Lithium-ion battery for back-up DC systems: no more worries about grid stability

Operational direct current system, but specialists most often use the term OOPT. This is a huge area of ​​various modern energy projects.Operational direct current system

Operational current providing power to the secondary circuits of the power plant or its substation (circuits of electromagnets for switching off and on switching devices, control devices, automation, signaling, protection and measurement, telemechanics and others).

The operating direct current system (DCS) provides power to the terminals of the automatic relay protection of various systems, automation operating in emergency mode, automated process control systems and control circuits for switching devices, automation and signaling in normal modes, for a certain time, with complete de-energization of the personal needs of the alternating current of the substation.

As a source of constant operating current, the OSS includes rechargeable batteries (AKB). Traditionally, such batteries were lead-acid batteries, but recently experts have begun to use lithium-ion batteries for these purposes.

The use of lithium-ion batteries in DC systems makes it possible to form a compact, and most importantly, safe system that requires minimal maintenance. The use of Li-Ion batteries, instead of lead-acid ones, helps to obtain a modern model of DCS, capable of maintaining a stable mains voltage and high discharge current.

The use of lithium-ion batteries in DC systems guarantees stable electricity even as a result of various failures and power outages of equipment in any production.
