The “Digital Twin” – A virtual copy of a physical asset

▪ The digital twin integrates all data, models, and

other information of a physical asset generated
during engineering, commissioning, operation, or
service.

▪ The role of the digital twin is to predict and

optimize performance of a physical asset (whether
for design, production or operation).
To this purpose, we use simulation methods
and/or data-based methods.
What are the benefits of Digital Twins?

Testing of the energy automation system within minutes, without hardware

and without additional effort
• Simulation and validation of product properties
• Faster energization of new systems thanks to shorter project lifetimes
• Increase engineering quality
• Virtual testing before start of commissioning
• Shortest commissioning times
• Reduced OPEX with shorter outages for higher availability thanks to better pre-testing
• Efficient, scalable trainings on the job
• Fast and realistic fault analysis by easily reproducing the behavior of products and systems

Example of wiring for a central busbar protection device

““The DigitalTwin proved to be an excellent environment
for testing the protection system. I was able to perform
all the tests I wanted and the device simulation always ran
smoothly. The environment is a really great development
from Siemens and there will certainly be many more future
possibilities when working with the DigitalTwin.”

“Utilising a Digital Twin reduces the required floor space,
significantly save on engineering time setting up and
wiring the physical hardware, and provide efficiencies in
project delivery of the expansion scope.”

Fault record replay and FW selection
““The use of DigitalTwin was a success, it was possible to
identify that the bad performance of the relay was due to
its firmware, this way we could take the necessary
measures in time and avoid that this type of events would
cause the trip of new devices.
We can see a great potential in this tool that will be of
great use to us, and much of our work in the field can be
developed in the laboratory and maintenance times in
the field could be reduced substantially.“

Summary and Outlook

▪ Digital Twins have long been used in the industry.

▪ New technologies enable more flexible and scalable use of

Digital Twins, which will result in greater benefits and thus a
wider use

▪ With DigitalTwin, time and costs in engineering, operation and

maintenance can be reduced

▪ Virtual simulation of complete substations will be possible

through interoperable interaction of manufacturer-specific digital
twins via standardized communication interfaces
