Development of an Electrical Generator Optimized for Wave Power Generation

Abstract

Wave energy stands out as a strong source of renewable energy with its high energy density. Current methods of converting the mechanical energy stored in waves to electrical energy—referred to as power take off (PTO) systems—often transform the low-speed, high-torque input from waves into a high-speed, low-torque output to operate a conventional generator. However, these PTOs reduce the overall efficiency of wave energy converters (WECs), and add cost to the manufacture and maintenance of WECs. As a result of these issues, we are designing a generator and a drivetrain system that is optimized to deliver maximum efficiency when operated under low-speed, high-torque conditions. The final deliverable of this project will be a design of generator and drivetrain system verified through low-fidelity MATLAB simulation and high-fidelity Finite Element Method Magnetics (FEMM) simulation.
