Embodiment
[0035] At present, power plants implement centralized control of boilers, steam turbines and generators, and use distributed control system (DCS) to monitor and control production. For units with a single capacity of 300MW, DCS has more than 40 interfaces, and about 1,000 parameters need to be monitored. Parameter importance, grading the parameters:
[0036] 1. Category A: If the parameter exceeds the limit, catastrophic consequences will occur, and strict monitoring is required, such as main steam pressure, steam turbine speed, boiler drum water level, etc. Set a type A timer on the type A parameter measuring point interface of the DCS interface. The time interval between checking the parameter twice is not more than 5 minutes. When checking the parameter, the timer is cleared at the same time.
[0037] 2. Class B: If the parameter exceeds the limit, it will cause equipment damage, cause the unit to trip, reduce output, etc., such as the bearing temperature, vibration, heater...
