Wind energy application in Hungary

Abstract

This paper deals with green wind energy application (depends on solar energy). Nowadays global energy consumption was increased increasingly due to the growing the population and standards of living style. Moreover, with increasing the global warming and environmental pollution, the development of renewable energy sources was becoming more essential. Wind energy is one of the most promising clean and sustainable energy. Wind power plants produce electricity by having rotating three blades. It has three main in its energy chain: wind turbine, gear box and electric generator. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing. If wind flows across the blades, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag forces. The force of the lift is bigger than the drag and this causes the rotor to spin. The rotor connects to the generator, either directly (if it's a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity. The total capacity of wind power capacity is 329 MW in Hungary. Number of operating wind farms are 39, with 172 wind towers. Most of wind farms are in the Kisalföld region in Hungary. Current legislation in Hungary does not allow the installation of new wind power station. My work shows that there is a justification for the use of wind energy in Hungary.
