Abstract

Due to the continuous fluctuation of the prices of oil and the environmental impact on the economy, a renewable energy becomes debatable issue. The generation of electricity by harnessing the power of sea wave has been the most prominent research into renewable energy for over decades. Various researches have used various power take off mechanisms systems for converting wave power into electrical power such as the pelamis, oscillating water column, Archimedes wave swing etc. In this research, linear generator power take of method is used to convert the motion of wave at its interaction with the devices into electricity since this method offers a great power output at a minimum wave energy power than other methods. Feasibility studies to ascertain the exact location for mooring of the components were conducted using google search. The analysis of a hybrid quantitative and qualitative method is applied. In this aspect, statistical analysis of sea wave data and the consumption of electrical gadget of the faculty engineering of Regional Maritime University were analysed in order to design a suitable wave energy converter. Hydrodynamic analysis of wave energy converter was determined in order to establish the velocity of sea wave, for due to the incident wave, the energy from sea wave and the electrical power generated by the generator as a result of sea wave energy.

Highlights

  • As fossil fuel is the main source of energy supply to the world’s economy or the earth population [1], the world faces future energy challenges

  • Power take off system can be oscillating column of water, wave dragon system and underwater pneumatic system deep water and are being moored to the sea floor and these devices represent the promising class of wave energy converters [10]

  • In order to develop a more appropriate design, calculations have to be done to investigate the total amount of electrical power fed into the transformer and the maximum wave power extracted by the Wave Energy Converter (WEC) device with different wave height and periods by simulating

Summary

Introduction

As fossil fuel is the main source of energy supply to the world’s economy or the earth population (approximately 82%) [1], the world faces future energy challenges. The increase in growth of human population and the demand for energy consumption rate will cause fossil fuel known to exist but not currently exploit to be depleted within decades. Due to the continuous fluctuation of the prices of oil and the environmental impact on the economy, a renewable energy becomes debatable issue. The generation of electricity by harnessing the power of sea wave has been the most prominent research into renewable energy for over decades. Simple modern WECs are design and tested to have higher efficiency that can stop 90% of the wave motion and convert all the wave motion to generate electricity given 81% efficiency [6]. This research is intended to carry a Journal of Electrical and Electronic Engineering 2017; 5(4): 130-140 feasibility study for a possible Wave Energy Converter (WEC) at the shore of the University to generate electricity to run day to day activities of its faculty of Engineering
