The purpose of this work is to find a simple analytical dependence for the utilization factor of the installed capacity of a wind power plant on the parameters of its power characteristics and the parameters of the wind cadastre at the proposed location of the wind power plant at a given height of the axis of its wind wheel. Based on the study of the power characteristics of 50’s wind power plants of various manufacturers with a capacity of 2.0 MW to 3.6 MW, it has been shown that these characteristics are well described by the Weibull – Gnedenko two-parameter integral distribution. A simple asymptotic expression for the installed power utilization factor depending on two parameters of the Weibull – Gnedenko differential distribution for the wind speed and two parameters of the Weibull – Gnedenko integral distribution for the power characteristic of a wind power plant has been obtained. It has been shown that the predictions of the asymptotic expression differ by no more than 2% from the results of numerical calculations of the installed capacity utilization factor and, therefore, can be used to select or design a specific wind power plant on the proposed area at a given height of the wind wheel axis.
