New switchgear for higher reliability of power grid

Germany, Lonsee: GE Renewable Energy’s Grid Solutions business energized a new 123 kV, 16.7 Hz switchgear for DB Energie GmbH’s train station.

The 60-year-old Amstetten train station located in Lonsee between Stuttgart and Ulm in Germany.

Developed as part of the EU-funded IN2STEMPO project, the digital hybrid compact switchgear is a first-of-its-kind.  IN2STEMPO is developing a smart railway power grid with an interconnected system that integrates smart metering, innovative power electronic components, energy management, and energy storage systems.

“We are pleased to be a part of the IN2STEMPO project. Our flexible digital HYpact solution can be used in several applications – from mobile (truck-mounted) substations to onshore wind substations. Basically, it helps make the unpredictability of the electrical network more predictable, while reducing the customer’s operational costs, as well as their impact on the environment,” said Eric Chaussin, GE Renewable Energy’s Grid Solutions High Voltage Products Leader.

The switchgear is fitted with digital power sensors using very sensitive low power instrument transformers and it provides remote monitoring of the grid’s status from a control room.

In a modern digital substation, copper cables are replaced by optical fibre cables, which will allow DB Energie to lower its total carbon footprint.
