AN INNOVATIVE WAVE ENERGY CONVERTER FOR MARINE DATA BUOY APPLICATIONS

Abstract

A current research focus is on how to give steady and dependable power to offshore equipment with unique power needs, such as marine data platforms and buoys that are located far from the coast. Most of these gadgets currently make use of photovoltaic power generation, high- capacity batteries, and routinely replace electrical supply systems. Wave energy is being examined as a solution due to the significant reliance of photovoltaic power generation on solar radiation and the expensive cost associated with frequent battery replacements. Wave energy converters (WECs) are machinery that transform wave energy into electrical energy. Their main benefit is a steady supply of electricity. In this study, a brand-new integrated wave energy converter for marine data buoys is proposed and examined. It has great dependability and low maintenance costs. A magnetic lead screw (MLS)-based direct-drive energy conversion unit serves as its central component. To maximise its power production, the device can passively track the buoy' s pitching status as it is being affected by waves. Voltage, current, and power for marine data buoys were measured using specific data values that were depending on the turbulence. In order to improve the system's accuracy and decrease power dissipations, artificial neural networks (ANN) are used. Using the necessary power for the data buoy and the remaining energy stored in the electric battery to power another marine system INDEX TERMS: - Oscillating-body buoy, magnetic lead screw, and wave energy conversion.
