Geothermal energy, solar energy, wind energy. Future plans and development in this field. Short introduction of these potentials in Serbia.
Wind energy is the kinetic energy possessed by the air flowing. The amount of energy depends mainly on wind speed, but also to a lesser extent, dependent on the density vazuha, which is influenced by temperature and air pressure and altitude. For wind power, the power output of energy dramatically increases with increasing wind speed. Therefore, the most rewarding of wind turbines located in windy areas. At a wind speed affects terrain which is why wind turbines erected on tall towers.
Wind turbines typically produce 40% of the rated power, but under optimal winds, this percentage may rise to 60%.
Wind turbine is a machine for converting the kinetic energy of wind into mechanical energy. If the mechanical energy is used directly in machines such as pumps or machines for grinding grain, it is the wind mills. If the mechanical energy is converted into electricity, it is wind power.
Wind turbines can be divided into two types, based on the position of the axis about which the turbine rotates. The most commonly used horizontal turbines. Today, the most prevalent wind turbines with propellers of three wings, power from 1 kW to 6 MW. In these wind generators are portable system - gearbox and an electric generator at the top of the tower carrier. The whole structure is, with a wind direction sensor and actuator, powered by a propeller always faces perpendicular to the direction of the wind. The most complex part of the gearbox that converts light and uneven movement of the blade to flips constant frequency generator.
Due to the ongoing energy crisis in Serbia, wind energy is proving to be an ideal new capacity, it has a very short period of capital construction, seasonal peak production coincides with the seasonal peak demand and electricity is produced with minimal harm to the environment. In the mid eighties, there were a number of research projects in the field of new and renewable energy sources. Among them, the wind energy. In September 1987, at the Conference on the production of electricity in the energy development strategy, more attention was devoted to alternative sources. It is well known that in our country, potentially sites for wind energy development mountain ranges of eastern Serbia, Vojvodina, mountain plateau in central Serbia and the valley of the Danube, Sava and Morava. Currently out systematic measurements vetroenergetskih potential in several locations in Vojvodina, the right bank of the Sava and Danube rivers, and most has been the measurement of Vlasini. At selected locations, more than one year shall be a systematic examination and investigation of the possibility of accumulation of electricity through hydro electric power plant.
Popularity of wind energy is growing incredibly fast. It is the energy that has just begun to discover their potential. Many countries are investing significant financial resources in research on technologies that could improve the utilization of wind energy. With the increasing popularity of wind energy, reduce the cost of electricity generation in wind turbines. In this way, wind energy is becoming more competitive to traditional fossil fuels.
Study and research in the South Banat shown that the potential of wind energy large and Serbia has a good chance to include its use in order ecologically desirable countries.
