In the world, the capacities that use wind energy are increasing. Thus, these changes that develop in the framework of wind energy also require the development and accuracy of the forecast of the energy that can be produced. A main reason for this could be the fact that it is required to have stability in the energy network. In the field of wind energy, respectively the feasibility of wind farms, different software have been developed, some enabling 3D simulations and some linear simulations, without affecting the accuracy of the forecast. Various software advance in forecasting and this also increases the reliability of the analyzes carried out. This study analyzes the WAsP software, developed by DTU. This software is used for the purpose of analyzing the energy that can be produced at the output, the losses caused by the wake effect and so on. The place taken in the study is a complex mountainous terrain, in which the measurements were carried out for a year wind parameters at different heights, and the highest height is considered for the analyzes carried out here. The turbines used in the study are of the General Electric 3.6MW and General Electric 3.2MW types. The country being analyzed is in Kosovo, exactly Kitka, on the border with the neighboring state.

W artykule analizowano możliwość wykorzystania oprogramowania WAsP WindSimulations do projektowania usytuowania farm wiatrowych w złożonym ukształtowaniu terenu. Możliwe było uwzględnienie turbulencji wiatru, obecność lasów, budynków etc.
