Experimental study of a wind plant

Abstract

A statistical analysis of Wind characteristics and investigation of feasibility of wind energy for power generation has been conducted. Wind characteristics of different location e,g Teknaf, Mongla, Sandwip, Kutubdia and Comilla regions in Bangladesh have been analyzed and hence a compatible design of wind turbine applicable to the electric power generation has been performed specially for Comilla site. The available wind data collected by direct method through using anemometer, air flow meter and statistical wind data collected from weather station. By installing a prototype wind power plant electric power can be measured by using digital watt meter and AVO meter. From these data monthly average wind speeds have been calculated. It is observed that for some regions of Bangladesh, there is reasonable wind speed available throughout the year to extract power. From this data velocity frequency tables are shown and histograms have been plotted for every month for each location and compared with each other. The graph of power generation (W) versus wind speed (mls) have drawn with selected date wise. The wind energy concentration with different wind speeds has also been calculated Monthly extractable energy from wind as a source have been analyzed for several regions. Velocity duration curve and velocity frequency and energy histogram curve analyzed for Chittagong, Cox bazaar, Teknaf, Bagerhat and Patenga zone. For a prospective region of Bangladesh a wind turbine for electricity generation has been installed depending on topography of that region. This can also be used for any other region as well having the similar or above wind speed range. To present a generalized design for Bangladesh, an empirical relation may be developed for the wind turbine sizing and capacity selecting for a particular region of Bangladesh.
