Modelling of wind turbine performance measurement

Wind turbines become more and more popular worldwide recently as any other renewable energy sources, therefore evaluation of specific turbine efficiency is a significant scientific and technical scope. Direct comparison of a number of performance measurements in general is not correct because of the versatile nature of a real wind. In permanently varying wind conditions the rotational speed is changing greatly causing the appropriate variety spectrum of generating power. The goal of our research was to study a ways of calculation of wind turbine efficiency and performance characteristics based on parameter information received in real wind conditions. Modeling of wind turbine operation was made using Matlab/Simulink software. Modeling showed the importance of the scope and proved its worthiness. Per our opinion the presented paper will be useful for turbine efficiency analysis and would help in the development of methodology for measurement and comparison of different turbines operating in real wind conditions.
