significantly less than that of wind generators and generators using solar power. The paper suggests a float wave generator for autonomous energy consumers located about water areas away from the centralized power supply and considers the mathematical model of a wave generator with a non-circular crosssection float, based on the use of the equations of dynamics and electrodynamics. Under the influence of waves, the float performs a reciprocating motion. This motion is converted into rotational motion and transmitted to an electric generator that generates an electric current. The model is described by a system of differential and algebraic equations that reduce to a second order ordinary non-homogeneous differential equation. In order to solve the differential equation for the main parameters of the generator, it is developed the software that implements the calculation of the average power of the wave generator and performs optimization of its parameters based on the implementation Runge-Kutta and Simpson methods. When calculating the average power of a wave generator, the following parameters are taken into account: gravity force, Archimedes force, spring elastic force, drag force, length and amplitude of the incident wave, float mass and generator characteristics
