Efficiency of Modern Wind Turbines in Real Conditions

Abstract

One of the problems of wind energy is determined insufficient information available about the effectiveness of wind farms in the real life conditions, due in particular to commercial issues of use. On the one hand it is associated with the wind loads in effective areas, on the other-lasting licensed wind parameters measurement with difficult access conditions. The paper estimates the economic efficiency of wind farm generators of different capacities. It is shown that in this way we can calculate the wind power parameters necessary for the preliminary analysis of the economic efficiency of-annual electricity production, profitability and return on investment. As a result, the estimation of costs for wind turbines and their installation and operation, profit margins and payback period were estimated. The high efficiency of wind power in terms of the Carpathian region of Ukraine provided detailed characteristics of wind turbine choice for real parameters of wind loads has been shown.
