Publication number: 20240112073Abstract: One component of time domain protection in a power system is estimating the location of a fault. In an embodiment, a multi-objective problem is formulated that comprises a non-smoothness penalization function that drives the primary objective function for fault location estimation towards a solution that respects smoothness between the inputs and outputs of a machine-learning model. This technique improves the accuracy, blind zone, and speed of state-of-the-art techniques, in the context of time domain protection, as well as for other regression tasks. In an additional or alternative embodiment that is specific to time domain protection, the multi-objective problem may comprise a phasor-deviation penalization function that drives the primary objective function towards a solution that minimizes deviations in phasor values. The trained machine-learning model may be executed in a line protection system to determine whether or not to trip a circuit breaker of a power line.Type: ApplicationFiled: September 22, 2022Publication date: April 4, 2024Inventors: Jhelum CHAKRAVORTY, Pawel DAWIDOWSKI, Jan POLAND

Patent number: 10605229Abstract: The present invention is concerned with an operation of a wind farm with a plurality of wind turbines in view of a dynamic frequency response. According to the invention, dynamic frequency support and power production for all wind turbines in a wind farm are handled concurrently in a single optimization step and taking into account wake effects within the wind farm as well as optional wind forecast information. The dynamic frequency support capability of the entire wind farm is planned in advance according to grid requirements and power system condition changes. While existing methods de-load wind turbines with a static percentage in order to supply additional power when needed, the proposed method incorporates the dynamic frequency support into the optimal operation system of wind farm.Type: GrantFiled: November 17, 2017Date of Patent: March 31, 2020Assignee: ABB Schweiz AGInventors: Yan Zhang, Jan Poland, Adrian Vasile Timbus, Carsten Franke, Kedar Kulkarni, Silvia Mastellone

Patent number: 9285787Abstract: A model-based control of an industrial process using a merged MLD system model is provided for the estimation and subsequent control of the process. An optimization of an objective function is performed. The objective function includes a difference between an observed quantity and an output variable of a Mixed Logical Dynamic (MLD) system model of the process. The optimization is performed as a function of state variables of the MLD system model, over a number of time steps in the past, and subject to constraints defined by the MLD system model's dynamics. The optimizing values of the state variables are retained as estimated initial states for subsequent control of the process in a model-based manner including the same MLD system model. The single MLD system model is a combination or merger of individual MLD subsystem models representing the sub-processes of the process, and may be elaborated during a customization step.Type: GrantFiled: December 22, 2011Date of Patent: March 15, 2016Assignee: ABB RESEARCH LTDInventors: Alvarez Eduardo Gallestey, Jan Poland, Konrad Stadler, Sebastian Gaulocher, Hamed Foroush

Publication number: 20110208341Abstract: A control system for controlling an industrial process includes an indicator generator configured to determine at least one fuzzy logic based indicator from measured process variables. The control system also includes a state estimator configured to determine estimated physical process states based on the fuzzy indicator. For controlling the industrial process, the process controller is configured to calculate manipulated variables based on (i) defined set-points and (ii) a physical model of the process using the estimated physical process states. Combining a fuzzy logic indicator with a model based process controller provides robust indicators of the process states for controlling an industrial process in a real plant situation in which measured process variables may possibly contradict each other.Type: ApplicationFiled: March 18, 2011Publication date: August 25, 2011Applicant: ABB RESEARCH LTD.Inventors: Konrad STADLER, Eduardo Gallestey Alvarez, Jan Poland
