Abstract: A method is proposed for the monitoring of a plant having a plurality of sub-systems which is operable at variable working points. Respective measured values are detected for a fixed set of process parameters (B, U, S1, . . . , SN) at pre-settable time intervals during the operation of the plant (1). The measured values detected in a learning phase for different working points are used to prepare models (M1, M2, . . . , MN) for the operating characteristics of the sub-systems (11, 12, . . . , 1N). At least one monitoring parameter (Ri, Rik), which is independent of the respective current working point, is determined at pre-settable time intervals in an operating phase using the models (M1, M2, . . . , MN) and the time-dependent course of the monitoring parameter (Ri, Rik) is used for the monitoring of the plant (1).

Abstract: In a method for monitoring plants with mechanical components, measured values (xiT; xiu) are determined at predeterminable time intervals for a fixed set of parameters (xi). The measured values (xiT) which are determined for various working points during a modelling phase are used for the generation of a model for the operating behavior of the components. With the help of the model for the operating behavior at least one monitoring value (r; snu) is derived at predeterminable time intervals which is independent of the respective current working point. The temporal behavior of the monitoring value (r; snu) is used for estimating the wear in the components and/or for the detection of operating disturbances.
