What is a DC control power system for an electrical substation?

dc control power system for an electrical substation. I. INTRODUCTION The most critical component of a protection, control and monitori g (PCM) system is the auxiliary dc control power system. Failure of the dc control power can render fault detec-tion devices unable to detect faults, breakers unable to trip for fault

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 is the role of DC supply in substations?

DC supply in substations plays the role of a reliable source for current supply in the control circuit. It is obtained from the battery, which can store electricity power and continuously supply electricity till it’s not discharged. This makes DC supply an essential component for backup power in substations.

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.
