The Savonius wind turbines convert wind energy into electrical energy. Unfortunately,
these turbines have lower performance than other types of turbines. In previous research, addition
disturbance cylinder in front of the returning blade with the addition of 1 fin on the blade has been
proven to increase the performance of the turbine. Although the increase not optimal. Based on above
problems, and experimental study was carried out placing the fins and the interfering cylinder at the
same place and time. This experiment uses a savonius turbine with n=1 myring type fins. Turbine
blade height and diameter of 40 cm. Variation of interfering cylinder distance S/d = 1.4; 1.7; 2.0; and
2,3. The test uses variations in wind speed of 5 m/s; 6m/s; and 7 m/s and carried out 12 times to
determine the effect of adding interfering cylinders and fins at the turbine blades to coefficient of
power (Cp) and the coefficient of torque (Ct). The end result shows that the best performance
improvement the savonius wind turbine occurs in variation the interfering cylinder distance ratio S/d
= 1.4 at a wind speed of 6 m/s. The increase in the coefficient of torque.(Ct) is 15.01% and coefficient
of power (Cp) is 89.95% for turbines without interfering cylinders.......
