METHOD FOR PROCESS STATE CLASSIFICATION OF A BIOGAS DIGESTER BASED ON PROCESS VARIABLES OF A BIOGAS PLANT

Original (Chinese)

Method for classifying a process state of a biogas digester based on at least one process variable of a biogas plant, the method comprising the steps of: a) Measuring a set of values of at least one process variable of a biogas digester; b) Providing a model that monitors the stability of the biogas digester, wherein the model is trained with a dataset comprising historical data of the digester of the biogas plant, the historical data including the at least one process variable; c) Implementing the measured set of values of the process variable of step a) into the model of step b) with the aid of a data processing unit; d) Identifying whether an outlier occurs in the set of values of step a), after implementing the at least one process variable into the model; e) Classifying a process state indicative of the stability of the biogas digester based on the presence or absence of the identified outlier of step d) with the aid of the data processing unit.
