The extracted noise is correlated with a noise extracted from a plurality of reference signals using an AI based data analysis technique. Further, the process control system identifies deviations in the one or more parameters. The process control system detects the faults the plurality of measuring instruments or the process equipment using the correlated noises and the identified deviations of the one or more parameters.Type: ApplicationFiled: April 20, 2020Publication date: June 30, 2022Applicant: ABB Schweiz AGInventors: Shrikant Bhat, Rahul Kumar-Vij

Publication number: 20220066425Abstract: The present invention relates to a method and a system for controlling a process of a process plant. Hie system is configured to control a process in the process plant by recommending control operations and perform the control operations. The system obtains the control operations and detects availability of control room operators using historical data related to actions performed by the control room operators, sensory parameters of the control room operators and a status associated with the process. The system provides queries related to the control operations, the plant parameters, status of the process to the control room operators upon detecting the availability. Hie queries are validated by the control room operators. The system thereafter autonomously controls tire control room based on the validated data.Type: ApplicationFiled: December 26, 2019Publication date: March 3, 2022Inventor: Shrikant BHAT

Patent number: 10591875Abstract: A method and system are disclosed for optimizing load scheduling for a power plant having one or more power generator units. An exemplary method and corresponding system can involve detecting an event indicative of a need for adapting one or more constraints for an objective function used in load scheduling. On such detection, the objective function is analysed to determine adaptive constraint values for the one or more constraints for optimally solving the objective function. These adaptive constraint values can be used to solve the objective function and the solution of the objective function with the one or more adapted constraint values can be used to operate the one or more power generation units of the power plant.Type: GrantFiled: July 2, 2012Date of Patent: March 17, 2020Assignee: ABB Schweiz AGInventors: Mohan Kumar Shanmugam, Senthil Kumar Sundaram, Gopinath Selvaraj, Shrikant Bhat

Patent number: 10503155Abstract: The present invention discloses a method for controlling a process using a plurality of regulatory controllers (160) connected to a remote supervisory controller (120) over a communication link (155) and to a local supervisory controller (130) over a process bus (170). The remote supervisory controller (120) controls the regulatory controllers (160) over the communication link (155) with the use of a remote process model. During operation of the plant a local process model is configured in the local supervisory controller (130) with control data send on the communication link (155). Upon failure of the communication link (155) the local supervisory controller (130) takes over the control through the process bus (170), acting as a redundant or a backup controller.Type: GrantFiled: June 25, 2015Date of Patent: December 10, 2019Assignee: ABB Schweiz AGInventors: Shrikant Bhat, Michael Lundh

Patent number: 10392747Abstract: A method is disclosed for optimization of continuous digestion process. Exemplary embodiments can control a delignification process in a continuous pulp digester in an optimal way for different pulp grades taking into account process disturbances and model uncertainties. This can be achieved by customizing a generic mathematical model for a continuous digestion process which runs through a software application on a dedicated electronic device. The model can be updated periodically based on on-line information, and used with a plant optimization component involving multi-objective optimization to evaluate optimal set points for the controllers. A system is also disclosed for optimizing control of a continuous pulp digester.Type: GrantFiled: August 15, 2011Date of Patent: August 27, 2019Assignee: ABB Schweiz AGInventors: Shrikant Bhat, Babji Buddhi Srinivasa, Prasanna Pathath

Publication number: 20140207415Abstract: An exemplary energy auditing system and a method for obtaining a validated performance solution for a plant are provided. An exemplary system and method includes at least one processor that obtains plant data for calculating one or more performance metrics. An initial benchmark is generated using performance metrics, a tunable process model and an optimizer. A rules engine is used for applying rules based on a dynamic input on the initial benchmark and current performance metrics, and for generating an output. A decision analysis module is used for validating if the output meets the specifications of the dynamic input using a what-if analysis. If the specifications are met, then the output is provided as a validated performance solution. If the specifications are not met, then the benchmark is evolved and the validating steps are repeated.Type: ApplicationFiled: March 24, 2014Publication date: July 24, 2014Applicant: ABB TECHNOLOGY LTDInventors: Naveen BHUTANI, Srinivas Mekapati, Senthilmurugan Subbiah, Shrikant Bhat
