A wind turbine is a simple machine that harnesses the power of the wind and converts it to kinetic energy. It can either use it to kinetic energy or turn it into electric energy. A windmill is an example of wind turbine. It does its job by directly applying mechanical energy into machines and pumps. Wind generators use kinetic energy to generate electricity. Here we will know the basics of how to build a wind turbine.
Choosing The Raw Material
The first step is to choose the most suitable raw materials to use for the construction of the turbine. Make sure that your chosen material can handle decay, deterioration, and rust on a permanent basis. Rotor blades are usually made from glass reinforced plastic with epoxy resin matrix. At times, it is constructed from aluminum materials but GRP is the most suitable material.
During the primitive period, canvas and wood were used as materials for rotor blades but they lacked the needed aerodynamics.
The Axis and Aerodynamics
There are two types of axis in a wind turbine namely the horizontal and vertical axis. The most commonly used is the horizontal axis turbine.
The Height of the Tower
When learning how to build a turbine, you will realize that towers are built on areas of high altitude because of the fact that they require less drag and lesser resistance aside from having a lower density of polluting particles. Usually the height of the tower is twice or thrice the length of the rotor blades resulting to higher stability and strength.
The number of blades are dependent on the nature and amount of work, efficiency, handling, budget, reliability, and aesthetics.
Control and Braking
The ratio of the flowing wind and speed of the rotor blades is called speed factor. For optimized efficiency, you need to control the speed and torque of the rotation by maintaining the proper speed limit of the genset, balance centripetal forces, and avoiding exceeding the strength limit. This will result to long-term maintenance and reduced noise.
An understanding of how to build a turbine will tell you that control is very important because of the indispensable factors that can come into play. Control methods should be properly implemented. Furling can be used to optimize the speed of the wind turbine while dumping can be used to implement braking.
By implementing these methods, you can easily construct the wind at the right locations. One should not only consider placing wind turbines in multiple numbers but also consider their positioning and relative directions. By taking these factors into consideration, you will be able to properly implement the steps on how to build a wind turbine.
