Online Tutoring on Wind Power

Energy production through wind is a widely used method yet it is a crucial one containing several steps. Generating electricity from wind is an alternative source of energy that is used by many countries around the world. The main idea of the process is to produce power by using wind turbines by which the kinetic energy of wind is turned into electrical energy to be used at homes and businesses.

At the beginning of the process, the wind blows on the blades of the wind turbines rotors which causes them to spin. The spinning of the rotors allows the kinetic energy to be converted into mechanical energy. After the mechanical energy is produced, the sensors in the wind turbines detect the strength and velocity of the wind as well as its direction. The rotors then are turned to face the wind for protecting the potential damage to the turbine (Culture Change, 2005).

 

The shafts and gearbox are then connected to the rotor and generator to allow the generator to move along with rotor. Meanwhile spinning, the generator uses the electromagnetic field to convert the mechanical energy into electrical energy. This electrical energy is then transmitted to the substations with the help of long thick copper cables (Dodge, 2010). At this stage, the electrical energy that is being generated by the turbines is combined with the high voltage to produce better results.

The national grid then uses the high voltage power for transmitting the electricity more efficiently at homes and businesses where the transformers help in reducing the voltage back at lower level for usage (Ackermann, 2005).
