Thermodynamic analysis of wind power installations efficiency
Abstract
According to thermodynamic law of impacts and consequences thereof subsonic wind flow passing through wind wheel section speeds up and becomes increasingly turbulent flow along the length of currents. It is shown that the existing theory of ideal wind engine, based on the assumption that technical work is done by wind power installation at the expense of the decrease of kinetic energy of wind flow, does not correspond to reality. The example of calculation of output speed of V112-3,3MWTM/ECIB wind power generator of “Vestas” company is presented in the article.
