With the wide application of DCS in thermal power plants, its dominant position in the safe and stable operation of units is becoming more and more prominent. Due to the reliability of software and hardware of DCS equipment, the perfection and rationality of control logic, the maintenance and overhaul level of thermal personnel and many other factors, unit false tripping events still occur from time to time. Therefore, effective technical management and correct overhaul and maintenance to maintain the stable and reliable operation of thermal power unit DCs has increasingly become the focus of daily management and maintenance of thermal workers. Therefore, combined with the above case analysis, the author puts forward some preventive measures to improve the reliability of the control system for reference in maintenance:

● implement the whole process management for DCS equipment and maintenance, find defects as soon as possible and deal with them in time. Improve the DCS self diagnosis and fault alarm functions. The real-time monitoring of DCS operation status should not only monitor the status of the main controller, but also monitor the status of the main controller network.

● formulate a reasonable regular maintenance system, specify the contents, methods and cycles of inspection and maintenance in detail, analyze the inspection results and take targeted preventive measures. Since the trial implementation of this system, Zhenhai Power Plant has effectively controlled the occurrence of DCS faults.

● formulate DCS emergency plan and typical fault handling scheme to prevent DCS fault caused by improper maintenance.

● select high-quality spare parts, such as cooling fan and DP plug of main controller, and replace vulnerable parts regularly.

● remotely monitor the ambient temperature of the electronic room, access DCS display, and master the change of the ambient temperature of the electronic room in real time. The electronic room with central air conditioner shall also pay attention to the control of humidity. If necessary, an independent air conditioner or dehumidification device shall be installed.

● check the appearance of module circuit board during maintenance, which can play a good preventive effect.
