Maintenance is an indispensable part of any technical system because the performance of the entire plant depends on it. Wind farms, like all storage systems, require some kind of maintenance, and with wind farms maintenance can be divided into corrective, preventive and predictive. The way wind turbines work, their specifics include types, wind can be said to be a renewable, easily accessible and rich source of energy, and with the help of wind power it is converted into a useful form of energy called electricity. The first part theoretically shows the history of wind farms and their aggregates. their possibilities and the potential of using wind as an energy source.The second part deals with the principle of operation of wind turbines, lists the parts and explains how different versions of wind turbines are divided.The wind turbine is a rotating machine that converts kinetic energy into mechanical, main ul ogu in energy conversion has an electric generator. Then there are the advantages and disadvantages of a wind farm, the price in the production process which has a difference in decline or increase in repairs and construction. At the very end of the paper, a thesis was stated about the construction of wind farms that have an impact on the environment and the living world that inhabits it.
