PLANT PERFORMANCE COMPUTING DEVICE

PURPOSE: To correct, store, diagnose, and predict plant performance computation data by reprocessing results after data correction and re-setting plant performance data in a computation result data base. CONSTITUTION: This device is equipped with a data correcting processing means 4 which takes data out of the computation result data base 11 when an event such as a data deficit occurs and corrects the data, a CRT device 6 which corrects the data, and a display processing means 5. The correction results of the data correction processing means 4 are stored in a correction result data base 7 and the reprocessing is performed by a performance data computation processing means 2 on the basis of the data set in the correction result data base 7 to reset the plant performance data in the computation result data base 11. Namely, the data correction processing means 4 takes the data out of the computation result data base 11, the data are corrected by manual input and saved in the correction result data base 7, and the plant performance data after the correction are stored in the computation result data base 11 by a performance data computation processing means 22.
