Online fault localization in industrial processes without utilizing a dynamic system model

A method for localizing faults in an industrial process, the industrial process comprising an industrial plant including a plurality of components, the method comprising:

• receiving 300 structural plant data 30 corresponding to the industrial plant;
• generating 310 a structured model of the process from the structural plant data 30;
• receiving 315 sensor data 20 from sensors measuring characteristics of the plurality of components;
• identifying parameters of the structured model from the received sensor data and storing the parameters;
• detecting faults during operation of the industrial plant utilizing the identified parameters and detecting changes in the parameters by comparing current parameters to stored parameters;
• and
• displaying 330 fault information via a display 566 to an operator 40.
