How to design a wind turbine

Renewable-energy sources represent a considerable resource for energy production in the future. The design of a wind farm tender must consider many different factors that must combine with each other to create a project that is sustainable in all respects, coming to get the best compromise between cost and efficiency, not forgetting the environmental impact assessments.

It should first choose a location that is suitable to be used in a valid manner for the installation of a plant for the production of wind energy: according to the characteristics of the territories, must be studied the arrangement and size of the blades, which constitute the heart of a wind farm.

The ideal area is located in a very well ventilated (the assessment will be made by the anemometer measurements), possibly at a higher elevation than the surrounding terrain, and in an area where the installation of the system cannot change the natural balance and landscaping of the site.

For this reason, they are considered to be appropriate for the land in industrial zones. The environmental impact assessment is a major factor for the early stages of design, and for it to be considered valid, it must adapt as much as possible to any facilities in the surrounding area.

Once the appropriate medium, made the necessary preliminary surveys anemometer, it is necessary to perform more in-depth surveys to determine the height and size of the blades, so that you use the most of the wind energy available at that site, without wasting resources and money.

These calculations are also necessary for the calculation of the hours of operation of the plant, which will be in operation 24 hours a day, the calculation used to estimate how much time it takes to develop a certain amount of energy with wind measurement characteristics of the area in question.

Usually, for these calculations, using the Weibull function, adapted to calculate the frequency and distribution, for the values ​​of the function to the relative level or functional year.

The power and efficiency of a generator (blade) depend largely on the wind speed and the time you have been available to make the most of wind energy: to calculate how much energy is produced by a generator, it is sufficient that computes the output power multiplied by the hours that the device was actually active.

If the device is installed in a wind farm with N devices (where N is the total number of generators), its actual production is less than N times that calculated…

As for costs, an element important to assess the actual validity of a project for a project to be considered feasible, the costs for the maintenance and production of energy, must be easily amortized over a short time from the proceeds of the sale of energy produced.
