Residences, buildings and commercial sites needs more power, but also continuous power. Important facilities such as wireless or radio sets requires small amount of energy, but with a continuous supply. This project was done to design and construct a vertical axis wind turbine for small scale use. After an introduction about the historical background of wind turbine, the report deals with a more accurate analysis of the main type of vertical axis wind turbine, showing their characteristics, advantages and disadvantages, differences between vertical axis wind turbine and horizontal axis wind turbine and their operations. The parameter of the wind turbines was discussed and the generators stator that can be used to connect the wind mill to the electricity grid are reported as well. Several statistics are also presented, in order to explain how the development of the wind energy in Nigeria. Results from trials shows that as the speed increases, there is increase in voltage and this in turn implies a watt change at different speeds. This also implies that when there is high wind, there is a higher rpm. Keywords: Turbine, wind, electricity, power, energy, fossil fuel and natural gas.

In addition, solid shaft will be machined to create steps as so that the bearings will be fitted easily to the ends. This study was done to investigate the In this research, it was revealed that using a counter rotating design and development of the vertical axis micro wind wind turbine with a freely rotating generator can produce turbines.

The contribution of counter rotating impellers with a higher amounts of power than common wind generators. Even freely rotating generator to produce energy was investigated.

Possible developments were considered.

It was imagined that the task has been completed and all the targets were reached. It must have a frame to hold the bearings and rotating ability would be only two times less than if we had two identical counter rotating blade components such as single ones.

Therefore the power output could be estimated Savonius or Darrieus blade types, etc. Then, the torque should be gathered through a generator whose stator 5. As the two separate shafts are connected to the In small scale residential or rural applications, the use of small generator, the power has to be transmitted by a slip ring to a wind turbines for the production of electricity is a common battery tank, the grid or the experimental measurement devices. The use of permanent magnets in a coreless functional conditions and design considerations.

All these axial flux generator makes the construction process easier and points are examined during the complete concept design suitable for locally manufactured open hardware wind power process. The generator used for the project was the Printed DC applications. Using these lay down designs as a basic platform, motors which are a kind of improved axial flux permanent along with some simple theoretical equations, the generator can magnet AFPM machines.

Printed DC motors have needed, in any small scale application. In this chapter, a very thin structure because the wires are placed on a thin disk description of these basic theoretical concepts and construction and the magnets are relatively small, the rotation of the motor methods is presented. The magnetic disks when coupled with the stator forms 2 Hub Galvanized steel the generator.

The frame of the blade was made The performance of the machine was satisfactory during the from flat bar and square rod. Each blade consists of three preliminary tests.

Voltage was generated accordingly. The square rod of height mm each and three flat bar of mm.

The turbine is made up was welded to the square rod. Figure 5 8. This creates an electrical field that is made into Alternating current AC.

The AC current can be converted to direct current DC using uncontrolled diode rectifier with a voltage regulator to stabilize the voltage from the wind turbine.

AC is the type of current a typical household outlet uses. Then, the AC current runs to either your home or a power plant for distribution across several neighborhoods. Stop watch 2. Multi meter 3.

The turbine is mainly for small scale use, operation and maintenance. The turbine capacity is adequate for its purpose and has been proven to be efficient in generation of current.

Wind power

S and Muljadi E. B , the history and running it with an electric motor and the rpm was taken and the state of the art of variable-speed wind turbine technology. This also implies that when there is high wind, there is [2] Darrieus G. S, and Fartaj A. Engineering , Pp- Renewable and Sustainable Energy Reviews p. Pp- Ideally, one would combine the effect of reduced wind speeds with the realism of observed wind fields and thereby obtain better estimates of wind power limits of different regions.

Here, we present such an approach, test it against climate model simulations for different regions across land and ocean, and evaluate the implications of atmospheric effects on the electricity generation rate of individual wind turbines. Our approach uses the atmospheric momentum balance as the physical basis to predict how wind speeds decline in the presence of wind turbines.

This approach therefore includes the effect that more wind turbines lower wind speeds, yielding the limit or maximum rate of kinetic energy that can theoretically be extracted from the atmosphere by the turbines. This approach [vertical kinetic energy VKE 6 , 7 , 13 ] thus estimates the large-scale limit of wind power generation within a region. The goal here is to evaluate the broader geographic applicability of the VKE approach over a range of climatic conditions by comparing VKE estimates to those simulated by a general circulation model GCM with various intensities of wind power deployment.

Not only do the wind power limits predicted by mVKE and the GCM approach match within a factor of 2, but they also agree well with previously published estimates using other GCMs 6 , 8 , 11 , These mVKE estimates are substantially lower than estimates based only on observed wind speed and technical characteristics of the turbines 3 — 5 , The reduction in wind speeds plays a central role in shaping these lower estimates: it directly impacts the electricity generation rate of each turbine, regardless of its technical design.

We then discuss that including these atmospheric effects is critical to planning for the expansion of large-scale wind power. The effect of wind turbines is described by an additional drag component in the surface momentum flux in the model. This added drag in combination with the simulated wind speeds is then used to estimate the rate of electricity generation by the wind turbines.

Note that this expression only uses the natural conditions of the control climate and no technical specifications.

We refer to this modified estimate as the mVKE estimate. More details on the methodology are provided in SI Appendix.

Results and Discussion We first identify the wind power limits within the GCM sensitivity simulations and the associated changes in wind speeds Fig. As would be expected, electricity generation first increases with greater installed capacity but then reaches a maximum rate of about 0.
