Brazil, Sao Paolo: GE’s Grid Solutions have commissioned the first digital substation connected to Brazil’s National Interconnected System (SIN).
Owned by ISA CTEEP – Brazil’s largest private transmission company – the Lorena substation in Sao Paolo has a 1,200 MVA installed capacity and will benefit the entire Vale do Paraiba region, recognized as Sao Paulo’s main centre of technology. It will be able to fulfil the energy demands equivalent to the consumption of two cities the same size as Sao Jose dos Campos.
The Grid Automation team within GE’s Grid Solutions manufactured and commissioned this fully digital substation, including the grid automation and protection system with process bus technology. This technology allows ISA CTEEP to record measured values from the transformers, digitize and send them to protection devices. Digital data are easier to transmit and share between substation devices in real time, allowing for better data utilization.
“The Lorena substation represents a milestone in ISA CTEEP’s digital transformation towards the 4.0 substation, essential for increasingly decarbonized, distributed and digitized energy systems. With this new venture, we will significantly contribute to increasing the reliability, efficiency and sustainability of the Brazilian transmission system,” said Dayron Urrego, executive director of projects at ISA CTEEP.
The contract for the project, which has two transmission lines operating at 500 kV and four transmission lines operating at 230 kV, was signed in 2019.
