The 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.
BESS at primary substation Battery energy storage system may be connected to the high voltage busbar (s) or the high voltage feeders with voltage ranges of 132kV-44 kV; for the reliability of supply, substations upgrades deferral and/or large-scale back-up power supply.
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.
A typical high-voltage industrial/utility substation DC system consists of a flooded-cell battery bank (see TB001) and a battery charger(s). Too often, too little attention is given to the proper application of the battery charger. Under normal operating conditions, the battery provides very little current.
Batteries are to be accommodated in a cabinet within the substation control room - separate battery rooms are not required. Cells are to be mounted in accordance with the manufacturer's recommendations regarding separation between cells to allow air-flow for cooling and for easier access for removal if necessary.
