Efficiency analysis of an installed wind farm

In this study, energy analysis and efficiency study of turbines of a wind farm were performed using data of wind speed, wind direction, air temperature and electric generation, of five selected turbines. Wind energy losses of the plant, monthly and daily performance of turbines were carried out. Parameters influencing the results were also examined in detail. Aerodynamic analysis of turbines was conducted using data of five turbines. Analysis of factors affecting system performance, Betz criteria, power coefficient, energy balance and exergy balance were conducted. Magnitude of wind speeds where turbines start and stop energy generation and influences of these wind speeds on power production and energy losses of five turbines were examined. Consequently, clarifications on the reasons of the losses during conversion of wind power into electric energy, and clarifications on the reasons of instantaneous fluctuations in efficiencies were aimed to be explained. Interactions between aerodynamic parameters during power generation were also reported.
