Patent number: 11409264Abstract: Some embodiments include a server system including a first logic module executable by a processor for receiving a data communication from an industrial control system coupled to a communications network. In some embodiments, the data communication comprises data or data streams associated with the industrial process. The program logic of the first logic module includes a model configured to receive a variable and iterate and converge an optimization problem to an optimization solution to a first level of optimization based at least in part on the variable and the data or data streams. A second logic module executable by the processor is operatively data-linked to the first logic module and utilizes a model to iteratively process data values of the optimization solution to a second level of optimization with an increased level of optimization over the first level of optimization.Type: GrantFiled: July 12, 2019Date of Patent: August 9, 2022Assignee: AVEVA Software, LLCInventors: Rajkumar Vedam, Sreenivas Rao Bukka, Detong Zhang, Purt Tanartkit

Patent number: 5818208Abstract: Voltage flicker is a power quality problem in power distribution circuits which is caused by the operation of fluctuating loads such as AC and DC electric arc furnaces, spot welders, starting of large ac motors, and the like. Converters based on Voltage Source technology (VSC) connected in shunt close to the fluctuating load are found to have the capability of reducing the voltage flicker level. Flicker control systems responsive to the active and reactive power components are used to exploit the capabilities of VSC in accordance with the invention. The flicker control systems reduce the voltage flicker observed at the point of common coupling by adapting, e.g., H-infinity, Linear Quadratic Gaussian, Minimum Variance Control, and self-tuning design methods for flicker control in power systems having fixed or self-tuning flicker controller parameters.Type: GrantFiled: December 19, 1996Date of Patent: October 6, 1998Assignee: ABB Power T&D Company Inc.Inventors: Hisham A.
