Growing urbanization rising energy demand and increasing costs have further motivated the power sector to utilize their electrical system capabilities more efficiently and smartly – toward smart substation transformation.  The three main challenges of grid modernization are climate change driving extreme weather events impacting electrical grid changes, increased risk of cyberattacks on grid infrastructure, and high penetration of renewable energy sources which increases power flow complexities.

The Virtual Protection Relay (VPR) concept is an essential building block for grid modernization, offering a solution for protecting complex power distribution substations.  Through an architecture where software-defined and virtualization platforms come together to deploy critical circuit protection functions, simplify life cycle management to increase performance, and reduce CAPEX and maintenance costs; to deliver reliable, resilient electricity supply for the future.


A VPR solution can reduce the physical size and complexity of a substation infrastructure, reducing CAPEX costs, in addition to increasing flexibility of deploying protection functions and automation algorithms for strengthening performance and reducing maintenance costs. The VPR solution builds upon the IEC 61850 standard and key requirements include:

  • Industrial-grade IEC Certification – The network appliance needs to be IEC 61850-3 and IEEE 1613 compliant to withstand harsh critical infrastructure environments and is specially designed for power substations.
  • High-Availability – A reliable power supply is essential and a redundant power path ensures continuous operations and uptime for an extended period.
  • Scalable – Rich I/O functions, scalability, and expansion features are needed for better performance even as demands increase, including swappable drive bays, PCIe slots for time sync cards, or industrial-grade NICs.
  • Multi-layer Hardware Security – Onboard TPM for secure crypto-processing and tamper resistance at the hardware level.
