Abstract

Design & Operational Analysis of Three Bladed Horizontal Axis Wind Turbine with a Capacity of 750 Watt in Sialanguan Village. This design is about the HWAT design with the aim of determining the design of 3 bladed HWAT to produce 750 Watt power, determining the influence of wind speed on turbine power, the influence of pitch on turbine power and the influence of yawing on turbine power. This design uses quantitative methods to sort data with the help of Microsoft Excel, Qblade, Rstudio and Origin software. This design uses wind speeds of 3 m/s. 12 tests were carried out with different variable variations. The test results show the maximum power produced by the turbine is 19.74 kW with variable values of wind speed 8.68 m / s, pitching 0o and yawing 0o. The three-blade 750 Watt HWAT design in Sialanguan Village has a radius of 5.457639 m with NACA 4412 airfoil. The effect of wind speed on turbine power is significant. An increase in the value of wind speed will result in an increase in the value of lift force on the turbine blades so that the turbine power is greater. The effect of pitching on turbine power is significant. The greater the pitching value, the smaller the turbine power value. The effect of yawing on turbine power is significant. The greater the yawing value, the smaller the turbine power value will be, the addition of the yawing value will reduce the turbine sweep area.
