Siemens virtualized protection for power grids cuts costs, saves space in digital substations
Virtualized Protection and Control solution with Siprotec V: Siprotec V is the virtualized version of Siemens' established Siprotec 5 protection and control device, designed for digital substations. This innovative solution allows for simple, scalable, and secure power grids, and can accelerate project execution by up to six months.
Siemens Smart Infrastructure has introduced Siprotec V, the virtualized version of the proven Siprotec 5 protection and control device. This innovative solution is designed for digital substations and enables simple, scalable, and secure power grids with up to six months faster project execution.
As global electrification
progresses and energy demand rises, existing grid infrastructure faces
unprecedented pressure. Energy providers expect to double their grid capacity
in the next decade while modernizing aging infrastructure. To meet these
challenges, technological innovations, automation, and standardization are
essential. Siprotec V addresses these demands: accelerating digital
transformation while ensuring resiliency and futureproofing of the power grid.
Scalability, simplification and security are all you need
Siprotec V breaks
traditional dependencies between protection and control software and embedded
devices. With its software-defined approach, it enables protection and control
applications to scale virtually within a substation — supporting centralization
of up to 60 virtual intelligent electronic devices (IEDs). This flexibility
allows utilities to adapt protection architectures efficiently to evolving
network demands, while optimizing valuable space savings of approximately 45%.
Due to
virtualization, Siprotec V makes it possible to fully test substation setups
digitally before they are commissioned. This simplifies the installation
process, speeds testing, and minimizes errors. Siprotec V's modular software
architecture allows rapid adaptation to evolving system requirements,
unconstrained by the limitations of hardware. This facilitates seamless deployment
of software updates, patches, and functional enhancements.
Sustainable and intelligent decision-making
Virtualization reduces the need for numerous panels, expensive copper cables, and costly physical installations including cable trenches. This slashes carbon emissionsup to 50% per substation, supporting a more sustainable energy industry. Additionally, virtualization delivers cost savings of up to 25% by reducing installed protection and control devices.
Furthermore, Siprotec V enables hosting
advanced AI applications directly in the substation environment, empowering
customers to unlock real-time insights, predictive analytics, and better
decision-making.
“Siprotec
is a name utilities trust. With Siprotec V, we take that trusted expertise into
the digital era — turning proven protection algorithms into a powerful
virtualized platform. This combination of real-world reliability and digital
flexibility is what makes Siemens the partner of choice for customers who need
to evolve their grids without compromise,” said Onyeche Tifase, Vice President of
Product Lifecycle Management at Siemens Smart Infrastructure.
Safe and resilient
Siprotec V
keeps our energy system safe through its consideration of leading cybersecurity
standards and features. The major drivers for secure infrastructure are
standards and guidelines, such as those outlined in the German Association of
Energy and Water Industries White Paper (Bundesverband der Energie- und
Wasserwirtschaft, BDEW) and North American Electric Reliability Corporation
Critical Infrastructure Protection (NERC CIP).
