Vertical axis turbines of wind power plants

This paper deals with the use of renewable energy sources with a focus on electricity generation using vertical axis wind turbines. The installed capacity of wind power plants increases with the gradual decreasing of fossil fuels reserves. Nowadays, the horizontal axis turbines are the most widely used. This paper describes the design of function models of wind turbines with a vertical axis. Characteristics of wind turbine models were verified by laboratory measurements. The results show that the rotor design has a significant impact on its parameters. The best results were achieved by the multi-stage rotors.
