PURPOSE:To obtain an effective plant operation supporting system, by dividing a whole plant into hierarchies by function and determining plant shifting operations at the time of abnormality in accordance with diagnosed results at every hierarchized subsystem. CONSTITUTION:Hierarchized subsystems can be considered as one tree structure. Subsystems S41, S33, S23, S13, and S0 are considered that they are on one route and the current operating capacity and latent operating capacity of each subsystem excluding the highest-rank system S0 are successively found. If, for example, the trip of a turbine driving water pump A is S41, the subsystem related to the turbine driving water pump A is S33, a water supplying system is S23, and the subsystem related to the water supply to a reactor is S13 and when the turbine driving water pump A trips, the flag of S41 is established and the route S41 S33 S23 S13 S0 is diagnosed. Then the operating capacities of S11-S13 which are one level lower than the S0 are found about all routes which become objects of diagnoses and operations for successively changing operating capacities to a shifting target are performed. |
