Optimized double sided linear generator for wave energy in São Paulo’s coast

Date: July 09, 2018 at 16:03 GMT

The main goal of this project was to design a linear electrical generator optimized to harvest energy from ocean surface waves of typical Brazilian shores, to assess its technical feasibility and to estimate its costs. We built a small scale model in order to test the proposed topology of an air cored double sided linear generator using NdFeB permanent magnets (PM). Next, we designed a full scale machine with rated peak values 5.09 kW and 107.3V. The cost of the electrical part alone is estimated in 8,460 Euros and the estimated levelized cost of electricity ( LCOE ) would range from 310.77 Euros/MWh to 772.76 Euros/MWh for a deployment off the coast of São Paulo state (SP).
