Investigation and assessment on potential of wind energy in the central region of Thailand
Abstract:
In this paper, both wind energy resource and financial feasibility are mainly investigated to assess potential on electrical energy production of wind turbines in the central region of Thailand. Wind maps and field surveys are employed as technical tools to decide on suitable locations of wind masts. Accordingly, one-year wind data is collected from three ultimately selected sites of wind masts at Ratchaburi (S1), Pathum Thani (S2), and Saraburi (S3), which are all the provinces in the central region of Thailand. For each site, wind speed and direction are measured at three levels: 65 m, 90 m, and 120 m from ground level with a sampling rate of one minute. The data set is applied to the WAsPTM program for wind data analysis. It is found that annual mean wind speed is more and less between 3 and 5 m/s at each site. Also, the Weibull distributions of wind data are reported. Annual energy productions, which are generated by BonusTM 1 MW wind turbines at heights of 65 m, 90 m, and 120 m, are determined to be (255 ; 338 ; 465) MWh, (329 ; 426 ; 574) MWh, and (493 ; 633 ; 829) MWh for the sites S1, S2, and S3, respectively. In another matter, Carbon credit sale and effect of reduced import crude oil are considered in economic analysis. In feasibility analysis, none of potential sites for generating wind energy with large wind iv turbine seems to be attractive. As a result of that, factors such as design, capacity, rotor diameter and technology of wind turbines for different brands are analyzed with satisfactory financial indicators under rational scenarios in this study. In final, VestasTM V60 850 kW wind turbine is considered as the most suitable one among available turbines for the concerned region. Lastly, good agreements between financial and economic analysis are presented to insist great feasibilities on electrical energy production from wind energy in the central region of Thailand
