Patent number: 10983150Abstract: Various embodiments described in this disclosure pertain to methods and systems for detecting and evaluating oscillations in an electrical power grid. The oscillations can include one or more oscillatory conditions, which can occur in one or more of five predefined frequency bands. Each of the five predefined frequency bands is categorized at least in part, by oscillations that are originated by uniquely different sources. In one embodiment, an oscillation detector can be used to detect the oscillatory condition and determine a magnitude characteristic, a phase characteristic, and/or a damping characteristic of at least one oscillation frequency that contributes to the oscillatory condition.Type: GrantFiled: August 28, 2017Date of Patent: April 20, 2021Assignee: General Electric Technology GmbHInventors: Zhiying Zhang, Ilia Voloh, Mark Gerard Adamiak

Patent number: 10088516Abstract: Embodiments of the disclosure relate to detecting turn-to-turn faults in one or more windings of various objects. In one implementation, a fault detector uses a differential protection algorithm to detect a turn-to-turn fault in a winding of a three-phase shunt reactor. Various voltage and current measurements carried out upon the three-phase shunt reactor are used to calculate a difference value between a voltage-based parameter and a current-based parameter. The voltage-based parameter is indicative of a normalized negative voltage imbalance and the current-based parameter is indicative of a normalized negative current imbalance. A turn-to-turn winding fault is declared when the difference value is not equal to zero.Type: GrantFiled: February 10, 2016Date of Patent: October 2, 2018Assignee: General Electric CompanyInventors: Zhiying Zhang, Sarasij Das, Tarlochan Sidhu, Mohammad Reza Dadash Zadeh
