ABB to work on Poland’s first digital substation [free access]

September 25, 2017

Poland's power utility Tauron Distribution SA has awarded a contract to ABB for the upgradation of the 110 kV substation in Oborniki lskie town in south-western Poland. Once completed, this will be the first digital substation in Poland.


Under this contract, ABB will upgrade the 110 kV switchgear, and protection, control, measurement and telecommunication systems. The company will use optical fibre cables in most of the communication links to increase the data transfer capacity as well as transmission safety and security. The 110 kV substation will also be equipped with fibre-optic current sensors designed to monitor electricity flow.


The project is expected to enhance controllability and reliability of the substation, which distributes electricity to the network's most distant locations.
