Abstract
This thesis presents the development and implementation of a MATLAB-based model designed to represent the Power-Take Off (PTO) unit of the Maximal Asymmetric Wave Energy Converter (MADWEC) device. The objective was to create a model based on empirical data and mechanical principles to accurately represent a table-top prototype of the MADWEC PTO. This model will serve as a predictive tool, analyzing the performance of the PTO unit under various wave conditions and enabling the selection of optimal configurations based on the deployment location or power requirements. The computational model incorporates the PTO’s components, including a dual-dispensing reel, counterweight rewind mechanism, slip clutch, one-way clutch, gearbox, and generator. Leveraging the computational resources of MATLAB, the model accurately represents the prototype’s performance. The errors are minimal, ranging from 0.38% in tether force to 3.7% in motor torque, with an average error of 1.56%. This research details the development process of the model, including empirical data acquisition, analysis, and model optimization techniques. A performance estimation for the Nantucket Sound area indicated the potential energy generation capabilities of the device, estimated at approximately 0.19 kilowatts an hour or 1.664 megawatt-hours annually for that location. The study showcases a robust approach to predicting the efficiency and power output of MADWEC’s PTO unit, providing a valuable tool for researchers and engineers in the field of renewable energy. It contributes to the understanding of Wave Energy Converter (WEC) operations and supports the advancement of marine renewable energy systems by aiding in the design and optimization of WEC prototypes.
