Publication number: 20240128752Abstract: A system for dynamic rating of a power grid may include a plurality of terminal units, and a controller. The terminal units may detect a voltage phasor and a current phasor at nodes of the power grid. The controller may, based on the voltage phasors and the current phasors of the plurality of nodes, determine a dynamic thermal stability power rating for each line, a dynamic angular stability power rating for each node, and a dynamic voltage stability power rating for each node. The controller may, based on the dynamic thermal stability power rating, the dynamic angular stability power rating, and the dynamic voltage stability power rating, determine a dynamic system rating for the power grid. The controller may control the power grid in response to the dynamic system rating.Type: ApplicationFiled: October 11, 2022Publication date: April 18, 2024Applicant: General Electric Technology GmbHInventors: Hengxu HA, Sankara Subramanian Srigopalakrishnamurthi, Mitalkumar KANABAR, Claudia COSOREANU, Rajagopal Kommu

Publication number: 20230300170Abstract: Systems and methods for power system switching element (PSSE) anomaly detection are disclosed. An example PSSE anomaly detection unit may include a power system switching element position estimator (PSSEPE) and a comparison unit. The PSSEPE may be configured to receive a set of measurements and a set of control commands associated with a PSSE, calculate an anomaly confidence score based on the set of measurements and the set of control commands, and estimate a calculated PSSE position based on the set of measurements and the set of control commands. The comparison unit may be configured to receive the calculated PSSE position from the PSSEPE, receive the set of measurements and the set of control commands from the PSSEPE, receive a reported PSSE position associated with the PSSE, and determine a PSSE anomaly decision based on a difference between the reported PSSE position and the calculated PSSE position.Type: ApplicationFiled: March 16, 2022Publication date: September 21, 2023Applicant: General Electric Technology GmbHInventors: Masoud ABBASZADEH, Mitalkumar KANABAR, Subhrajit ROYCHOWDHURY, Pubudu Eroshan WEERATHUNGA, Balakrishna PAMULAPARTHY

Patent number: 11733301Abstract: Systems and methods are disclosed for voltage-less electrical signature analysis for fault protection. The systems and methods described herein may involve determining voltage values for a motor (which may then be used to estimate a speed of the motor) when complete voltage measurements may not be available, or may only be temporarily available. More specifically, the systems and methods described herein may address three scenarios, which may include at least: (1) when only a single phase voltage input is available for a three-phase motor, (2) when no voltage input is available, or (3) when a voltage input is only available for a limited period of time (for example, during a learning phase of the motor).Type: GrantFiled: June 25, 2021Date of Patent: August 22, 2023Assignee: General Electric Technology GmbHInventors: Balakrishna Pamulaparthy, Mitalkumar Kanabar, Akilezkrishnamurthy Arthanari

Publication number: 20230221693Abstract: Systems and methods are disclosed for asset health assessment and fleet management. An example method may include classifying a first power system asset into a first sub-system and a second sub-system. The example method may also include measuring, by a processor of a protection relay and from a first power system asset, electrical, thermal, and/or mechanical data associated with the first power system asset. The example method may also include identifying a first fault feature for the first sub-system, wherein the first fault feature is influenced by load oscillations in the first power system asset. The example method may also include comparing the first fault feature to a second fault feature of a third sub-system in a second power system asset, wherein the second fault feature is the same as the first fault feature, and wherein the second fault feature is not associated with load oscillations.Type: ApplicationFiled: February 7, 2022Publication date: July 13, 2023Applicant: General Electric Technology GmbHInventors: Balakrishna PAMULAPARTHY, Mitalkumar KANABAR, Austin BYRNE, Umar Naseem KHAN

Patent number: 11639966Abstract: Systems, methods, and computer-readable media are disclosed for enhanced electrical signature analysis (ESA) for fault detection in electrical machines. The enhanced ESA uses an algorithm that is able to adaptively learn the behavior of a particular electrical machine and automatically establish fault thresholds for the electrical machine without requiring manual inputs from an operator. The particular algorithm described herein to accomplish this may use machine learning that may be used to model the behavior of the electrical machine in real-time and based on any properties specific to the electrical machine.Type: GrantFiled: March 15, 2021Date of Patent: May 2, 2023Assignee: General Electric Technology GmbHInventors: Balakrishna Pamulaparthy, Mitalkumar Kanabar, Akilezkrishnamurthy Arthanari

Patent number: 11424613Abstract: The technology described herein is generally directed towards a system for power transmission system protection and fault location, such as implemented in a deployable device at one or more junction points of a power transmission system. Aspects of the described technology can be directed to analyzing a traveling wave corresponding to a fault on a power transmission system. Example aspects can comprise receiving data representing current and voltage components of a traveling wave, maintaining the data in storage for fault location determination of the fault, transforming the data via a wavelet transform, into wavelet transform results and using the wavelet transform results for protection of the power transmission system.Type: GrantFiled: March 5, 2019Date of Patent: August 23, 2022Assignee: General Electric Technology GmbhInventors: Hengxu Ha, Mitalkumar Kanabar, Adriano Oliveira Pires, Elias Bencz, Lucas Barcelos de Oliveira

Patent number: 10928814Abstract: This disclosure relates to systems and methods for performing an autonomous procedure for monitoring and diagnostics of a machine using electrical signature analysis. In one embodiment of the disclosure, a method includes providing electrical data of an electrical rotating machine associated with at least one fault frequency. While in a learning mode, the method includes converting the electrical data from a time domain to a frequency domain to obtain baseline data. While in an operational mode, the method includes converting the electrical data from the time domain to the frequency domain to obtain monitoring data. The method further includes determining, based at least on the monitoring data, a ratio value at the fault frequency, determining a rate of change of the ratio value at the fault frequency, and, optionally, issuing, based on the rate of change, an alarm concerning at least one event of the electrical rotating machine.Type: GrantFiled: April 17, 2017Date of Patent: February 23, 2021Assignee: General Electric Technology GmbHInventors: Prabhakar Neti, Sudhanshu Mishra, Balamourougan Vinayagam, Mitalkumar Kanabar, Balakrishna Pamulaparthy, Vijayasarathi Muthukrishnan
