Abstract:
Wind energy as one of renewable energy resource has a great
potential to solve the problem of dependency on fossil fuels,
especially in Pekanbaru, Indonesia. Pekanbaru wind speed
condition which is considered relatively low can be harnessed
efficiently by designing blades which suits wind condition in
Pekanbaru. Blades are designed using aerodynamic equations and
software assistance such as Microsoft Excel, Qblade, and
Autodesk Inventor. As a result, the blades can generate
mechanical power at low wind speeds with a radius 1.1 m and
hub 0.2 m and the chord length at the base of the blade 0.13 m
and at the tip 0.26 with twist angle at the base of the blade 20.4
and at the tip 5.6 . The result of this research is to show that the
inverse taper blade design is applicable in low wind speed
conditions in order to produce an affordable, compact, and
efficient wind turbine appropriate for wind characteristic in
Pekanbaru.
