A horizontal axis wind turbine design research has been carried out using an inverter. This study aims to generate the output power generated by the generator through an inverter. So that the use of an inverter can turn on the 10 watt lamp. From the research results obtained turbine rotation varied between 1357 rpm to 2415 rpm producing a generator voltage of 3.05 volts to 4.61 volts and generator currents 32mA up to 49 mA. The inverter produces a voltage of 16.57 volts up to 20.46 volts and an inverter current of 0.60 amperes up to 0.48 amperes. The greater the rotation of the wind turbine turbine, the greater the generator voltage generated and so is the voltage of the inverter. While the current will increase as the turbine rotation increases and the inverse of the inverter current will decrease as the turbine rotation increases.

Unsteady Conditions

An efficient and reliable exploitation of small horizontal-axis wind turbines (HAWT) is a complex task: these kinds of devices actually modulate strongly variable loads with rotational speeds of the order of hundreds of revolutions per minute. The complex flow conditions to which small HAWTs are subjected in urban environments (sudden wind direction changes, considerable turbulence intensity, gusts) make it very difficult for the wind turbine control system to optimally balance the power and the load. For these reasons, it is important to comprehend and characterize the behavior of small HAWTs under unsteady conditions. On these grounds, this work is devoted to the formulation and realization of controlled unsteady test conditions for small HAWTs in the wind tunnel. The selected test case is a HAWT having 3 kW of maximum power and 2 m of rotor diameter: in this work, this device is subjected to oscillating wind time series, with a custom period. The experimental analysis allows therefore to characterize how unsteadiness is amplified moving from the primary resource (the wind) through the rotor revolutions per minute to final output (the power), in terms of delay and amplitude magnification. This work also includes a numerical characterization of the problem, by means of aeroelastic simulations performed with the FAST software. The comparison between experiments and numerical model supports the fact that the fast transitions are mainly governed by the aerodynamic and mechanical parameters: therefore, the aeroelastic modeling of a small HAWT can be useful in the developing phase to select appropriately the design and the control system set up.

The Relationship

This paper describes the experimental results of output power augmentation of a horizontal axis wind turbine with a tip vane. In order to find the relationship between the performance of the turbine and the configuration of the tip vane, various types and sizes were used. It was found that V-type and S-type tip vanes can improve turbine performance. Also, the dimensions of V- and S-type tip vanes were investigated. The maximum improvement achieved was a 25 percent increase in power in an existing wind turbine without a tip vane.

Horizontal Axis Wind Turbine

This study is aimed to optimize the conversion of kinetic wind energy into electrical energy. Wind energy is a sustainable energy that is preferred to generate electricity for its low generation cost and low CO2 emissions. The considerations of physical principles of a horizontal axis wind turbine were involved in the study. Controlling of the blade angle deviation and the turbine rotation direction was also considered. For this purpose, a complete wind turbine system was setup by using the computerized simulation software (PSCAD). The system was running at five different cases with different wind speeds and different angles of the blade. The system was successfully generating a maximum output power from the wind turbine based on the changing of the deflection angle of the blade. Also the system would shut down if there were no matching between the wind speed and its direction with the angle of the blade.

Electrical Output

Some area in Indonesia such as southern part of Sumatra to Nusa Tenggara have big enough wind speed to produce electrical energy by using wind turbine. However, the potential resources are not yet fully developed, and only 1.4 GW electrical energy has been generating in the Indonesia region. Most of the wind energy generating equipment is designed to the European wind speed which is   10 - 30 knot. So, it is very important to modify the such equipment to be able to implement in Indonesia area which is have a lower wind speed.The purpose of this research is to know the influence of number of blades and wind speed to electricity generated by horizontal axis wind turbine with blade taper inversed linear.The result showed that the highest electrical output power was 2,02 watt produced by 5 blades and 3,5 m/s wind speed. The lowest electrical output power was 2,347 watt achieved by using 3 blades and 2,5 m/s wind speed.

The aerodynamical design of backward swept for a horizontal axis wind turbine blade has been carried out to produce more power at higher wind velocities. The backward sweep is added by tilting the blade toward the air flow direction. Computational Fluid Dynamics (CFD) calculations were used for solving the conservation equations in one outer stationary reference frame and one inner rotating reference frame, where the blades and grids were fixed in reference to the rotating frame. The blade structure was validated using Reynolds Averaged Navier-Stokes (RANS) solver in a test case by the National Renewable Energy Laboratory (NREL) VI blades results. Simulation results show considerable agreement with the NREL measurements. Standard K-ε turbulence model was chosen for simulations and for the backward swept design process. A sample backward sweep design was applied to the blades of a Horizontal Axis Wind Turbine (HAWT) rotor, and it is obtained that although at the lower wind velocities the output power and the axial thrust of the rotor decrease, at the higher wind velocities the output power increases while the axial thrust decreases. The swept blades have shown about 30 percent increase in output power and about 12 percent decrease in thrust at the wind speed of 14 m/s.Article History: Received June 23rd 2018; Received in revised form Sept 16th 2018; Accepted October 1st 2018; Available onlineHow to Cite This Article: Salari, M.S., Boushehri, B.Z. and Boroushaki, M.

Breaking Effect

This paper describes the development of a passive system to control the output power of a horizontal axis wind turbine. This pitch-flap coupling mechanism can reduce rotor power above rated wind speed. This mechanism has two kinds of blade motions: the flapping and the pitching motions. In this paper, braking effects are investigated experimentally. It is found that the breaking effect is improved when the ratio of pitch to flap motions is large. Also, the flow pattern around the wind turbine is investigated. It is found that the braking effects are caused by a couple of ring vortices.
