Abstract :
The wind power plant is a new renewable energy (EBT) power plant that uses wind turbines to convert wind energy to electrical energy. One of the modifications made to wind turbines is to vary the number of blades. The results of the variation in the number of blades are expected to increase the efficiency and location requirements to be installed based on the wind speed obtained. In this study, variations in the number of blades 2, 3, 5 and 8 will be carried out assisted by the Q-Blade application to determine the calculation results along with graphs. Variations were also carried out at wind speeds of 1.9 m / s, 2.9 m / s and 4.8 m / s. With the power plan generated 400 watts with a horizontal axis wind turbine. With an average wind speed of 2.9 m / s, there is a variation of the number of 2 power blades of 44.007 watts with a rotation speed of 129.234 rpm with a Cp of 0.416763, blade 3 of 50.9077 watts of power with a rotation speed of 92.3101 rpm with Cp 0 , 482115, the variation of the number of 5 power blades is 52.0975 watts with a rotation speed of 73.8481 rpm with a Cp of 0.493383, the variation of the number of 8 power blades is 55.4924 watts with a rotation speed of 55.3861 rpm with a Cp 0.525534
