Designing a stand-alone wave energy generation system

Renewable energy in the most popular sector with the increasing research to use due to its abundance. However, the setback lies amongst the inability within the existing system to tap the humongous potential within such forms of energy. One such undermined source is wave energy. This paper suggests a method of optimizing the efficiency of energy generated from waves using power electronic devices and efficient designing of the turbines. The quantity of electrical energy generated by the waves will then act as a governing criterion for operation of entire system. The Periodic motion of waves is captured via float-reciprocating pump arrangement and converted into the rotational motion of the turbines. The turbine is designed to withstand the intense pressure of the waves imparted on its surface. The structure of the turbine is designed where the analysis is performed in the domain of shear and thermal stresses caused by the waves. The turbine then produces electricity, as it is generated from a three phase Induction generator connected to the turbine. Three phase Rectifier circuit is designed in such a way to convert to AC output from wave energy generator to the pulsating DC parameters, further passing through Converter circuits which is then stored in battery. The system utilizes efficient tapping of the wave energy along with reducing the fluctuations produced in the generated output of such a system. The converter used here limit the fluctuations in output voltage by efficiently performing voltage amplification and sending a regulated output at rated values to the storage battery. Additionally, the stored energy in battery is used for lighting LED panels at shore, acting as safety lights for boats and ships.
