The Next Evolution of Substation Automation
For decades, protection and control in substations relied on dozens of hardware IEDs. Today, grid operators face new realities: more renewables, tighter cybersecurity rules, and a shrinking pool of specialists. The answer is a new architecture – virtualized Protection, Automation & Control (vPAC).
The Welotec RSAVP is the high-performance compute platform built to power this transformation.
From IED Hardware to Software-Based Protection
The RSAVP replaces traditional protection devices with virtual protection applications running on a single, substation-hardened server. Functions like:
- Distance and differential protection
- Interlocking and automation logic
- Control and switching
- Protection data processing
…run as virtual machines, delivering unprecedented flexibility and speed.
Why RSAVP
- Up to 64 cores & 512 GB RAM – built for real-time protection workloads
- IEC 61850-3 & IEEE 1613 certified – fully substation-ready
- PRP/HSR redundancy – zero-packet-loss during faults
- Redundant architecture – seamless protection failover
- Consolidation – replaces dozens of physical IEDs
With fewer devices, utilities gain simpler engineering, faster commissioning, and easier lifecycle management.
A Future-Proof Platform for Digital Substations
With RSAVP, utilities and system integrators can:
- Deploy centralized protection systems
- Reduce operational complexity and hardware footprint
- Strengthen cybersecurity with unified VM patching
- Meet growing regulatory and performance demands
Welotec RSAVP enables the shift from hardware-centric designs to software-defined substations — the foundation of a smarter, more resilient energy grid.
