telemetry telecontrol
Telemetry & Telecontrol
  • 4000 gas & electricity, and 8000 water ST assignments
  • 4000 terminals on dedicated London Electricity data system
  • More systems going in every day (on existing frequencies)
  • 24/7 – 60/365 systems
  • ‘continental interference’ overcome by engineering solutions
  • No interference problems since 31 December 1999
  • Widespread geographic deployments

SMAG FORUM 24 OCTOBER 2003

challenging changes
Challenging Changes
  • Some equipment can be remotely re-configured over the air
  • Some equipment needs site visits to change frequencies and/or filters
  • Some sites need ‘permit to work’ before entry
  • Most sites governed by HSE rules on who may enter
  • In many cases, parallel working will be required during changeover
  • Predominant cost is labour cost – site visits
  • Logistics can be expensive

SMAG FORUM 24 OCTOBER 2003

challenging issues
Challenging Issues
  • Parallel working:
    • Spare channels? Combiners/second antenna? Space on mast? Space in cabin? Equipment cost? Is anybody else doing same? Planning cost?
  • National Co-ordination:
    • Are all channels available everywhere?
    • Cannot accept geographic restrictions
  • International Co-ordination:
    • Will there be power restrictions? Preferred channels? Coordination delays?
  • What are we sharing with:
    • Will we get more interference on the new channels than the old ones?
    • How will 12.5kHz FM, 25kHz Tetra, 200kHz CDMA share across borders?
  • Intermods on shared sites:
    • How to predict? Who is responsible for resolution? Who pays?
  • Interference & blocking on shared/adjacent/near-by sites:
    • How to predict? How to resolve? Who pays?

SMAG FORUM 24 OCTOBER 2003

challenging conclusions
Challenging Conclusions
  • The problem must be soluble, ….but
  • Need to identify problems in order to solve them, … and
  • The process will need careful preparation and planning. And oh yes …
  • The cost of the new equipment is the cheap and easy bit.
  • Need to look at operating licences in some cases (eg Magnox Electric)

Some facts to ponder from reports issued in September 2003:

  • Average availability of power from NGT is 99.9999%
  • “A delay occurred in the restoration of one section of Aquila’s network due to failure of a SCADA (telemetry) link” (OFGEM Report 30 September 2003)

There are a lot more challenges, but …

that’s enough from me!
