SELLA CONTROLS to supply distributed TRACKLINK® RTU solution for Rotherhithe Switching Station

June 2018

Stockport, United Kingdom - Systems integration specialist SELLA CONTROLS is pleased to announce the contract award by Lowery Limited to supply the associated SCADA Works for the new Switching Station at Rotherhithe.

Lowery have been successfully delivering rail engineering projects since 1998 to Network Rail and the industry supply chain. Lowery are contracted by BAM Nuttal, the main contractor for the works.

The contract covers the complete design, engineering, build, installation and commissioning of a Tracklink® RTU and associated modifications to the existing traction power SCADA system at Lewisham ECR. Using the Network Rail accepted Tracklink® RTU solution, SELLA CONTROLS will be supplying a solution with a distributed architecture.

The new Rotherhithe SS will be supplied in two modular substation buildings controlled/monitored via telecommunication links from South Bermondsey. In addition to this a number of control and indications need to be exchanged between the Network Rail and National Grid substations. As a result the Rotherhithe SS RTU is distributed across the installation in three cabinets. A main control cabinet and two remote I/O cabinets. These cabinets are interconnected via a fibre network providing diverse routing of control and indications for the substation.

Central to the Tracklink® RTU solution is a COTS based PLC supplied by Mitsubishi Electric. The Q Series PLC provides the RTU with its intelligence and control and consists of core processing (CPU), Communications and I/O Modules. The distributed architecture will use the Q Series CC-Link high speed network over the fibre to facilitate the connections between the cabinets.

Chris Elliott, SELLA CONTROLS’ Business Development Manager for Rail commented: “This is a significant project for Sella Controls Limited. It is providing us with a platform to demonstrate the flexibility of our Tracklink® RTU solution. Space within new and existing substations is a premium and being able to supply a distributed I/O RTU solution gives great benefit to our clients.”

Elliott added further: “We are looking forward to working with Lowery on this project for Network Rail. We know how critical this project is to the IP Southern power supply upgrade program and we want to ensure that the commissioning date is met.”

The Tracklink® RTU solution is scheduled for factory acceptance in July 2018 before being delivered to Lowery for installation into the substation buildings.

Lowery have a reputation for quality and service that goes back over 65 years. As a Principal Contractor, they undertake Signalling, Telecoms, HV, DC, LV electrical installations and civil engineering works of all types whilst continually responding to market changes and developments.
