Maximum Power of Horizontal and Vertical Wind Turbine to Changes on Wind Speed and Number of Blade

This paper discusses the comparative study of horizontal and vertical wind turbines. The optimum power output is to be produced by the two types of turbine. While the input parameters are changes in wind speed and number of blades. Therefore the comparison is fair, the same area of wind sweeping is used for both turbines. The area of wind sweeping means that the surface area of the two turbines is the same. The simulation would use numerical computing with input wind speeds and the number of turbines that change in time. To get optimum power needs to be sought first-speed tip ratio. The parameter is the ratio between the wind speed and turbine rotation speed. The tip speed ratio would be used to obtain the coefficient parameters of the turbine (Cp). The turbine coefficient value greatly affects the power that can be generated by wind turbines. Every time there is a change in wind and changes in the number of blades, the value of the speed tip ratio and turbine coefficientwould also change. The relationship of changes in these parameters is non-linear, which means that if the wind speed and the number of blades increases, it is uncertain the speed tip ratio and turbine's coefficientwould also increase. So is the relationship with changes in turbine power, if the wind speed and turbine rotation speed increase, it is uncertain the power produced by the turbine would also increase. The results of this comparison, for simulations with number of blades 2, on VAWT the maximum power that can be generated is 579,03 W, and the maximum power of HAWT is 900,58 W. For simulations with number of blades 3, the VAWT maximum power that can be produced is 789,59 W, and the maximum power of HAWT is 1.109,27 W. For simulations with number of blades 4, on VAWT the maximum power that can be produced is 947.5 W, and the maximum power of HAWT is 824,84 W.
