Plant performance evaluation system and plant performance evaluation method

摘要

Problem to be solved: to provide a plant performance evaluation system and a plant performance evaluation method capable of evaluating plant performance without depending on the technical power and labor of the person in charge.Solution: This is a plant performance evaluation system which is used for a plant equipped with various kinds of sensors and various sensors for measuring the state of these devices.This plant performance evaluation systemWe investigate the relationship between sensors using sensor values sg1-sg3.The model of the plant was created from these relations.After thatThe measured values of each sensor at the time of the model were createdFrom the measured values received from the respective sensors for a given periodEstimated values areBased on the modelThe calculated values are compared with the measured values received from the respective sensors for a predetermined period.Compare the resultsAn analysis evaluating apparatus 40 as a result of evaluation of the plant is provided.Diagram
