Digital twin helps protect smart energy grid
Siemens has developed a cloud-based digital twin of its grid protection devices.

The new cloud-based Siprotec DigitalTwin is the virtual digital twin of a real Siprotec 5 device with all the interfaces, functions, and algorithms. This allows the performance, safety, and availability of Siprotec 5 devices to be fully tested as part of the energy automation system, around the clock, from any location, and with no hardware.

Designing and commissioning a complex energy automation system are time-consuming processes and often can only be done after plants and systems have actually been set-up and connected to each other. For the 1.6m Siprotec devices installed around the world, this used to take days and sometimes even weeks.

The virtual digital twin allows tests to be carried out before or while setting up the hardware, reducing the time to system operation. Project data can now be simulated and tested individually in a cloud in just minutes, with no hardware or additional effort. This also lowers operating costs, since improved preliminary inspections can shorten downtimes and thus increase system availability.

"The digital twin of a Siprotec 5 device reduces the time it takes for our customers to connect new energy automation systems and lowers operating costs by shortening downtimes," said Ingo Erkens, head of Substation Automation & Protection within the Digital Grid Business Unit of the Siemens Energy Management Division. "The cloud-based application also significantly helps speed up and simplify fault clearance during troubleshooting."
