Abstract
Gau is one of the many rugged, volcanic Islands in Fiji .Averaged 10 minutely wind speed and direction data of Vadravadra settlement was supplied by Fiji Department of Energy (DoE) and the site wind characterizing was done. Considering the surface roughness, obstacle condition and terrain information of the island, a micro-scale prediction has been done using the Wind Atlas Analysis and Application Program (WAsP) to develop an annual wind atlas and also a wind resource map which shows that at 50m height, the annual wind speed over Southern Gau varies from 8.42 to 14.69 m/s. The Southern Eastern sides of Gau appear to be promising for wind electricity generation using Vergnet 275 kW wind turbines where wind power density at a height of 50m or higher is found to be around 1128 W/m2 (average) annually. The total energy produced from using eight Vergnet 275 kW turbine generators was 13.320 GWh and the COE borne was $0.55/kWh.
Highlights
In light of the threefold global crisis mankind is facing currently – the energy crisis, the finance crisis and the environment/climate crisis – it is becoming increasingly obvious that wind energy offers solutions to all of these huge challenges, offering a domestic, reliable, affordable and clean energy supply
The primary use of Wind Atlas Analysis and Application Program (WAsP) has been for siting of wind turbines world-wide, single or in farms
WAsP predicts the resource assessment after the vector map and the wind atlas is inputted before calculation
Summary
In light of the threefold global crisis mankind is facing currently – the energy crisis, the finance crisis and the environment/climate crisis – it is becoming increasingly obvious that wind energy offers solutions to all of these huge challenges, offering a domestic, reliable, affordable and clean energy supply. This report examines the wind characteristics and potential power generation from wind at and around Vadravadra, the main settlement area in Gau using WAsP, a computer program used to calculate and determine potential of wind farming in a given area. The primary use of WAsP has been for siting of wind turbines world-wide, single or in farms Over the decade it has been in use, it has developed into a generally accepted standard for micro-siting [6]. Considering the effects for the obstacles, roughness and terrain, the WAsP develops a wind atlas for the region. The. wind atlas is used to predict the power density of the area in study and together with the resource grid, estimates the Net Annual Energy Production of any proposed turbine generator installations
