WIND TURBINES DESIGN CORRECTIONS FOR NEXT GALICIA CLIMATIC CONDITIONS

Planet Global Heating was analysed in recent studies for Galician climate showing a rise in the average temperature in each season and a slight decrement in summer wind frequency. In consequence, the effect of the climate change can involve an error in wind turbine selection andits behaviour once it was put in. Furthermore, being the technical lifetime for a turbine twenty years onshore and twenty-five years offshore it is theright time to consider new development pathways such as lower moist air density and low speed wind turbines. In this paper twenty-four wind turbines were analysed in a typical year to get a model that relates weather to power conversion. Once done that, theeffect of the climate change was evaluated in Galician wind farms showing a 10% fall during spring and summer season. Therefore, future works about new technologies that workout well under those conditions like low wind turbines must be done.
