To understand how it works, one must first familiarize you with what a wind farm is. When wind turbines are grouped together and set up in the same location to generate more electricity, they form what we now refer to as a wind farm. The wind turbines are connected to each other, with a minimum of a couple of dozen wind turbines to as much as one hundred turbines. A turbine comes in many different sizes. Large ones are meant to generate many units of energy that will benefit thousands of homes and businesses. Small models are available to individuals who are interested in supplying power to their homes on their own.
How a wind turbine works, is much like a fan, only in reverse. Instead of blowing air around, it takes the air streams and converts it into electricity. It is powered by large blades, some as big as two hundred feet in length. The constant turning of the blades supplies raw energy to a generator, which processes the motion of the blade into electrical current. The current flows through power lines, which are connected to homes.
An offshore wind farm is usually highly recommended, as this ensures more wind power as there are more strong winds over ocean surfaces. When wind turbines are assembled offshore, then they are set up on the seabed. The wind turbines will pick up wind direction through its sensors. And then, the wind turbine head will absorb the maximum amount of wind energy. This energy will be passed on to a generator that is connected to the turbine. The energy will be converted into electricity by a generator, and the same generator will send it to the grid.
The first key step in how it works is that piles are installed into the seabed once you have decided on an optimum location for your wind farm. At the base of the piles, erosion protection is installed so that there will be no damage to the sea floor. The topmost part of the wind turbines is colored with bright use so that nearby and arriving ships can see them and avoid accidents. Once the group of wind turbines has been installed on the seabed, the sensors turn the nacelle – which is the head of the turbine – towards the wind direction they have detected. The blades must face the wind so that they can collect as much wind energy. How the wind moves over the blades directs the blade rotation over the hub which is connected to the shaft of the nacelle. A gearbox is installed inside this shaft, and this powers the generator for energy-conversion purposes. There are cables found in the sub-sea which brings the power from the generator to the offshore transformer. After that, the wind power is converted to electricity in high voltage. This process answers the question of how it works
Although people are concerned with the appearance of wind farms, the aesthetic appeal of these constructions could well be overlooked in the interest of considering the power these wind farms generate. Because of the noise created by the movement of the blades as well as the generators, sometimes, making sure that the wind farm is located in areas that will not disrupt peace is highly recommended. The environmental benefits of wind farms, as always, cannot be overemphasized.
