ABB has won a contract to deliver what it claims will be the world’s largest digital substation.

It is to upgrade an air insulated substation in Belarus for the country’s Ministry of Energy and its transmission utility Mogilevenergo.

As part of the upgrade, the substation will be equipped with digital technology that is intended to enhance controllability and reliability while optimizing operating costs.

ABB will supply protection and control equipment, its ABB Ability MicroSCADA system and a digital process bus, which enables communication through ethernet cables instead of copper wires, saving cost and space.

As part of the project, ABB will also supply digitally enabled high-voltage products like fibre optics current sensors and disconnecting circuit breakers to the substations EPC company, RIKO.

Belarus has a population of more than nine million and borders five countries. It is experiencing growing electricity demand and its power grid is evolving to meet this need. ANN said digital technology is considered to be a key pillar in coping with future changes related to both power generation and demand and digitalization “enables unprecedented visibility of a customer’s assets and systems and the efficient harnessing of extensive volumes of data”.

Massimo Danieli, head of ABB’s Grid Automation business within the company’s Power Grids division, said: “We are pleased to support Belarus’ digital substation, reinforcing our position as a partner of choice for a stronger, smarter and greener grid.”

He added that digitalization “enables the easy integration of IT and OT systems enabling operators in control centres to interpret key insights in real time and as a result prevent critical failures”.

“With increasing numbers of smart sensors in the field, the amount of process data being collected and analyzed within the substation is increasing correspondingly, allowing for protection and control, or for condition monitoring where the data is run against predictive models and machine learning in the cloud.”
