Patent number: 11843325Abstract: A method for operating a multi-level bridge power converter of an electrical power system connected to a power grid includes receiving, via a controller of the power converter, an indication of a transient event occurring in the power grid or the electrical power system. The power converter has a plurality of switching devices arranged in an active neutral point clamped topology. Accordingly, upon receiving the indication, the method includes activating a crowbar algorithm programmed in the controller of the power converter to bifurcate a current received by the power converter into a plurality of different current paths defined by the plurality of switching devices.Type: GrantFiled: August 24, 2020Date of Patent: December 12, 2023Assignee: General Electric CompanyInventors: Bacil Shaqqo, Fernando Arturo Ramirez Sanchez, Nathaniel Robert Michener, Steven Wade Sutherland

Publication number: 20230141934Abstract: A system and method are provided for controlling a power generating facility. Accordingly, the facility-level controller determines a reactive-power-delivery coefficient for each power generating asset of the power generating facility. The reactive-power-delivery coefficient includes at least one of a reactive-power-generation coefficient and a reactive-power-transmission coefficient. The reactive-power-delivery coefficient is indicative of an impact on the active power production capability of each of the power generating assets due to a change in an amount of reactive power delivered to a point of interconnect. Based at least in part on the reactive-power-delivery coefficient, the facility-level controller determines a portion of a demand signal to be satisfied by each of the power generating assets.Type: ApplicationFiled: March 3, 2020Publication date: May 11, 2023Inventors: James Gregory Rotbert, Alina Fatima Moosvi, Patrick Hammel Hart, Charles Joseph Kosuth, Bacil Shaqqo, Enno Ubben, Alev Akbulut

Patent number: 11545910Abstract: A power conversion assembly includes a power converter having a plurality of switching devices, a power source electrically coupled to the power converter, and a direct current (DC) filter circuit bridging the power converter and the power source. The DC filter circuit includes a DC link having a positive rail, a negative rail, and a capacitor bank. The capacitor bank includes a first set of capacitors being a first type of capacitors and a second set of capacitors being a different, second type of capacitors. Each capacitor in the first set of capacitors is positioned closer to a respective switching device of the plurality of switching devices than a corresponding capacitor of the second set of capacitors to minimize impedance between each capacitor in the first set of capacitors and the respective switching device such that a majority of ripple current from the plurality of switching devices passes through the first set of capacitors.Type: GrantFiled: August 28, 2020Date of Patent: January 3, 2023Assignee: General Electric Renovables Espana, S.L.Inventors: Rajesh Bhupathi, Robert Gregory Wagoner, Zane Taylor Miller, Fernando Arturo Ramirez Sanchez, Bacil Shaqqo, Joseph Kiran Banda

Patent number: 11394324Abstract: A method for operating a multi-level bridge power converter of an electrical power system includes connecting a plurality of phases of the power converter to a common terminal at a DC side of the power converter so as to effectively equate the plurality of phases at a common electrical potential. The method may also include monitoring, via a controller, a plurality of devices of the power converter for faults. Upon detection of a fault in one or more of the plurality of devices, the method includes activating, via the controller, one or more protection devices of a crowbar of the power converter to prevent additional faults from occurring in remaining devices of the plurality of devices by diverting energy away from the remaining devices of the plurality of devices.Type: GrantFiled: December 17, 2019Date of Patent: July 19, 2022Assignee: General Electric CompanyInventors: Bacil Shaqqo, Fernando Arturo Ramirez Sanchez, Steven Wade Sutherland

Patent number: 11258387Abstract: A method for controlling a three-level back-to-back voltage source power conversion assembly includes receiving an indication of a DC or AC unbalance occurring in voltage of a DC link. The power conversion assembly has a first power converter coupled to a second power converter via the DC link. In response to receiving the indication, the method includes activating a balancing algorithm that includes determining a deviation of a midpoint voltage of the DC link as a function of a total voltage of the DC link, calculating a voltage compensation needed for pulse-width modulation signals of the power conversion assembly based on the deviation, and coordinating common mode voltage injection from each of the power converters independently at a neutral point of the power conversion assembly based on the voltage compensation, thereby minimizing the at least one of the DC unbalance or the AC unbalance at any given operating condition.Type: GrantFiled: October 30, 2020Date of Patent: February 22, 2022Assignee: General Electric Renovables Espana, S.L.Inventors: Robert Gregory Wagoner, Joseph Kiran Banda, Kapil Jha, Fernando Arturo Ramirez Sanchez, Bacil Shaqqo, Hridya Ittamveettil
