Ocean Tidal Power Generation

Abstract

Non-conventional power sources are freely available from nature and is available in abundant quantity. Given the drawbacks of its counterpart conventional sources of coal and fossil fuels are on verge of extinction and creates pollution, more and more research is done on the non-conventional or renewable sources like solar, wind, tidal, etc. With this project we plan to introduce a new way of harnessing wind power, hydro power and ocean power from a single pole inside an ocean. One will be our regular wind turbine at the top most part much above the ocean water, generating power through wind turbine.

The middle part of the pole will generate electricity through hydro power turbine rotated through the moving water stream. Final will be located inside the ocean, on both sides of the pole due to the water movement little

above the water bed. This project can be seen generating more power on a single pole, thus when implemented on a large scale can generate enormous power to fulfill the rising demand of electricity for everyone.

Moreover, it will do so at the cost of no extra land whose rates are high.

INTRODUCTION

Wave power is the capture of energy of wind waves to do useful work – for example electricity generation, water desalination or pumping water. A machine that exploits wave’s power is a wave energy converter (WEC).

Wave power generation is not a widely employed commercial technology, although there have been attempts two use it since at last 1890.

Working

When the air moves above the sea level, in the open space, it exerts a force on the wind turbine blades.

This blades are coupled with the shaft of the generator, Thus they also start to rotate. Due to Faradays law of electromagnetic induction, emf is induced into the conductor, Thsu generating the electricity.

When the ocean water flows in the form of tides, they move up and down continuously, with enormous amount of force. This force in forward direction is used to exert a force on the hydro turbine blades.

Here also the turbine is coupled with the generator shaft which again generates electricity with the same principle of electromagnetic induction. Similar action takes place inside the ocean also at the bottom part. It generates power with the same action of water force, but the pressure of water is low over here compare to the tides at up. Hence the power output is low from one turbine, for this reason we have planned to install 2 turbine blades on both sides of the pole.

In this way, a single pole can be made to harness power from multiple sources and generate more

Working

• Horizontal axis wind turbine (5 blades)

This will be present at the middle part of the pole just above the water level. The flowing water will rotate the turbine.

• Horizontal axis wind turbine (3 blades)

This will be present at the top most part of the pole. It will be rotated by the air flow acting as a wind turbine.

• Vertical axis wind turbine (4 blades)

This will be present under the water just below the water level. It will be rotated with the help of water movement alongside or un-uniform motion.

• DC generator (Dynamo) 12volts. (3 nos.)

This will be coupled with each turbine to generate the DC power output depending upon the rotation speed of the turbine. Faradays Law will be used over here.

Multimeter

Multimeter will be used to display the values of voltage output of various sources at various speeds.

PVC pipe

This will be used for supporting the whole structure in our project

Problem Statement

Electricity demand is increasing exponentially in comparison to the generation, thus we are facing shortage. Also apart from infrastructure cost, the cost of land is more and is available in limited quantity. Wind power plant needs to be installed in open space, which limits the infrastructure development in that area in future. Ocean space in the world is available in 78% of earth. Given, the limitation of land, we failed to utilize the space of ocean for any other need.

Objective

Try to utilize the ocean space for setting up power generation infrastructure without incurring the heavy initial cost of land. Make use of single pole for multiple types of power generation, namely wind, hydro, tidal.

Try to provide a solution by reduce the strain on the land requirement for setting up such large type of wind turbines.

Scope

This type of power generation will reduce the infrastructure cost associated with setting up of the wind turbines. Reduces the strain on the land requirement. Since the space is available in large quantity on the earth, it holds a large potential to generate electrical power

Advantages

• The power can be generated at no extra cost of land which is already very high on earth land.
• More power can be generated in compared to the single power generation source in per quantity of area.
• Different type of sources will ensure 24 hours power generation since, any one of them will be definitely available to generate power.
• No disturbance to the flying birds, since such birds are absent at this distance away from seashore.
