Virtualized Substation Automation Systems
Euto Energy’s vSAS is a fully software-defined automation platform designed to modernize critical substations for DSOs and TSOs. By virtualizing the entire protection, automation, communication, and control layer, vSAS drastically simplifies infrastructure, improves interoperability, and accelerates deployment. Instead of relying on dozens of fixed-function hardware devices, operators can manage and scale their grid with a few high-performance edge computers – unlocking flexibility, intelligence, and cost efficiency.
vPAC – Virtualized
Protection, Automation & Control
vPAC is the core intelligence layer of vSAS. It replaces traditional protection relays and control systems with software-defined modules that run on standard hardware.
For DSOs, vPAC enables faster upgrades of congested distribution networks without waiting years for grid reinforcement.
For TSOs, it provides high-speed, deterministic protection and real-time orchestration across transmission substations.
It supports IEC 61850, IEC 60870-5-104, DNP3, Modbus and MQTT protocols, enabling seamless integration with any vendor’s infrastructure.
It delivers sub-millisecond process-bus capturing and protection response, adaptive automation, and AI-based fault prediction.

vRTU replaces legacy RTUs with a software-based, interoperable communication layer. It acts as the bridge between field devices and the control center, ensuring secure and real-time data exchange, enabling further flexibility and intelligence.
For DSOs, it allows easy and granular integration of distributed energy resources (DERs), EV chargers, and flexible loads at the medium- and low-voltage levels.
For TSOs, it provides high-speed granular communication for complex protection schemes and wide-area protection and control.
vRTU eliminates vendor lock-in, simplifies engineering, and reduces maintenance and operational costs significantly.
vRTU unlocks the integration of flexibility and intelligence into the operation and enables digitalization safely.

vHMI – Virtualized Human-Machine Interface
vHMI provides operators with a unified, real-time visualization and control environment. Unlike traditional dashboards, it is built as part of the automation engine, ensuring instant response without latency.
DSO operators can view, control, and reconfigure multiple substations remotely from one interface.
TSO control rooms gain full situational awareness with advanced alarm management, logic visualization, and secure role-based access.
vHMI is cloud or edge-hosted optionally, enabling hybrid on-prem and remote operations for maximum operational flexibility.
