ABSTRACT

This study aims to evaluate wind resource potential and analyze the performance of wind turbines for six onshore and near-coast sites (three commercial power plants and three new potential sites) of Pakistan. The technical and economic performance analysis of more than 200 commercially available turbines suitable for weak wind regions is performed, 20 turbines were selected based on performance. The percentage increase in annual Capacity Factor (CF) and decrease in Levelized Cost of Electricity (LCOE) for commercial sites using proposed turbine is 42–61% and 30–38% respectively compared to installed turbines on the sites. Three potential sites have wind power density as 155, 203, and 237 W/m² and corresponding wind power class as poor, marginal and marginal respectively. The CF and LCOE of potential sites having marginal power class using PT10 turbine (Goldwind GW140/3.0) is up to 50% and 5.5 US¢/kWh respectively so these two sites are economically feasible for future wind projects. The CF and LCOE of potential sites having poor power class using PT10 turbine is 34% and 7.2 US¢/kWh. The wind turbines having lower cut-in wind speed and lower-rated wind speeds are economically feasible for sites having poor wind power class.

摘要

这项研究旨在评估风能潜力，并分析巴基斯坦六个陆上和近岸站点（三个商业发电厂和三个新的潜在站点）的风力涡轮机性能。对200多个适用于弱风地区的商用涡轮机进行了技术和经济性能分析，根据性能选择了20台涡轮机。与安装在现场的涡轮机相比，使用拟议涡轮机的商业场所的年容量因子（CF）的增加百分比和平均电力成本（LCOE）的减少分别为42–61％和30–38％。三个潜在站点的风电密度分别为155、203和237 W / m ²以及相应的风力等级分别为差，边际和边际。使用PT10涡轮机（Goldwind GW140 / 3.0）的具有边际功率等级的潜在站点的CF和LCOE分别高达50％和5.5 US¢/ kWh，因此这两个站点对于未来的风力发电项目在经济上是可行的。使用PT10涡轮机的潜在功率等级较差的潜在站点的CF和LCOE为34％和7.2 US¢/ kWh。具有较低的切入风速和较低的额定风速的风力涡轮机对于风力等级差的地点在经济上是可行的。
