Power reduced due to scr system fault

Many thermal power plants use selective catalytic reduction (SCR) systems to complete flue gas denitration. The system has the characteristics of large inertia, large delay and nonlinearity.

If they are free from defect, test the VSD. One way to do this is to power down the drive (making sure any residual DC voltage bleeds off before accessing the terminals), disconnect the motor leads from the drive, turn the drive back on, and ramp the drive to full speed. If the drive faults out it must be repaired or replaced.The closed loop system will also reduce wastage. To safeguard the system even further, a back-pressure sensor is put before the SCR system. Monitoring the back pressure before the SCR will monitor the overall system effectiveness. If pipework has become damaged or has been removed (due to theft) and there is insufficient back pressure, the ...Hence, SCR catalyst in a DOC+DPF+SCR system will be aging faster than that in only a SCR system.

After a DPF service regen, the SCR system is purged of excessive DEF. It is easier to evaluate if an SCR brick is compromised right after a service regen because it eliminates the extra DEF that the system was exposed to. 6. The SCR system can also store NOx in cold temperatures (extended idle).The next morning I wake up, start the engine, lo and behold there is an SCR system fault message. I call my Driver Leader and she says to go ahead to my pick-up location and do a breakdown macro when I arrive. I do so. Upon arrival it goes to a full de-power limp home mode.
