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.
This is a list of electricity-generating power stations in the U.S. state of New Mexico, sorted by type and name.In 2022, New Mexico had a total summer capacity of 10,230 MW through all of its power plants, and a net generation of 40,889 GWh. [2]
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:
Jun. 19—There are some ways to help people affected by the fires in and around Ruidoso. —The Albuquerque Police Department is collecting donations at its substations across the city, starting ...
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 transformers reduce the voltage to a lower level for distribution to customers. This distribution is accomplished with a combination of sub-transmission (33 to 138 kV) and distribution (3.3 to 25 kV). Finally, at the point of use, the energy is transformed to end-user voltage (100 to 4160 volts).
In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system.. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
