AC auxiliary systems are critical in a substation. AC power is used to provide load requirements for different equipment and lighting fixtures. The designer may perform a load analysis on all the AC loads in the substation in order to decide whether a single-phase or three-phase source is needed.
Substation auxiliary power supply System: The Complete Guide ! We know that Substation is a place where Power Flow/Transmission takes place, but it also, has its own Power Consumption. The purpose of Auxiliary Power Supply system in the Substation, is to Power-up/ Energize various Electrical Equipment/Devices used in the substation and the yard.
Most substations are provided with two sources of station service AC power. The two sources of station service power are generally designated as the primary source and the alternate (or backup or secondary) source. Both sources should be of equal reliability.
Some loads may be identified as critical, which requires AC service to be maintained at all times. Depending upon such critical loads, the substation may require two AC station service sources with the ability to transfer loads between sources. System stability considerations are important for the reliability requirements of the station power.
The three component parts of the substation are defined as follows: Primary, Secondary, and Auxiliary System. Let’s remind ourselves of these three basic substation systems: Primary System: The primary system comprises all equipment that, in whole or in part, is in service at the highest operating voltage of the system.
The standby backup AC system used in substation normally consists of a diesel generator. The diesel generator is normally used in the substation for one of the following reasons: Used as back up to the primary source, when only one source is available and the substation requires two redundant AC sources.
