Distribution network visibility

Start date: March 2011 End date: Low Carbon Networks Fund: £2.89 million

Electronic devices (also called Remote Terminal Units) are used to reconfigure and collect data about the performance of our network, so we can intervene when necessary to keep supplies safe and reliable. This project is exploring better ways to collect and use the data we gather such as demand, capacity and faults on our electricity network.

Improving our remote telemetry is key to a ‘smarter’ electricity network which responds to swiftly changing electricity demand and generation. Improvements to our IT architecture mean we can now collect and store more data to gain a better live picture of how our network is performing. The challenge in this project is enhancing those capabilities.

  • Maximise the capabilities of remote telemetry (Remote Terminal Units) at our substations
  • Demonstrate the benefits of smart collection, use and visualisation of data
  • Use software to improve our understanding of network performance
  • Evaluate alternative solutions for sites in the South East and East of England
  • Decide what data should be collected and how often
  • Provide further sources of data for the Low Carbon London project
  • Share our findings with relevant groups

Our research will cover Remote Terminal Units, low voltage monitoring, systems, communications and IT.
  • Real-time power flows on the high voltage power network
  • Clearer demand profiles to help plan network reinforcement schemes
  • Improved management of secondary substation ventilation
  • Better, more cost-effective application of maintenance policies
  • Support the connection of new load and renewable generation

In summary, this project will cover the following:
