Operation Philosophy
- We have to boost Natural gas pressure from 3.5 Kg/cm to 21 Kg/mm to run the turbine.
- Local control Panel controls Waukesha Gas Engine and compressor.
- Waukesha Gas Engine is communicated by Modbus.
- Purge system is used to avoid spark at panel.
- To maintain pressure at the system PID controllers are used.
- All engine parameters and Gas flow meter parameters (Approx. 100 parameters ) shown at HMI and scada screen.
- Data logging for some important 90 parameters to track 1 sec data.
- We have to boost Natural gas pressure from 3.5 Kg/cm to 21 Kg/mm to run the turbine.
- If Gas pressure is down due to other panel trip, then PLC can take care Discharge pressure by increasing Engine speed from 900 rpm to 950 rpm.
