Patent number: 10162015Abstract: Embodiments of the disclosure relate to systems and methods for determining a fault location in a three-phase series-compensated power transmission line system by using symmetrical components-based formulas that describe various voltage and current relationships. The voltage and current relationships can be derived using a synchronous measurement procedure that is concurrently executed at a sending end and a receiving end of the first series-compensated power transmission line system. Furthermore, determining the fault location in accordance with certain embodiments of the disclosure can eliminate one or more of a need to calculate an impedance value of any of the series capacitors or the series capacitor protection elements that are a part of the three-phase series-compensated power transmission line system, a need to monitor any of the series capacitor protection elements, and a need to measure a voltage drop across any of the series capacitors.Type: GrantFiled: March 29, 2016Date of Patent: December 25, 2018Assignee: General Electric CompanyInventors: Zhihan Xu, Tirath Bains, Tarlochan Sidhu, Mohammad Reza Dadash Zadeh

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

Patent number: 9026259Abstract: A microgrid including a renewable power source is optimized by treating the renewable source as operating in an isochronous mode, and by decomposing the optimization process. A renewable capability is defined for the renewable source to enable treatment of the renewable source as operating in an isochronous mode. The renewable capability may be based on a power rating of the renewable source. An objective function of the microgrid optimization problem may then be optimized while treating the renewable source as operating in an isochronous mode. A penalty factor may be applied to avoid power shortage.Type: GrantFiled: January 25, 2012Date of Patent: May 5, 2015Assignee: General Electric CompanyInventors: Mohammad Reza Dadash Zadeh, Amirhossein Hajimiragha, Michael Joseph Krok

Patent number: 8795481Abstract: A power generation system including an electrolyzer may be optimized taking non-linear operational constraints into account with lower processing requirements than current solutions in real time. A pre-processing module assesses non-linear operational constraints in a low-overhead manner and passes results to an optimization module. The optimization module determines an operating power value constrained in accordance with results from the pre-processing module. A post-processing module uses results from the pre-processing and optimization modules to assemble instructions to control the electrolyzer. As a result, optimization may be performed in real time.Type: GrantFiled: January 3, 2012Date of Patent: August 5, 2014Assignee: General Electric CompanyInventors: Mohammad Reza Dadash Zadeh, Amirhossein Hajimiragha, Michael Joseph Krok
