WEEK 4

Assalamualaikum :)


For this week, I will tell you about the theory of wind turbine generator. This is an explanation what is my project is about theoretically.

So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The most common wind electricity-generating method is using wind turbines. The wind turns large turbine blades, which spins a generator shaft and produces electricity. A wind turbine is connected to a house, battery bank, and/or the state electricity grid. The electricity can then charge batteries, be connected to a building’s mains power, or connected to the national power grid.

The terms wind energy or wind power described as the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

Modern wind turbines are actually a pretty simple concept based on age-old science. The inherent kinetic energy in moving wind spins two, three, or even four propeller blades which are connected to a rotor hub. This rotor spins a central shaft through a gear box, which dramatically increases the rotational speed of the shaft. The shaft then in-turn spins a generator which makes electricity.

The generator makes the electricity through electromagnetic induction, the result of a conductor (coiled wire) moving through a magnetic field (magnets). This electricity can then be stored in batteries for later use or sent out to the power grid. In order for a wind turbine to be effective and efficient, they should be mounted as high as possible and capture wind speeds above 10 miles per hour.
