Design and performance evaluation of vertical axis wind turbine for wind energy harvesting at railway

摘要: This paper aims to design an optimum vertical axis wind turbine (VAWT) and assess its techno-economic performance for energy harvesting at high-speed railway in Malaysia.,This project adopted AutoCAD ANSYS modeling tools optimize the blade of turbine. The site selected has a 30 km with six stops. turbines are placed 1 m apart from each other considering tip speed ratio. power produced net present value had been analyzed evaluate viability.,Computational fluid dynamics (CFD) analysis National Advisory Committee Aeronautics (NACA) 0020 carried out. For 50 m/s swept area 8 m2, generated is 245 kW. eight trains that operate 19 h/day interval 30 min nonpeak hours 15 min peak hours, total 66 MWh/day. average cost saved by train stations RM 16.7 mil/year battery charging capacity 12 h/day.,Wind not commonly used Malaysia due low ranging 1.5 4.5 m/s. Conventional requires minimum cut-in 11 m/s overcome inertia starts generating power. Hence, this proposes VAWT harvest unconventional untapped sources railway. research finding complements alternate technologies which can serve as reference countries experienced similar geographic constraints.
