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.
While most devices and consumer electronics rely on AC energy for power, portable substations continue to operate on DC energy. DC supply has been widely used in substations and portable power applications for many years. The primary reason for using a DC supply in substations is to ensure a continuous power supply throughout the control circuit.
Power substation can have one or several DC systems. Factors affecting the number of systems are the need of more than one voltage level and the need of duplicating systems. Today, normal DC auxiliary supply systems in power substation are operating either on the 110 V or 220 V level, though lower levels exist.
The primary reason for using a DC supply in substations is to ensure a continuous power supply throughout the control circuit. DC power is reliable, easily directed from a battery source, and facilitates portable substation solutions. DC power remains a reliable source for portable applications.
Today, normal DC auxiliary supply systems in power substation are operating either on the 110 V or 220 V level, though lower levels exist. Some systems at the substation may require lower voltages as their auxiliary supply source.
In a power substation, DC supply is used for opening and closing circuit breakers, activating protective relays, isolators, indicator lights, alarm circuits, PLCC (POWER LINE CARRIER COMMUNICATION) panels, and control room emergency lights. Protective devices respond more immediately to DC supply compared to AC.
