Analysis of Weibull parameters for the three most prospective wind sites of Bangladesh

The present demand for energy is increasing day by day due to various reasons such as increasing population the aspiration for improved living standards and general economic and industrial growth. In the wake of the increasing world energy crisis, which mostly affected the least developed countries, the interest in alternative energy resources has been increased considerably. In this regard, wind as a source of energy can hold good prospect for an underdeveloped country like Bangladesh. Besides, utilization of wind energy has been growing rapidly in the whole world due to environmental pollution, consumption of the limited fossil fuels and global warming. Bangladesh has fairly wind energy potential, exploitation of the wind energy is still in the crawling level. In the current study, wind characteristics and wind energy potential of (KKK) Kuakata, Kutubdia, and Khagrachari in the Coastal Areas are investigated. First of all the wind data of the coastal areas in Bangladesh from January to December, 2006 is to be collected and sorted in sequence in appropriate frequency. The data are further analyzed and converted into several useful parameters, like daily mean wind speed, monthly mean wind speed, and mean annual wind speed. After that, the velocity frequency bar graph, energy bar graph, velocity duration curve, etc. have been plotted and analyzed. The wind speed data of a location has been fitted to Weibull function to find different parameters for that site. The value of the Weibull shape factor (k) and Weibull scale factor (c) have been calculated by different methods and compared and plotted them by employing different methods. Then a Wind Turbine has been designed for an effective location for electricity generation in Bangladesh
