Learn MoreThe primary role of the substation battery system is to provide a source of energy that is independent of the primary ac supply, so that in the event of the loss of the primary supply the substation control systems that require energy to operate can still do so safely.
Substations with duplicated protection systems shall have dual (2) battery systems - one for each protection system. Substations that do not have remote back-up protection systems shall also have dual battery systems. Substations without duplicated protection systems, and which have remote back-up protection, shall have a single (1) battery system.
The battery is required to supply the DC electrical requirements of the substation, including SCADA, control, protection indication, communications and circuit breaker switching operations when there is no output from the battery charger. This may be due to a loss of AC supply to the substation or a fault in the battery charger.
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
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.
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).
