In phase 2 of a secondary distribution SCADA automation project, system integrator Lucy Switchgear have been working closely with the Electricity Company of Ghana to provide a full turnkey automation solution.

The majority of the work in this second phase has been concentrated on Ghana's second city Kumasi. Lucy Switchgear have provided and commissioned:

  • Retrofit actuators for existing ground mounted 11kV switchgear.
  • New pre-automated ground mounted 11kV switchgear.
  • New automated pole mounted switchgear for 11kV & 33kV air break switches.
  • A complete communications infrastructure using high power (5W) radio modems and repeater stations.
  • A dual redundant SCADA control system built on the iPower / iFIX SCADA platform

The aim of the second phase of this automation project was to automate key points on the Kumasi secondary distribution network to give immediate benefit to ECGs customers and control engineers. The major challenges currently facing ECG are traffic around the city making it very hard to quickly get to the required isolator or ring switch and need to quickly locate faults. Lucy switchgear have installed and commissioned a system of 50+ automated sites around the city which is providing immediate benefits. The system provided is also very scaleable so ECG can add in further automated sites as their network grows and control requirements change.
