Abstract

The need for electrical energy from renewable energy is very high one by developing a type of power plant with wind turbines as a prime mover. Wind turbine is a tool used as a renewable energy power plant. The wind turbine is designed using 3 blades made from PVC with variation of 20o , 25o, and 30o blade angle blades (r = 1 m) generator on wind turbine having maximum power specification 180 Watt with 12 Volt power supply and electric current strength 15 Ampere. Wind turbine testing was tested above with an average wind speed of 7,01 m / s at an angle of 20o , with rotation of blades reaching 244 rpm ; average wind speed 7,10 m/s at 25o angle with rotation reaching 291 rpm ; while the wind speed is 7,06 m/s at an angle of 30o with the highest turn reaching 316 rpm. This is because the slope angle of the blades that received the wind can affect the sweep of the blade. Average wind velocity on output power, where the lowest yield at an angle of 20o with a wind speed of 7,01 m/s generate power 1,03 Watt ; at an angle of 25o with a wind speed of 7,10 m/s generate power of 11,23 Watt ; the highest power at an angle of 30o with a wind speed of 7,06 m/s generates power of 12,71 Watt. The smaller the angle of the slope the smaller the power generated.
