On-line Analysis System Of The Operation State Of Each Heater In Steam Unit

The work of on-line analysis system of the operation state of each heater in steam unit include: (1) compile data collection procedure with DCS system; (2) consummate heat economy analysis model of energetic system; (3) base heater fault diagnosis model: (4) develop online analysis system of the operation state of each heater in steam unit. By study, the production include: (1) the educing of general matrix formula when working medium with heat passes through the heat system and acts; (2) the educing of equivalent model about heater exergy analysis; (3) the choosing of calculation program of the goal value of the end difference of heater; (4) the suitable feature parameters are selected, the method of fault vague pattern recognition to differentiate and fault tree analysis and contradictory fault detection mainly are considered connectively and reasonably, as a result the theory of heater fault diagnosis was educed; (5) the development of online analysis system of the operation state of each heater in steam unit.
