Description

Description:

Most generator sets use the DEH control system as the main control system for steam turbines, which is characterized by fast response, high reliability, and long-term safe and stable operation. The DEH control system can not only adjust the speed and power of the steam turbine, but also automatically increase speed, connect to the grid, increase or decrease load according to the stress and other auxiliary conditions of the steam turbine under different working conditions. It can also patrol, monitor, alarm, record, and recall the operating parameters of the steam turbine, generator unit, and main and auxiliary equipment.

DEH system failures caused by power failures often occur, especially after the CPU card PCA-6740 has been used for a long time, the lifespan of electronic components expires, and the failure rate of power modules is extremely high. The measures to be taken to prevent power module failures include selecting high-quality CPU cards, configuring cabinets reasonably, ensuring high power redundancy, regularly checking the output voltage of the power supply, checking the power circuit during maintenance to ensure there are no wiring problems, establishing management records for the power supply, managing the lifespan of the power supply, arranging replacement of power supplies that have expired, and not waiting for power supply failures before replacement.
