Case Study:
NMS RTU Configuration Upgrades Across Nine Substations
Client:
Siemens / Network Rail / Thameslink
Project
Partner:
WJ Project Services
Location:
East Coast Mainline – London to Newark (9 Locations)
Scope:
RTU configuration upgrades, outage management, switching schedules, substation bypass, and NMS integration testing
WJ Project Services was commissioned to complete the full implementation of the Network Management System (NMS) across nine East Coast Mainline substations. The works focused on upgrading Remote Terminal Unit (RTU) configurations to enable full monitoring and control functionality from the York Electrical Control Room.
Outages were coordinated for each site, with detailed switching schedules developed to maintain alternate feeding arrangements. Substations were switched out or bypassed as required, with all plant operated and verified before installation of updated RTU configuration files within the Fastflex processing units.
Following installation, local testing was completed to verify system functionality before reinstating substations. End-to-end testing was conducted from the York Control Room to confirm full SCADA and NMS integration, ensuring accurate monitoring and operational control of HV assets.
Fastflex RTU processing units and NMS interface systems were upgraded, enhancing real-time monitoring capability and improving operational visibility of HV switchgear across the route.
The project successfully delivered fully integrated RTU upgrades, enabling reliable remote monitoring and control of substations and supporting efficient long-term network management.
