ABSTRACT

The generation of electricity from wind energy can reduce the fossil sources imported and carbon dioxide emissions. The wind is free, clean, and green energy. This study aims to present a wind energy assessment for Mukdahan site of Thailand. The wind speed at heights of 60, 90, and 120 m above ground level was measured from January 1^st, 2012 to December 31^st, 2017. The annual mean wind speeds were 3.59, 4.02, and 4.51 m/s at 60, 90, and 120 m AGL, respectively. The majority of wind directions were contributed by the monsoon for this region. The Wind Atlas Analysis and Application Program (WAsP) was used to predict the Annual Energy Production and Capacity Factor for five selected wind turbines in a capacity range of 0.85 − 3.30 MW. Moreover, the high-resolution wind resource map also indicated the high potential for wind around the site. The low cut-in speed and high hub-height wind turbines such as VestasV110-2.0 MW and V126-3.3 MW can produce higher energy output, capacity factor and better cost of energy, especially when the wind turbine site is located on the ridges and peaks of hills around the site. The best cost of energy was 0.030 USD/kWh, which was observed for the V110 wind turbine and the second best was 0.041 USD/kWh for the V126 wind turbine, especially when considering placement on the peak of a hill. The important data from this study can be developed for wind farm project installation and suitable wind turbine design for the whole local region.

摘要

风能发电可以减少化石能源的进口和二氧化碳的排放。风是免费、清洁和绿色的能源。本研究旨在对泰国 Mukdahan 场地进行风能评估。2012年1月1^日至12月31^日测得的海拔60、90、120 m高度风速, 2017. 60、90 和 120 m AGL 的年平均风速分别为 3.59、4.02 和 4.51 m/s。该地区的大部分风向是由季风引起的。Wind Atlas 分析和应用程序 (WAsP) 用于预测容量范围为 0.85 - 3.30 MW 的五个选定风力涡轮机的年度能源生产和容量系数。此外，高分辨率的风资源图还表明该站点周围的风潜力很大。VestasV110-2.0 MW 和 V126-3.3 MW 等低切入速度和高轮毂高度的风力涡轮机可以产生更高的能量输出、容量系数和更好的能源成本，尤其是当风力涡轮机站点位于山脊和场地周围的山峰。最佳能源成本为 0.030 美元/千瓦时，观察到 V110 风力涡轮机和第二好的 V126 风力涡轮机为 0.041 美元/千瓦时，尤其是在考虑放置在山峰上时。本研究的重要数据可用于风电场项目安装和适合整个当地的风力涡轮机设计。
