How many DC systems can a power substation have?

A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.

What voltage auxiliary supply system is used in power substation?

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

What is DC supply in electrical substation?

So let’s start with the application of DC supply. DC supply system in an electrical substation has a very important role in keeping the substation’s brains on. Meaning all modern numerical protection relays, closing tripping coils, alarms, hooters, Indications & communications devices are powered by DC. Also, some energy meters are powered by DC.

Why do substations need DC auxiliary power systems?

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).

What voltage is a DC auxiliary power supply?

Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.
