SEMINAR ONWAVE ENERGY CONVERTER (Non conventional energy source)By, G.Satish babuP.prakash

INTRODUCTION

-80% of power needed is generated from fossil fuel.

-Research is going on for the last 30 years on different kind of WEC

-Two types of wec utilizing vertical force of wave are: 1. Point absorber driven linear generator 2.Floating wave energy extractor

The rising and falling of the waves offshore causes the buoy to move freely up and down |The resultant mechanical stroking drives the electrical generator | The generated AC power is converted into high voltage DC and transmitted ashore via an underwater power cable POINT ABSORBER DRIVEN LINEAR GENERATOR

FLOATING WAVE ENERGY EXTRACTORABOUT THE TECHNOLOGY

The system consists of a rectangular shaped huge mass floating body supported by a large number of floating air columns. The air columns extensions are connected to pistons. The pistons are placed its own cylinders and it can move up and down through the cylinders when the floating air columns moves with the up-down movements of the waves

FLOATING WAVE ENERGY EXTRACTOR

COMPONENTS-HUGE MASS FLOATING BODY-THE PIPE SYSTEM FOR THE HYDRAULLIC FLUID-FLOATING AIR COLUMNS-AIR TIGHT FLUID TANK-THE ANCHORS-POWER TRANSMISSION EQUIPMENTS

WORKING

UNIQUE FEATURES-CAN BE INSTALLED ANYWHERE THERE IS SUFFICIENT WAVES REGARDLESS OF THE DEPTH OF THE SEA

-SYSTEM REQUIRES NO DIRECTIONEL WAVES

-RISK OF CORROSION IS REDUCED

-TIDAL ACTIVITIES WILL NOT CAUSE ANY OPERATIONAL PROBLEM

Worldwide Wave Power Levels (kW/m of Wave Front)

-Relatively easy to build and install

-requires only regular low cost maintenance for a life time of 30 years

-power can be fed immediately into the power grid or stored -Scalable to high capacity power stations(100MW+)

-Production cost is highly competitive against conventional sources of power

ADVANTAGES

ENVIRONMENTAL ADVANTAGES- NO WASTE IS PRODUCED

- NO POLLUTION

- REDUCE SHORELINE EROSSION

- WHEN A100MW CONVENTIONAL POWER PLANT NEED 2 SQUARE MILES OF LAND A WEC PLANT NEEDS LESS THAN A SQUARE MILE OF OCEAN

DRAWBACKSHIGH INVESTMMENT COST

-SURVIVABILITY OF THE PARTS EXPOSED TO THE LARGE POWERS OF THE OCEAN

CONCLUSION WAVE ENERGY FORMS THE MOST DEEPLY POWERED NATURAL RESOURCE WHICH CAN BE DIRECTLY USED FOR ENERGY GENERATION

-WAVE ENERGY WILL BE A MAIN SOURCE OF POWER IN THE FUTURE
