The utilization of moving train as an alternative energy sources in railways with savonius wind turbine

Abstract

The purpose of this research is to obtain the dimensions of the savonius wind turbine and to test the calculation results and design of the savonius wind turbine based on the wind speed generated due to the movement of the train in the tunnel. The method used is to calculate the dimensions of the turbine diameter. The results of the calculations show that the savonius wind turbine diameter is 60 cm with a height of 60 cm. The maximum voltage generated is 12.26 V with a current of 0.52 A at a wind speed of 5.7 m/s.
