Powerco Gas Reticulation Cellular SCADA System
Powerco awarded Abbey Systems a significant contract in 2009 for the supply of a SCADA system monitoring 70 key gas distribution sites in their network across the Lower North Island, New Zealand. These sites regulate the supply pressures and flows into the reticulation network. The project uses GSM cellular communications back to a virtualised SCADA Master. The system timestamps and stores pressures and flow data onsite and automatically Alarms to cellphones when pressures are outside upper and lower limits for each site. Operators use Abbey Systems' Securelink to access their data, allowing multiple users access to the system at the same time.
