Electrical Power System: Generation, Transmission and Distribution of Electrical Power

Electrical Power System: Generation, Transmission and Distribution of Electrical Power An electric power system or electric grid is known as a large network of power generating plants which connected to the consumer loads. The lines network between Generating Station (Power Station) and consumer of electric power can be divided into two parts. Transmission System Distribution System The main objective of an electric power system is to obtain electrical energy and make it reachable safely to the load point where it is being used in usable form. This is done in five stages namely Generating Station, Primary Transmission, Secondary Transmission, Primary Distribution, Secondary Distribution The following parts of a typical power supply scheme are shown in figure. After these five levels, the energy must be available as the stated form in terms of voltage magnitudes, frequency and consistency. Generation means the conversion of a form of energy into electrical energy. Transmission implies the transport of this energy to very long distance with very high amount of voltage magnitude. Moreover, distribution is fulfilling the demand of the consumers at certified voltage level and it is done in terms of feeders. Feeders are the small-small chunks of load distributed at different places, physically. Let’s explain all of the above levels one by one.
