Method for managing subsystems of a process plant using a distributed control system

1. A method for managing a plurality of subsystems of a process plant by controlling process parameters of a process in the process plant, wherein each subsystem of the plurality of subsystems comprises at least one of a field device and a process equipment, wherein the process plant is controlled using a Distributed Control System (DCS) with a plurality of databases distributed within the process plant, wherein each database of the plurality of databases comprises information corresponding to at least one subsystem of the plurality of subsystems, wherein the information corresponding to the at least one subsystem of the plurality of subsystems is at least one of state information, technical specification information, and measurement information associated with the at least one of the field device and the process equipment of the at least one subsystem, the method comprising:

receiving a query of a predetermined type at a human machine interface of the DCS, wherein the query is associated with at least one of an operation and a health of a select subsystem of the plurality of subsystems, and wherein the predetermined type is at least one of predict, aggregate, fetch, classify, and regress;

identifying, at a server of the DCS, one or more databases comprising information corresponding to the select subsystem associated with the query, wherein the one or more databases are identified from the plurality of databases based on the query;

processing the query, at the server, based on the information corresponding to the select subsystem available on the one or more identified databases, wherein processing the query comprises: (i) identifying, from a database of the one or more identified databases comprising a plurality of models and model ensembles, at least one of a model and a model ensemble for processing the query, wherein the at least one of the model and the model ensemble is identified based on the predetermined type of the query, and wherein the at least one of the model and the model ensemble fits the information corresponding to the select subsystem; and (ii) adapting the identified at least one of the model and the model ensemble by utilizing the information corresponding to the select subsystem; and

utilizing the identified at least one of the model and the model ensemble in the DCS to control the operation of the select subsystem by controlling process parameters of the process based on said processing of the query.

2. The method of claim 1 , wherein adapting the identified at least one of the model and the model ensemble comprises utilizing at least one part of the information corresponding to the select subsystem for training the identified at least one of the model and the model ensemble and at least one other part of the information corresponding to the select subsystem for testing the identified at least one of the model and the model ensemble.

3. The method of claim 2 , wherein training comprises a step of evaluation, wherein a portion of the at least one part of the information corresponding to the select subsystem is reserved for the evaluation.

4. The method of claim 1 , wherein adapting the identified at least one of the model and the model ensemble comprises determining an error in application of the identified at least one of the model and the model ensemble based on the information corresponding to the select subsystem.

5. The method of claim 1 , wherein controlling the operation of the select subsystem comprises at least one of servicing the select subsystem and replacing at least one of the field device and the process equipment of the select subsystem.

6. The method of claim 1 , wherein the process plant is a substation.

7. The method of claim 1 , wherein the process plant comprises a substation.
