Network architecture diagram for Muong Muon hydropower plant’s control and protection system. The layout depicts a redundant network topology with dual LAN networks (LAN A and LAN B) for increased reliability. Key components include:
Network Infrastructure:
– Two S20 switches forming the core network infrastructure
– Redundant HSR (High-availability Seamless Redundancy) rings for fault tolerance
– Redbox HSR devices providing protocol conversion between networks
Control Components:
– Three IED (Intelligent Electronic Device) units connected in series at the field level
– RMS (Remote Monitoring System) at the supervisory level
The design implements IEC 61850-compliant architecture with HSR protocol ensuring zero recovery time during network failures. Drawing created January 2024 for the IT202401_HPP_CRP project under contract TB05-MM/2023/HD-ENOC-ITECHS.
