Vertical-Axis Wind Turbine for Domestic Use Power Generation
摘要
Despite promising global research on wind energy for electricity generation, small wind turbine projects remain scarce in Palestine. Multiple challenges—including political barriers, high costs of wind turbine infrastructure, and limited availability of suitable land—have hindered the development of wind energy systems in the region. Moreover, the generally low wind speeds in Palestine reduce the efficiency of traditional horizontal-axis wind turbines (HAWTs). This study investigates the feasibility of using small vertical-axis wind turbines (VAWTs) for domestic and agricultural applications in Palestine. Four years of wind speed data from six locations in the West Bank were analyzed using the Weibull distribution and MATLAB to evaluate the potential of small-scale wind energy systems. A 600-W VAWT was also constructed and tested under real-world conditions. Simulation results indicated that, under favorable conditions, the turbine could generate up to 50 kWh per month; however, in less optimal locations such as Tulkarem, expected output may be as low as 10 kWh monthly. Laboratory wind tunnel testing yielded a maximum power output of approximately 35 Wh. These findings suggest that while small wind turbines offer promise in specific settings, their practical performance is highly site-dependent.
