Testing the capacity of DC current supply batteries for the first time in Esfahan regional electricity

In order to increase the batteries life of Esfahan regional power stations, the battery capacity measurement test was successfully performed for the first time at Jahan 230 kV station.

According to Isfahan Regional Electricity Public Relations, Mohammad Ali Ataei, the manager of the Technical Office of Operation Deputy, said: "Battery capacity test is a test in which, by determining the capacity of damaged battery cells that have lost their nominal capacity, Damage to other healthy cells is prevented, thus increasing the life of healthy batteries and improving the performance of the DC system.

Mr. Ataei added: The batteries of the stations along with the relevant chargers are responsible for supplying DC power to the protection and control equipment of the power stations and play an important role in the reliability of the system.

The manager of the Transmission Technical Office described the test steps, which was performed in five stages on 110 V batteries (52 cells) of the 230 kV Naqsh Jahan station, including: disconnecting the desired battery pack from the mains, measuring the voltage of each cell, measuring the battery pack voltage, measuring of the internal impedance of each cell and the measuring of the electrolyte concentration of the cells per hour for the rated current drawn from it until the voltage of the battery set reaches the minimum allowable value, which was done according to the instructions of the network management company.

Mr. Ataei added: The mentioned batteries made by MUTLU of Turkey are of Wet lead-acid (VRLA) type with a nominal capacity of 600 ampere-hours (OPzS600), which was installed and commissioned in 1994.

In the end, it need to be said: the batteries of the stations are responsible for supplying DC power, especially during the complete power outage of the station, and for powering the protection relays, control relays and PLC systems. The standard output voltage of the batteries is 110 V and 48 V DC, and existence of DC current is a requirement for the operation of the substations.
