Operation of abb energy storage circuit breaker

What is a solid-state circuit breaker (ABB)?

A technological breakthrough by ABB – a solid-state circuit breaker – will enhance performance of renewable energy solutions, industrial battery storage solutions and so-called edge grids.

What is a solid-state circuit breaker?

The solid-state circuit breaker will be around 100 times faster than traditional electro-mechanical breakers. Its speed maximizes the performance of power distribution systems, while maintaining service continuity. The new ABB breaker will also improve safety and protection for people and equipment.

How does a solid-state breaker work?

The ABB solid-state breaker concept works by replacing the traditional moving parts of an electro-mechanical circuit breaker with power electronics and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.

How does ABB's onboard DC gridtm work?

DC power distribution has been gaining momentum in marine vessels, where the ABB’s Onboard DC GridTM architecture has proven to enable fuel savings up to 27% [23, 24]. Here, as shown in Fig. 3.36, a bus tie breaker connects the two starboard and portside sections; this typically allows an optimal and redundant usage of the power generators.

Can a solid-state circuit breaker save you money?

For example, in the event of an electrical fault in a 4MW utility-scale battery system, the new solid-state circuit breaker can prevent losses of up to $100,000 per plant from missed energy remuneration and system recovery costs.

What is a model based sscb breaker design?

SSCB breaker design is a tedious process and involves multiple components. A model-based design provides deep insights into the SSCB protection process and theoretical foundation for selecting parameters of each component inside the breaker.
