PRIDICTION METHOD FOR MONITORING PERFORMANCE OF PLANT INSTRUMENTS

摘要

PURPOSE: A prediction method for monitoring performance of plant instruments is provided to improve the accuracy of estimated value by monitoring the signal of a measurement unit. CONSTITUTION: Measured data is arranged in matrix at each measurement unit(S100). The data of each measurement unit is normalized(S200). Whole data is displayed as a data sheet. The data sheet is divided into training data, optimizing data, and a test data(S300). The main component of each data is extracted(S400). An optimum constant of an SVR model is calculated(S500). A training model is generated at each measuring unit(S600). The predictive value of the training model at each measuring unit is calculated(S700).
