Visualization and control of three power plants in Nigeria

February 9, 2016 | Reliance SCADA

In 2015, Alpha Engineering installed a SCADA-based system for power plants at three locations in Nigeria: Mainland Power Plant Lagos, Luth IPP, and Pabode Power Plant. In total, these power plants contain 17 Cummins natural gas and diesel gensets and provide power to Lagos Airport, government offices, and the nearby area.



Control system

The Reliance SCADA/HMI system and two PLCs (Mitsubishi MELSEC-Q Series and Siemens SIMATIC S7-1200) are used to monitor and control all the gensets (Cummins QSK60 Gas and Cummins KTA19 Diesel). All parameters of the gas gensets and electrical parameters of the diesel gensets are incorporated. The PLCs communicate with the Reliance system over Ethernet.


The installed system has the capacity to control and monitor five more gensets in the future without the need of any additional hardware.


The Reliance SCADA system provides the monitoring and control of the following:


  • Graphics-oriented operator screens displaying important information obtained from different types of gensets along with remote control
  • Feeders' status and important electrical parameters
  • All parameters of the Cummins QSK60 Gas gensets
  • Electrical parameters of the Cummins KTA19 Diesel gensets
  • Real-time and historical trending of all the important parameters
  • Archiving of reports, alarms/events, and trends
