Battery Monitoring And Maintenance (on photo: 110V substation NiCd battery system) Since those early days, a lot more has been learned about why and how batteries fail, To check the number and depth of discharges. This information is used to project battery life and settle warranty issues.
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.
Now, let's do some math and size a flooded cell, lead-acid battery for a substation. The battery will be rated 125V DC nominal and have an amp-hour capacity rated for an 8-hour rate of discharge. In most substations, the 8-hour rate of discharge is the standard.
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.
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.
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.
The substation battery banks are sized and purchased by the substation engineering activity. Battery banks are purchased direct from pre-approved battery bank manufacturers. Battery banks are purchased for individual substation projects and for replacement of deteriorated existing banks throughout the system as needed.
