Abstract:The present work is to design a passive pitch-control mechanism for small horizontal axis wind turbine (HAWT) to generate stable power at high wind speeds. The mechanism uses a disk pulley as an actuator to passively adjust the pitch angle of blades by centrifugal force. For this design, aerodynamic braking is caused by the adjustment of pitch angles at high wind speeds. As a marked advantage, this does not require mechanical brakes that would incur electrical burn-out and structural failure under high speed rotation. This can ensure the survival of blades and generator in sever operation environments. In this paper, the analysis uses blade element momentum theory (BEMT) to develop graphical user interface software to facilitate the performance assessment of the small-scale HAWT using passive pitch control (PPC). For verification, the HAWT system was tested in a full-scale wind tunnel for its aerodynamic performance. At low wind speeds, this system performed the same as usual, yet at high wind speeds, the equipped PPC system can effectively reduce the rotational speed to generate stable power.

Abstract. The total potential of wind energy in Indonesia reaches 144 GW. This wind energy potential is dominated by small wind speeds ranging from 4-6 m / s and about 113 GW. This is the reason why the development of small-scale wind powerplant is more feasible to be developed in Indonesia. The characteristics of local wind and geographical conditions of Indonesia which is an archipelagic country are fundamental in designing wind power and utilizing of local materials. This study aims to get local fast-growing wood of wind turbines blades in Indonesia, which has the best physical and mechanical properties of wood, and is tested computationally on certain airfoils and shows a uniform distribution of stress. The types of wood are tested in this study were Sengon (Albizia chinensis), Jabon (Antocephalus cadamba), and Balsa (Ochroma Rowlee grandiflorum). The test covers the basic properties of the wood, physical and mechanical properties. The test results showed that Jabon have density 0.34 was the best compared to Sengon (0.24) and balsa (0.18). The best dimensional stability (T/R Ratios) are Jabon (1.97), sengon (2.19) and balsa (2.84), respectively. With the highest density result and the lowest dimensional stability value, mechanical testing of Jabon wood shows the best mechanical properties. The simulation result using Q-Blade software was obtained airfoil NACA 4415 most suitable for local wind characteristics, and got the low value of stress and distribution color uniformly on each wood.

The aim of this work is to find out the optimum twist angle of small wind turbine blade so as to increase its Annual Energy Production (AEP) by the means of increasing lift force on the blade of turbine in static flow condition. A horizontal-axis wind turbine (HAWT) blade is selected for optimization using an estimate code based on the Blade Element Momentum (BEM) theory. AirfoilsSG6043, BW3 and A18 are selected and utilized as candidates for designing of the micro blades. Blade element momentum theory is used to design the blade 3D geometry in the referred literature. The efficient performance of a wind turbine largely depends on the wind characteristics of the site in conjunction with the aerodynamic shape of the blades. The blade geometry will determine the torque overcome and the power generated by the rotor. By aerodynamic point of view, an economic and efficient blade design is attained by the maximization of rotor power coefficient. Some factors are different for small wind turbine blade design, than large blade. Such as, the small blades experience much lower Reynolds number flow than the large blades, hence large wind turbine airfoils may perform very poorly in small applications. The small turbines can be self-started at wind speeds which are lower, therefore the hub and tip parts are critical for the starting torque which should be able to overcome the resistance of the generator and the mechanical system. Furthermore, a well-designed wind turbine with a low cost of energy will always have an aerodynamically efficient blade. Therefore, the blade design is an important part in the whole design procedure of a wind turbine. In the current study, the objective function is restricted to the cost from the blade which is done by selecting the micro wind turbine profile, performing CFD analysis on the profile with different twist angles and analyzing the results of Lift force for the same. It is observed in CFD results of the blade that 25 degree shows most promising results in the field of lift force.
