Patent number: 11929608Abstract: Systems and methods are described herein to accommodate different settings associated with an inverter-based electric power generator and an inverter-based electric power generator for electric power generation within an electric power delivery system. The electric power delivery system may provide electric power generated by a bulk electric system to the loads via distributed substations using a first operating frequency. Moreover, the distributed substations may include inverter-based electric power generators to supply the electric power demand of downstream loads in an islanded configuration. That said, the inverter-based electric power generators may supply the electric power using a second frequency that is higher than the first frequency. Protective systems, positioned downstream from the distributed substations, may use different settings associated with the bulk electric system or the inverter-based electric power generators based on detecting the frequency of the supplied electric power.Type: GrantFiled: June 10, 2022Date of Patent: March 12, 2024Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Scott M. Manson, Jorge Fernando Calero, Angelos Kokkinis

Patent number: 9941684Abstract: A quadrilateral distance module may be used to detect faults in an electrical power system. A resistive coverage of the quadrilateral distance module may be defined by an adaptive resistance blinder. Tilt of the adaptive reactance element and resistance blinders may be limited. When an angle between the sequence-component based, current polarizing quantity and the element loop current does not exceed a predetermined angle threshold, the sequence-component based polarizing quantity may be used. Otherwise, the element loop current may be used to limit the tilt. Fault detection may comprise comparing both the adaptive resistance blinders for forward and reverse load flow conditions to power system stimulus and detecting a fault when the stimulus satisfy either blinder.Type: GrantFiled: May 12, 2015Date of Patent: April 10, 2018Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Jorge Fernando Calero, Armando Guzman-Casillas

Patent number: 9257827Abstract: A quadrilateral distance module may be used to detect faults in an electrical power system. A resistive coverage of the quadrilateral distance module may be defined by an adaptive resistance blinder. The adaptive resistance blinder may be adapted to certain power system conditions, such as forward load flow and/or reverse load flow. A forward adaptive resistance blinder may be calculated in parallel with a reverse adaptive resistance blinder. The forward adaptive resistance blinder may use a polarizing quantity adapted for forward load flow conditions, and the reverse adaptive resistance blinder may use a polarizing quantity adapted for reverse load flow conditions. Fault detection may be performed by comparing both the forward and reverse adaptive resistance blinders to power system stimulus and detecting a fault when the stimulus satisfy either blinder.Type: GrantFiled: February 20, 2013Date of Patent: February 9, 2016Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Jorge Fernando Calero, Armando Guzman-Casillas, Gabriel Benmouyal
