Fault analysis on desulfurization DCS signal interference in a thermal power plant

Abstract

Abstract:

The desulfurization DCS of a thermal power plant suffers from multiple signal interference,which seriously affects the stable operation of the unit.Six signal fluctuation situations are introduced and troubleshooting is made from interference sources,propagation paths and sensitive bodies.Rectification measures such as renovating the road light power supply circuit, standardizing the DCS grounding,cleaning the cable trench are proposed.After the rectification,the system is more stable and there is no signal interference in it.
