Abstract:
1. A system for facilitating detection and identification of a transient operation from an abnormal operation of a process in a process plant, the system comprising: a data collection tool adapted to collect on-line process data from a process control system within the process plant, wherein the collected on-line process data comprises data representative of an operation of the process when the process is on-line and wherein the collected on-line process data is generated from a plurality of process variables of the process; a first analysis tool comprising a first multivariate statistical analysis engine adapted to generate a first representation of the operation of the process based on a first set of the collected on-line process data generated from a first set of the process variables of the process, wherein the first representation of the operation of the process is adapted to be executed to generate a first result; a second analysis tool comprising a second multivariate statistical analysis engine adapted to generate a second representation of the operation of the process based on the first result and based on a second set of the collected on-line process data generated from a second set of the process variables of the process, wherein the second representation of the operation of the process is adapted to be executed to generate a prediction of data generated from the second set of the process variables; and a monitoring tool adapted to analyze the prediction to detect whether one or more abnormal operations detected based on the first representation of the operation of the process comprises a transient operation of the process.
