Patent number: 11105190Abstract: The disclosed embodiments include a power and data delivery system for downhole gauges of a well. The power and data delivery system includes a three-phase power supply coupled to a power cable to supply power to a downhole motor positioned along a wellbore. Additionally, the power cable transmits power and data signals. The power and data delivery system also includes a downhole gauge coupled to the downhole motor, and the downhole gauge transmits downhole data signals along the power cable to a gauge surface panel. Further, the power and data delivery system includes at least one gauge positioned remotely from the downhole gauge and coupled to the power cable. The at least one gauge also transmits gauge data signals along the power cable to the gauge surface panel.Type: GrantFiled: October 19, 2016Date of Patent: August 31, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Stewart Darold Reed, Srilatha Boyanapally

Patent number: 9828850Abstract: An electrically powered artificial lift system includes a tubular for conveying a wellbore fluid upward and a downhole pump that urges the wellbore fluid into the tubular. A power cable conveys a three-phase power signal to the pump motor on three conductors. One of the three conductors is coupled to an internal node of a high-to-low voltage (HLV) source coupler via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. A similar downhole coupler couples a wye point of the motor to a downhole sensor assembly to supply the sensor power signal and to receive the telemetry signal.Type: GrantFiled: April 28, 2015Date of Patent: November 28, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Srilatha Boyanapally, Aram Shihab Khaleel Almuhana, Sudhir Kumar Gupta

Patent number: 9109517Abstract: A method of monitoring health of a mechanical drive train is provided. The method includes obtaining voltage and current signals from at least one phase of an electrical machine coupled with the mechanical drive train. The method also includes representing the electrical machine having a non-sinusoidal flux distribution as a combination of a plurality of harmonic order sinusoidally distributed virtual electrical machines based on the obtained voltage and current signals. The method further includes determining a torque profile associated with one or more combinations of the sinusoidally distributed virtual electrical machines. Finally, the method includes detecting the presence of an anomaly in the mechanical drive train based on the torque profile or spectrum.Type: GrantFiled: March 14, 2011Date of Patent: August 18, 2015Assignee: General Electric CompanyInventors: Arijit Banerjee, Rupam Mukherjee, Arvind Kumar Tiwari, Somakumar Ramachandrapanicker, Srilatha Boyanapally, Paul Lloyd Flynn, Ajith Kuttannair Kumar

Patent number: 9050894Abstract: A method for a vehicle having plural electric motors includes generating motor electrical signatures for the motors. The motor electrical signatures represent one or more characteristics of electrical energy that is supplied to the motors. The method also includes identifying one or more fault measures of each of the motor electrical signatures. The fault measures are indicative of mechanical characteristics of the motors. The method further includes comparing the one or more fault measures of each motor with the one or more fault measures of the other motors in the same vehicle and predicting an impending mechanical failure of one or more of the motors based on comparing the fault measures of the motors.Type: GrantFiled: July 6, 2011Date of Patent: June 9, 2015Assignee: General Electric CompanyInventors: Arijit Banerjee, Rupam Mukherjee, Ajith Kumar, Somakumar Ramachandrapanicker, Srilatha Boyanapally, Mohan Kumar Katta

Patent number: 8914171Abstract: A route examining system includes first and second application devices, a control unit, first and second detection units, and an identification unit. The first and second application devices are disposed onboard a vehicle traveling along a route having conductive tracks. The control unit controls injection of a first examination signal into the conductive tracks via the first application device and injection of a second examination signal into the conductive tracks via the second application device. The first and second detection units monitor electrical characteristics of the route in response to the first and second examination signals being injected into the conductive tracks. The identification unit examines the electrical characteristics of the conductive tracks in order to determine whether a section of the route is potentially damaged based on the electrical characteristics.Type: GrantFiled: September 3, 2013Date of Patent: December 16, 2014Assignee: General Electric CompanyInventors: Joseph Forrest Noffsinger, Ajith Kuttannair Kumar, Yuri Alexeyevich Plotnikov, Jeffrey Michael Fries, Srilatha Boyanapally, Steven Joseph Ehret

Patent number: 8803461Abstract: A method, system and computer program product for monitoring health of a synchronous machine is provided. The method includes receiving a plurality of phase voltage values and a plurality of phase current values. The method then computes a negative sequence voltage (Vn) based on the plurality of phase voltage values. The method also computes one or more operating parameters based on at least one of the plurality of phase voltage values and the plurality of phase current values. The method retrieves from a data store, one or more known Vn based on the one or more operating parameters. The method then computes a machine health indicator based on the computed Vn and the one or more known Vn, and raises an alarm based on the machine health indicator.Type: GrantFiled: December 22, 2010Date of Patent: August 12, 2014Inventors: Arvind Kumar Tiwari, Arijit Banerjee, Hao Huang, Xiaochuan Jia, Srilatha Boyanapally, Rupam Mukherjee
