Electrical Power System

Nowadays, the type of energy that most influences the economic expansion by any nation, is electricity. One reason is that this energy offers a number of possibilities to be obtained; as river currents, oil, gas, uranium, coal, the force of the seas and winds, geyser, etc. Furthermore, also is the kind of energy easier to transport from remote sites to the consumption centers, to perform this transport is necessary a system well -structured to allow us to transport energy at low cost and with the fewest possible losses. To achieve these objectives the electric power systems are composed of other subsystems such as: the generation system, the transmission system and the distribution system.

In short words, the porpoise of the generation system is nothing more than transform the mechanical energy produced by any of the phenomena mentioned in the previous paragraph and transforms this energy into electrical energy. This is accomplished by mechanical energy that moves a turbine which is coupled to the shaft of a generator. This generator is where the transformation of mechanical energy to electrical energy by generating a sinusoidal wave with an amplitude between 6000 and 23000 volts. This process is extremely important, because from this sine wave can now be done the rest of the processes of the electric power system.

After the transformation of energy mechanical to electric energy is made, it must find a way to transmit this energy to a place near the consumption centers (usually consumption centers are far from the generation plants). To reduce energy loss in transmission this is done at high levels of voltage, higher voltages to 66000 volts, these transmission systems are supported on large mechanical towers and also are constructed so entangled to transmit energy in either direction. The importance of this process is that anything we would serve the transformation of mechanical energy into electricity, if we can not transport the places where we can use.

After transporting electrical energy, we should lower the voltage levels to distribute electrical energy to the final users, this is done in electrical substations, and these electrical substations are much closer to consumption centers and can reduce voltage to valuesbetween 6000 and 23000 volts. Distribution networks are supported on poles and are usually constructed with a radial distribution. This is the process that allows the electrical energy reaches each of our homes so that we can use to give you deem appropriate.

Although we do not realize, the electrical power system is essential to our current way of life, as almost all the devices we use to carry out our daily activities depend entirely on the supply of electricity. That's why this is so important today and it requires to be studied more thoroughly to ensure increased reliability and performance as this would translate into a reduction in the cost of electric
