Özet

Wind turbine technology in the world has been developed by continuously improving turbine performance, design, and efficiency. Over the last 40 years, the rated capacity and dimension of the commercial wind turbines have increased dramatically, so the energy cost has declined significantly, and the industry has moved from an idealistic position to an acknowledged component of the power generation industry. For this reason, a thorough examination of the aerodynamic rotor performance of a modern large-scale wind turbine working on existing onshore wind farms is critically important to monitor and control the turbine performance and also for forecasting turbine power. This study focuses on the aerodynamic rotor performance of a 3300-kW modern commercial large-scale wind turbine operating on an existing onshore wind farm based on the measurement data. First, frequency distributions of wind speeds and directions were obtained using measurements over one year. Then, wind turbine parameters such as free-stream wind speed (U-infinity), far wake wind speed (U-W), axial flow induction factor (a), wind turbine power coefficient (C-P), tangential flow induction factor (a '), thrust force coefficient (C-T), thrust force (T), tip-speed ratio (lambda), and flow angle (phi) were calculated using the measured rotor disc wind speed (U-D), atmospheric air temperature (T-atm), turbine rotational speed (Omega), and turbine power output (P) parameters. According to the results obtained, the maximum P, C-P, C-T, T, and Omega were calculated as approximately 3.3 MW, 0.45, 0.6, 330 kN, and 12.9 rpm, respectively, while the optimum lambda, phi, U-infinity,U- and Omega for the maximum C-P were determined as 7.5-8.5, 6-6.3 degrees, 5-10 m/s, and 6-10 rpm, respectively. These calculated results can contribute to assessing the economic and technical feasibility of modern commercial large-scale wind turbines and supporting future developments in wind energy and turbine technology.
