A New Model of Wind Turbine

Abstract

The paper presents a summary of many years of tests carried out by the authors searching for the most efficient and, at the same time, the most economical project of a wind generator. This paper presents the results of the tests of several scale models in a wind tunnel. The paper shows a general scheme of a wind generator equipped with two air turbines located at the ends of the nacelle. The design of the wind turbine and its blades as main elements are described. The results of a comparative test of the generator model equipped with one and two turbines mounted on the same shaft and the dependence of the generator efficiency on the parameters of the blades are also presented. A new multiplier scheme for the speed of the electric generator shaft and a method to control the energy of the wind generator in a wide range of speed is included. The material is intended to be used by engineers working in the energy industry dedicated to the design and manufacture of medium and high power wind turbines.
