DC Power Supply System in an Electrical Substation

The battery bank provides the DC supply to load only in case the Battery charger breaks down or the AC supply to the battery charger breaks down. So in normal conditions, it is the charger that supplies DC power to protection,

Why Battery Bank is Used in Substation

Indoor Substation : The essential justification behind utilizing DC power supply in the control circuit is to provide a continuous power supply to the control hardware. Since DC power can potentially come from batteries, it is a reliable source.

Substation Battery Systems Present & Future

•The substation batteries for the DC system must be in operation 24/7 – 365 – NOT just for backup power, but also to provide the current needed for day-to-day switching operations •Charger provides current for the load & a float current to charge the battery

6 FAQs about [Battery bank in substation Greenland]

How are substation battery banks purchased?

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.

What are the different types of battery banks used for substation applications?

There are two major types of battery banks used for substation applications; lead acid and nickel cadmium. The nickel cadmium battery banks are about twice the cost of lead acid for the same size bank. The major advantage that nickel cadmium batteries have over lead acid is their performance in poor climatic conditions.

Where are battery banks purchased?

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. Lead acid battery banks are purchased as close to their required need date as possible.

What type of battery bank does JEA use?

JEA has standardized on lead acid type battery banks to supply this 125 volt DC requirement for its substations. There are two major types of battery banks used for substation applications; lead acid and nickel cadmium. The nickel cadmium battery banks are about twice the cost of lead acid for the same size bank.

How many DC systems can a power substation have?

A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.

What is an example of a low voltage substation?

Some systems at the substation may require lower voltages as their auxiliary supply source. A typical example of these systems would be the optical telecommunication devices or the power line carrier (PLC) equipment, which normally requires 48 V.
