Design and Supply of Supervisory Control and Data Acquisition system for the London Underground Power System
London Underground is reassessing the ongoing suitability of existing ‘Power SCADA’ facilities, presently used to control and monitor traction power supplies; Power SCADA renewal/upgrade works will be required to carry out recommendations, to protect the business from excessive risk and to best prepare it for the future, in the interests of reliability and enhanced service and functional capabilities.

Section II: Object of the contract
London Underground presently utilises a number of disparate SCADA systems, each of varying age; each with its own maintenance, performance and capacity limitations. For the purposes of this notice, a summary of systems currently in use comprise:
— Supervisory Systems,
— ABB Spider (assume to be renewed),
— ABB MicroSCADA (assume to be renewed),
— Transmitton Cromos Xpress (assume to be renewed),
— 270 RTUs, based on single site occupancy.
O Each item of controllable plant communicating with the RTU either via IED, or a series of hard wired control and indication functions.
The use of modular, open, standard architecture, lending itself to regular ‘refresh’ programmes throughout its overall life and the ability to share data with other open systems, form a significant part of the requirements. The use of latest technologies and substation intra-operability will likely be embraced; security risks must be fully assessed and appropriate measures put in place to control and prevent unauthorised intrusion into the system. It may be assumed that the supply and installation of a new, dedicated fibre-optic communications network will also likely be required for effective control and data exchange; including intra-control centre and site data communications. Development and implementation of a migration strategy also forms a key requirement.
Potential future control and indication requirements will be in the order of 50 000 devices, whilst telemetering indication requirements will be upwards of 180 000 points.
As part of this Power SCADA renewal/upgrade programme, LUL is seeking expressions of interest from suppliers of SCADA and MES-related systems for the development, supply and installation of a system, and communications architecture, to control and monitor LUL’s traction power assets.
