Abstract—Wind energy is one of the highest efficiency in
renewable energy. Unfortunately, wind energy was not
developed much in Thailand because the average wind speed of
the city area is limited to the medium-low range which makes
wind energy unsuitable for power generation. Recently, there
are the researches tried to apply the wind turbine to wind
source besides the bus. According to a large amount of vehicles
transport from upcountry into the city 5n Thailand, wind
energy can be considered as the potential energy only if the
turbine can operate the high efficiency. With this reason, the
object of this project focuses on the efficiency factors of a wind
turbine to be able to use in low-speed wind energy especially
wind that source by the passenger car includes designing and
developing wind turbine for propeller’s efficiency increasing.
This project used 200-Watt Savonius wind turbine to
experiment with the effect of 1) weight of propeller, 2) material
of propeller, and 3) swept area of the propeller to the efficiency
of the wind turbine. The research and experiment yield the
results that all factors are affecting to RPM, electric power and
efficiency of Savonius wind turbine. This project can increase
the efficiency of small wind turbine about 26% for use in
low-speed wind sources.
Index Terms—Renewable energy, wind turbine, efficiency,
