Why is battery discharge testing important?
Due to this degradation, periodical Battery Capacity (Discharge) testing becomes necessary to ensure the optimum power backup from Battery Banks for the desired duration. Let’s dive into battery discharge testing—the backbone of effective battery care—guided by the recommendations from three key IEEE standards: IEEE 450, IEEE 1188, and IEEE 1106.
How is backup power provided in a substation?
Backup power can be provided by means of a mobile DC power system or through a backup battery bank at the substation. In cases where no backup power is available, an on-line discharge test can be performed. In this type of test, the regular substation load is always connected to the battery during the test and is continuously monitored.
Do battery banks need maintenance?
Periodic testing and maintenance of battery banks is imperative to ensure reliable delivery of power when they are called upon.
What is a battery energy storage system?
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
How does a substation load bank work?
In this type of test, the regular substation load is always connected to the battery during the test and is continuously monitored. The load bank maintains the desired constant current by regulating the remaining current needed in addition to the substation load current.
