In this paper considered the engineering analysis of a diffuser with a closed-type wind power plant by converting the kinetic energy of the oncoming wind into electrical energy. The study of the wind turbine diffuser was carried out in order to increase the energy efficiency of converting wind energy into electrical energy. The closed-type wind turbine design is converted into a finite element model for aerodynamic calculations. The model of a closed-type wind turbine is investigated by changing the angle of attack of the diffuser, with various options for its parameters in order to find the most optimal conditions for increasing the energy efficiency factor of the energy carrier, which will ensure high energy efficiency of converting wind energy into electrical energy. Based on the study results was recommended the diffuser with the optimal angle of attack by constructing a closed-type wind turbine.
