TRANSMISSION SYSTEM IN SMALL WIND TURBINE

Growing energy demand and public awareness on the environmental impact of
non-renewable energy source has increase public interest in renewable energy especially
wind energy. Nowadays countries like India, Germany, France, Spain, UK, USA and
many more are widely using wind energy as an alternative source of power generation
[I]. However, in Malaysia, wind energy is not very popular because the wind condition
is variable due to the seasonal variation. The maximum wind speed in Malaysia is
around 4-5 m/s annually [2]. With the right design of wind turbine, this wind speed is
enough to generate power for household in order to reduce the dependency on the
conventional power generation. This report is about the design and analysis of
transmission system in small wind turbine. The first step is to design the transmission
system for small wind turbine. With the right gear ratio, it can increase from low speed
shaft into high speed shaft so that it is sufficient for generator to generate electricity. The
designed transmission system is then translated into 3D drawing using CATIA V5Rl8
software to create a model for simulation later. ANSYS Workbench simulation software
is used to simulate the static structural analysis of the transmission system to determine
the equivalent (von-mises) stress, maximum shear stress, total deformation and safety
factor. The results gained from the analysis are gathered and analyze to conclude the
condition of the transmission system designed. Lastly, some recommendations are
included for further study in the future.
