Abstract :

In our work, we conducted a comprehensive analysis comparing the experimental results with the modeled performance of a wind turbine located in the Naaama site in Algeria. Our primary objective was to evaluate the effectiveness and accuracy of the model in predicting the behavior of the wind turbine under real-world conditions. To begin, we calculated the wind speed variations throughout the year at the Naaama site. This involved collecting meteorological data and employing mathematical calculations to determine the average and fluctuation patterns of wind speeds. Simultaneously, we carried out practical measurements of the power output using an actual wind turbine installed at the Naaama Center University, specifically the Salhi Ahmed facility. Next, we employed a sophisticated program to model and simulate various physical parameters associated with the wind turbine. This encompassed factors such as blade length, turbine height, rotor diameter, and generator efficiency, among others. By inputting the meteorological data and the turbine's specifications into the program, we obtained a simulated performance profile of the wind turbine under different wind conditions. To validate the accuracy of the model, a second set of experiments was conducted in the laboratory. These experiments involved subjecting the wind turbine to controlled wind speeds and comparing the obtained results with the model's predictions. The outcomes of this test indicated a close alignment between the experimental and modeled data, reinforcing the reliability of the model. Additionally, we explored the optimization of the wind turbine design by investigating the ideal radius and the number of blades. Through extensive analysis and simulations, we evaluated various combinations of blade lengths and numbers to determine their impact on the turbine's performance. This endeavor aimed to enhance the overall efficiency and electricity production capacity of the wind turbine. The results obtained from the Naaama site exhibited a significant level of satisfaction regarding the electricity production capabilities of wind farms. The comparison between the experimental and modeled data showcased a high degree of correlation, affirming the validity of the model and its potential applicability in other wind energy projects. Overall, our work involved a thorough examination of the wind turbine's performance through a combination of experimental measurements, mathematical modeling, and simulation techniques. The findings contribute to the ongoing efforts to harness renewable energy sources, particularly wind power, for sustainable electricity generation. 摘要： 在我的工作中，我进行了一项综合分析，比较了位于阿尔及利亚的纳马（Naaama）站点的实验结果与风力发电机的建模性能。主要目标是评估模型在真实环境条件下预测风力发电机行为的有效性和准确性。 首先，我计算了纳马站点一年中的风速变化。这涉及收集气象数据，并进行数学计算，以确定风速的平均值和波动模式。同时，我利用安装在纳马大学萨利阿赫迈德中心的实际风力发电机进行功率输出的实际测量。 接下来，我使用先进的程序对与风力发电机相关的各种物理参数进行建模和模拟。这包括叶片长度、涡轮高度、转子直径和发电机效率等因素。通过将气象数据和涡轮规格输入程序，我得到了在不同风力条件下风力发电机的模拟性能概况。 为了验证模型的准确性，进行了第二组实验，这些实验涉及将风力发电机置于控制风速下，并将实验结果与模型的预测进行比较。这些测试的结果显示实验和模拟数据之间存在密切的一致性，证实了模型的可靠性。 此外，我还研究了风力发电机设计的优化，通过调查理想的半径和叶片数量来实现。通过广泛的分析和模拟，我评估了不同叶片长度和数量的组合对涡轮性能的影响。这项工作旨在提高风力发电机的整体效率和发电能力。 纳马站点的结果显示，人们对风力发电场的电力生产能力非常满意。实验和模拟数据之间的比较显示了很高的相关性，证明了模型的有效性及其在其他风能项目中的潜在适用性。 总的来说，我的工作通过实验测量、数学建模和仿真技术的结合，对风力发电机的性能进行了全面的研究。这些发现为利用可再生能源，特别是风能，进行可持续电力生产的不断努力做出了贡献。
