Output of wind turbines to the number of available energy resources, especially in the absence of wind the weather? This problem has plagued engineers and influence the decisions of potential users. Iran University of Science Mechanical Engineering AbolfazlAhmadi and MehdiAliEhyaei wind power has “energy” to the survey. Their research has been published in the recent publication InternationalJournalofExergy. Available energy is the energy in the thermodynamics to evaluate the quality parameters.
Wind is the oldest one of the resources of renewable energy. Rotating fan blades to capture wind energy and convert it into useful energy. Modern wind turbines to produce electricity to use this concept to drive the rest of the equipment. Wind turbines of different sizes, from small residential application a few kilowatts to more than 5MW of industrial-scale power generation.
Ahmadi and Ehyaei pointed out that the wind turbine have to compete with many other energy sources, primarily fossil fuels, as well as other renewable energy sources such as solar and biomass technologies. Therefore, the wind turbine to be cost-effective to comply with environmental benefits.
Wind turbines must be designed to meet the load requirements, and energy output at the lowest cost. In order to address this cost problem, we must optimize the performance characteristics, such as output power and wind speed or with the rotor angular velocity. Useful to analyze is to look at the system output of energy, “quality.” The researchers believe that Under normal circumstances, more than 9 meters per second wind speed was considered useful to be able to calculate the wind turbine does not matter, the initial study did not carry out historical analysis will be required for all the factors taken into account.
They have now developed a set of wind turbines to improve energy analysis, the wind kinetic energy to consider greater detail. Their approach is to provide a wind turbine run-time model of how the loss of potential energy. Then, put forward an optimized wind generator are three main parameters (intercept and and Orio rated wind speed) method so that at any given wind speed (from breeze to strong wind), the safe operation of the wind turbine within the parameters of maximize the use of energy.
They have a different wind speed in Iran, Tehran and Manjil two cities have embarked on a wind turbine generator energy analysis. Tehran average wind speed is low, while the Manjil is a windy city. Their formula can provide the optimal value of the wind turbine speed (change depending on wind speed). The results showed that the theoretical efficiency of the two regions increased by 20%, “waste” out of energy reduction of 80%.
