  • Performance Analysis of Wind Turbines

    -

    I developed a research project to analyze the performance of wind turbines, as part of my internship in the course of Hydraulic and Wind Machines. Our main objective was to study the power coefficient curves in relation to the specific speed of wind turbines, considering variables such as blade pitch angle and incident wind speed.

    During the project, we carried out current and voltage measurements using an anemometer, and calculated the power generated by the wind turbines. We used tools…

    I developed a research project to analyze the performance of wind turbines, as part of my internship in the course of Hydraulic and Wind Machines. Our main objective was to study the power coefficient curves in relation to the specific speed of wind turbines, considering variables such as blade pitch angle and incident wind speed.

    During the project, we carried out current and voltage measurements using an anemometer, and calculated the power generated by the wind turbines. We used tools such as a tachometer and Microsoft Excel to measure the rotational speed and create power curves, which we then compared with the theoretical curves.

    Despite challenges related to the availability of accurate data and non-ideal measurement conditions, we were able to obtain meaningful results that physically resemble what was theoretically expected.

    This project provided valuable experience in the analysis of wind turbine performance and in the application of tools and methodologies for the evaluation of renewable energy systems.
