A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In ...
An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centers to the load centers , and the distribution system that feeds the ...
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network .
These substations may consist of two to eight or more primary transformers connected to the same secondary bus to provide reliable facility power. Examples of such single facilities include airports, hospitals, major data processing centers (especially those using uninterruptible power supplies), and sports arenas that regularly broadcast ...
Electric power distribution engineering covers those elements of a power system from a substation to the end customer. Power system protection is the study of the ways an electrical power system can fail, and the methods to detect and mitigate for such failures. In most projects, a power engineer must coordinate with many other disciplines such ...
The basic theory for how FACTs devices affect the AC system is based on analyzing how power transfers between two points in an AC system. This is particularly relevant to how an AC electrical grid functions, as the grid has numerous nodes (substations) that lack sources or loads.
