Today, normal DC auxiliary supply systems in power substation are operating on the 110 V or 220 V level. Battery, charger and distribution switchboard are
These supplies operate over a wide input range from 100-V to 450-V DC and keep system electronics powered under all conditions to detect faults such as undervoltage, overvoltage, and overcurrent. Typically, auxiliary power supplies generate multiple outputs delivering a power from
The higher (more important) role the substation plays from the complete distribution or transmission network point of view, the higher are the demands for the substation’s DC auxiliary power systems. To meet the increased demands for reliability and availability, the DC system can be doubled (Figure 3).
Generally Voltage of 240 V or 415 V AC is used. It is used for Essential Loads such as, Power Supply to Relays & Meters, Energizing Tripping and Closing Coils of Circuit Breaker, DC Emergency Lightning in Control Room, etc. Equipments used in Substation DC Power Supply System are as follows: Battery Set, Battery Charger, DCDB, etc.
This course has covered the design and application of AC and DC auxiliary systems used to support the operation of an electrical substation. In addition, the use of automation in substations was reviewed as well as the use of communications technology in substations.
