Among the most important factors that affect the quality of electricity supply and the orderly operation of the power system is maintaining the voltage within the permitted limits. With the integration of extremely variable sources of electricity such as wind farms, the problem of maintaining the voltage within the permitted limits becomes more and more significant. The paper deals with the influence of the connection of the Orlice wind farm on the voltage conditions in the 30 kV distribution network on the stretch Bilice-Primošten-Rogoznica. The paper gives a concise description of the analyzes of voltage conditions in the considered part of the distribution network after the connection of the Orlice wind power plant based on operating measurements and corresponding computer simulations.
