Less copper

Benefits of digital substations

October 15, 2019 * in transmission level AIS substationsSlide 10

– By replacing copper cables between switchyard and relay house by fiber optics

– By replacing horizontal wiring between protection and control IEDs with IEC 61850

– By reducing number of connections between primary apparatus and redundant process interfaces modules

– Copper cables remain for power supply and short connections between primary apparatus and marshalling kiosks in the switchyard.

Point to point copper connections get replaced with fiber optic communication network

Reduction in copper cables by up to 80%* Conventional substation Digital substation

Up to

80% copper cable

Weight reduction



AIS

– More than 30 tons material can be saved for an average sized transmission level substation with 7 feeders

– The weight of the fiber optic cabling is around 90% less than the copper cables it replaces

– By using optical instead of conventional CTs almost 80% weight reduction on CTs is achieved

GIS

– GIS weight reduced by up to 12%

– The SF6 weight reduced by up to 10%

Less transport, less CO2, less heavy lifting equipment required

30 tons less materialConventional substation Digital substation

Less space in relay room



60% and more reduced space for protection and control panels

– The IEDs require less space due to absence of conventional IOs

– Absence of terminals enable integration of more IEDs per panel

– Integration of more functions in IEDs enables further space reduction

High function integration, smaller IEDs and fewer conventional components enables space reduction

Space requirement reduced by half Conventional substation Digital substation

Up to

60% less space in relay room

Less space in switchyard



Reduction of AIS switchyard footprint by up to 50%

— By using circuit breakers with integrated disconnecting functionality and optical current transformers

Reduction of GIS footprint by up to 30%

– By using NCITs for current and voltage

– By integrating LCCs to GIS switchgear

High function integration and NCITs enable space reduction in the switchyard

Shorter installation time



40% reduction of installation time for new protection and control systems.

– Fewer panels to install

– Fewer cables to be pulled, connected, tested

– More testing in the factory means less testing on site

Shorter installation time decreases project runtime

Shorter time for secondary system installation Conventional substation Digital substation

Shorter outage time during secondary system retrofits



Reduction of feeder outage time by 40 to 50% during secondary system upgrades

– Full system test from process IO to protection, control and SCADA system off-site

– Installation of new FO based system while station is in service

– Flexible placement of new protection panels, without depending on SS cabling

Shorter outage times increase system availability and utility revenues

Operational cost reduction



Efficient maintenance

– Supervision of all exchanged data, reduces the need for periodic maintenance testing

– Permanent supervision enables fast and precise actions in case of failures

Fast and save testing

– IEC 61850 testing and simulation features enable fast and safe isolation and testing of protection functions

Standard compliance enables efficient future retrofits of secondary system

Lower operational costs thanks to supervision and standards

Savings in maintenance and future retrofitsConventional substation Digital substation

Increased safety



– Handling of current transformer circuits and signaling voltage poses a threat to life and equipment

– Process bus eliminates the galvanic connection between protection and control panels and the switchyard.

– Eliminates CT and VT circuits in the protection & control panels

– Replaces conventional 110/220VDC indications with fiber optics

Eliminates the electrical connection between primary and secondary

Reduced risk of electrical shock
