Yttrium Barium Copper Oxide Superconductor Used in a Linear Generator for High Power Generation from the Oceanic Wave

Most of the existing linear generator uses ordinary copper winding that results in low amount of electrical power generation from the oceanic wave. This paper proposes a high performance permanent magnet flux switching linear generator (PMFSLG) in which a high temperature superconductor, yttrium barium copper oxide is used for winding. The generated voltage, load current, magnetic flux linkage, and output power of the PMFSLG are shown in detail. The finite element method is used by ANSYS/Maxwell simulation software and the results show that, the proposed PMFSLG has better flux linkage, can generate more output voltage and power than that of the conventional one.

I. Introduction

The increase of electricity generation is very significant to fulfil the global demand. There are different types of sources to generate electricity such as fossil fuel, renewable energy resources etc. Many countries have used fossil fuels as the main source of the extraction of electrical energy which is the global warning owing to the pollution of environment [1]. On the other hand, renewable energy resources are the clean and pollution free sources [2]. Hence, the renewable energies are needed to be applied in order to produce electricity instead of fossil fuels. At present, solar [3], wind [4], and oceanic wave energy (OWE) [5] are used as renewable energy. Out of these, OWE contains much energy density [6]. For this reason, large amount of electricity is possible to produce from it.
