Uproszczona analiza farmy wiatrowej o założonej mocy znamionowej pod kątem wybranych parametrów technicznych, ekonomicznych i wiatrowych

In this paper, simplyfied analysis of different conditions of wind power expansion in Poland is shown. This analysis is made on basis simplyfied computational example of 18 MW wind farm in Poland from the point of view of different group of parameters. Four groups of conditions: wind, geographical, technical and economical are taken into consideration. Introduction is contained short analysis of wind energy expansion in Poland in last times. First group of conditions is contained wind regime (consistent with mesoscale) as: yearly wind speed and Weibull distribution. Second group of consider conditions is geographical conditions as: localisation of wind farm, surface class, roughness and height. Third group of consider conditions were technical conditions connecting with selected unit of wind turbine for wind farm. Fourth group of consider conditions were economical factors as: wind turbine price, installation cost of turbine, operational & maintenance cost, price per kWh, price of property rigths connecting with certificates of origin, rate of discount etc-. In frames this project two main groups of calculations were realised. First group were year energy output calculations of 18 MW wind farm for applied wind units, wind speeds and surface classes. Second group were calculations of electricity cost per kWh produced electric energy for mentioned earlier factors and for assumed prizes per kWh electric energy sale for distribution company. Results of realised computational calculations are placed in shape of tables. Conclusions contain analysis of impact of inquired conditions for key parameters of wind farm - magnitude of year energy output and electricity cost per kWh produced electric energy, which decide about wind farm effectivity.
