6 FAQs about [New Energy Substation Battery Operation and Maintenance]

What does a battery do in a substation?

In a substation, the battery is commonly used to power the supply relay and breaker tripping mechanism. These monitoring device operations are ensured by a trustworthy battery power supply, leading to successful operation of that device.

How many volts a battery should a substation have?

Those batteries usually have a rating of 45 Ah (min), 24 V to meet the load requirement of the substation. Table 4.9 gives the cell voltage of different voltage level batteries and Table 4.10 compares the different types of batteries.

What should be included in a substation Handbook?

The emphasis has been given to include the operation and maintenance procedures of new and modern technology for substation equipment’s and protective relays. The efforts have also been made that this handbook shall be compatible with new International Grid code of some countries and with relevant IEC standards.

What is a power distribution substation?

A power distribution substation is the heart of an electrical distribution network. Its prime objective is to step down power at the 66 or 33 kV level and distribute it in an 11 kV subdistribution network . Normally these kinds of substations are located near load centers at the outskirts of cities.

What is a kV battery rating in a substation?

In a substation 33/11 and 66/11 kV rating system, the standard battery voltage rating of 30, 110, or 220 volts is deployed for storage usage. Those batteries usually have a rating of 45 Ah (min), 24 V to meet the load requirement of the substation.

What is the maximum capacity of a 33/11 kV substation?

The maximum capacity of any 33/11 kV substation will be 60 MVA, either indoor or outdoor type, and also either air insulated (AIS) or gas insulated (GIS). These substations are constructed per the Indian standard, and other rules and regulations as per the latest amendment issues by the Central Electricity Authority of India (CEA).
