The solution will enable compression status to be monitored in the control room of Premier Powers’ gas-fired electricity generating station B at
Denca has previously worked with Premier Power on a number of contracts over recent years, including programmable logic controller (PLC) surveys, upgrade recommendations and networking surveys.
In this latest application, Denca was asked to develop a new control terminal solution that would enable full remote control of the power station’s three Atlas Copco air compressors used for all instrument air supplies.
The solution provided by Denca included Rockwell Automation’s RS View SCADA software interfaced into the Allen Bradley SLC PLC DH+ network via Modbus communications and Canbus communications to each of the three field-mounted Atlas Copco bespoke human machine interfaces (HMIs).
The system involved full software design, SCADA graphics event and alarm logging, and commissioning of the system without any instrument air system down time.
