  • Transmission IFI projects

  • In April 2013, Ofgem replaced the Innovation Funding Incentive (IFI) with the Network Innovation Allowance (NIA) for electricity transmission network operators.
    Our open IFI projects have transferred to the NIA and you can read about them here. Our closed IFI projects are summarized below,  and you can download the Closedown Reports in the Library.

    IFIT 2007_02: Flow Battery Trial
    The provision of DC auxiliary supplies at transmission substation sites has almost exclusively been provided by lead acid batteries. New technologies are now emerging which may offer superior performance with reduced maintenance costs but there has been limited operational experience within GB to date. This project installed the first flow battery on the UK network in 2009; this was later shut down due to multiple issues. SHE Transmission are working with EA Technology Ltd. to analyse the results.
    IFIT 2009_04: Mobile Condition Monitoring System for Open Busbar Transmission Substations
    This technology can gather condition information whilst maintaining a high level of safety to facilitate decisions on replacement of plant based on accurate assessments of condition rather than age. Data sourced from site trials with the PD trailer were found to be variable and may be too complex for simple extrapolation into maintenance procedures.
    IFIT 2010_01: ACCC Peterhead – St Fergus Transmission Reinforcement
    This project completed the first installation of an Aluminium Carbon Core Conductor (ACCC) in the UK. The ACCC can run at higher temperatures with a lower sag and greater capacity, allowing up-rating of existing lines with reduced strengthening of towers and foundations.
    IFIT 2011_02: Collapse Prediction Relay (CPRD)
    The project evaluated a new type of protection relay which is claimed by the manufacturers to be able to predict a possible transmission power system collapse at an early opportunity. The CPR-D relay was assessed in a laboratory at the University of Manchester and whilst installed at suitable location on the GB electricity transmission system. Whilst the relay can detect system abnormalities it is not able to differentiate between normal disturbances and potential system collapse situations. The device is able to detect large voltage disturbances but it is not able to determine the cause or provide location information relating to a disturbance. Results from installation on transmission system show that the relay was triggered by local switching events. They also show that the device was unable to detect oscillations that were able to be detected by other devices installed on site. This project concluded that the device does not have the ability to predict system collapses.
    IFIT 2011_03: Wide Area Monitoring Protection and Control (WAMPAC)

    The project commenced in 2008 and ran through to 2011. The key deliverable elements of the project included:

    Year 1: A review of existing WAMPAC solutions, a study of WAPMPAC technology worldwide and an evaluation of real systems installed elsewhere in the world (Denmark, Sweden. USA). Identification of technology which will be suitable for installation on the GB and IRL transmission network. Evaluation of system architecture requirements, based on the applications aimed to be implemented (short-, mid- and long-term). Evaluation of the current state of technology used for WAMPAC systems including the assessment of the compatibility of existing technology (assets) related to the needs of a future WAMPAC system. Review of future physical connection requirements and challenges with the maintenance of the hardware, supporting a GB and IRL WAMPAC system.

    Year 2:Development of a simulation tool based on DIgSILENT, for investigating WAMPAC systems. Investigation of different models with different levels of complexity was used. Evaluation of WAMPAC algorithms on a simulator that models GB and/or IRL network.

    Year 3:Design and evaluation of new WAMPAC algorithms for improved network monitoring and control. Evaluation of WAMPAC algorithms using data from PMUs on GB and IRL network. Benchmarking, validation and fine-tuning of models used in the project (DIgSILENT). Final report and presentation of PhD thesis. The research was concluded successfully and further wide area monitoring protection and control projects are likely to follow

    IFIT 2012_01: Bellrock Lumen-Condition Monitoring Decision Support
    This project aimed to formalise requirements and demonstrate how Bellrock Technology's intelligent decision support platform, Lumen, could assist engineers to monitor and manage their critical assets. Specifically, the project focussed on the management of power transformers. Lumen is currently being piloted by Maintenance and Major Projects teams.
