Generator Power Station System

Generation is the part of power system where we convert some form of energy into electrical energy. This is the source of energy in the power system. It keeps running all the time. It generates power at different voltage and power levels depending upon the type of station and the generators used.

In almost all cases, generators will have higher energy generation capabilities than portable power stations. Portable power stations store energy in a battery, while generators use mechanical energy to create electricity. Generators can supply power to devices and larger appliances. They have an average output of 4,000 to 12,000 watts per hour.

Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power (these are also known as an alternator). The relative motion between a magnetic field and an electrical conductor creates an electric current.

An electric power system or electric grid is known as a large network of power generating plants which connected to the consumer loads. As, it is well known that “Energy cannot be created nor be destroyed but can only be converted from one form of energy to another form of energy”.

In this system, generators will be connected to a common bus and the auxiliary transformers for all generating units will be fed from that common bus. This bus may have one or more other power sources to serve for station startup. Figure 1 is a typical one-line diagram for such a system.

Power plants are usually located in suburban areas or far from cities due to their need for large amounts of land and water, as well as requirements for waste disposal. For this reason, a power generating station has to not only concern itself with the efficient generation of power, but also in the transmission of this power.
