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 the consumer, electric power may flow through several substations at different voltage levels.
Step-down substation: these transformers lower the voltage coming from the transmission lines which can be used in industry or sent to a distribution substation. Distribution substation: these transform the voltage lower again for the distribution to end users. Aside from transformers, other major components or functions of substations include:
Most of the world uses 50 Hz 220 or 230 V single phase, or 400 V three-phase for residential and light industrial services. In this system, the primary distribution network supplies a few substations per area, and the 230 V / 400 V power from each substation is directly distributed to end users over a region of normally less than 1 km radius.
Substation integration refers to combining data from the IED's local to a substation so that there is a single point of contact in the substation for all of the I&C data. Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion.
Substation: This is the part dealing with the different entities of a substation including various devices, interconnections and other functionalities. The elements include power transformers, Voltage Levels, bays, General Equipment, conducting equipment like breakers.
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 ...
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
