Electricity generation by using micro wind turbine in metro lines

Due to the increasing human population, the consumption rate of exhaustible resources has also increased. Especially in energy production, methods for the use of renewable energy sources as an alternative to exhaustible sources are becoming more common day by day. The use of wind turbines in electricity generation can be given as an example of this situation. By using wind turbines, it is possible to generate energy with turbines at different locations and with different power capacities. The generation of electrical energy by using micro wind turbines in public transportation vehicles can be given as an example of what has become widespread in city life. The subject of generating electrical energy by the movement of the outside air, which is accelerated by the movement of public transportation vehicles, by using a wind turbine, has been studied by different researchers in recent years. Micro wind turbines are turbines that have many benefits such as do not cost towers, are easy to transport and install due to their size and, can be used almost everywhere in daily life. It has been studied in this thesis to generate energy from the kinetic energy of the air, which is moved by the train movement in the subway stations. Kızılay metro station, which is the most frequent station in Ankara, the capital and second-most crowded city is taken as an example station. The behaviour of the air moving inside, and the velocity profile was obtained by performing flow field analysis in the ANSYS Fluent package program by using the real station dimensions and the gauge dimensions of the wagons. According to the btained velocity data, a suitable micro wind turbine was selected and the daily, weekly, monthly and, annual electrical energy amount that could be obtained with this turbine system was calculated. The results were compared with similar studies in the literature, and it was seen that the amount of electricity produced varies depending on the selected turbine, train speed, and the speed of the air moving accordingly, the number of turbines.
