Patent number: 11656589Abstract: Various embodiments of the present technology generally relate to power topology discovery in industrial environments. More specifically, some embodiments relate to automatic power topology discovery for factories based on device data that is already recorded for other purposes. Systems and methods described herein may be used to generate an accurate electrical network topology by collecting power data from power devices that may provide real-time or recorded measurements, detecting power change events, and matching power change signatures over power events for the devices in order to calculate the likelihoods of possible topology assumptions. Power change event data is used to recursively update topology probabilities using the Bayesian formula until a system topology can be produced with satisfactory confidence.Type: GrantFiled: September 9, 2020Date of Patent: May 23, 2023Assignee: Rockwell Automation Technologies, Inc.Inventors: Xiaolong Zhang, Benfeng Tang, Linglai Li, David B. Berman, Phillip R. Bush, Steven T. Haensgen, Michael L. Gasperi, Sean C. Schmelzer, Alex Nicoll

Patent number: 7671606Abstract: A technique is disclosed for determining capacitive, inductive, and resistive components of power line impedance via a portable line impedance measurement system. The measurement system includes a circuit that switches a burden resistor between power line conductors to cause a droop in a voltage waveform. The voltage waveform is sampled prior to inclusion of the resistor in the circuit, as well as after to identify the droop. The short circuit between the power lines is then removed by opening the circuit and a first effective capacitance in the test circuitry causes a resonant ring due to the inductive component of the power line impedance. The process is repeated a second time with a second effective load capacitance enabled in the test circuitry to cause a second resonant ring. Based upon the frequency of the rings and the voltage measurements, the individual impedance components of power line impedance can be computed.Type: GrantFiled: April 30, 2007Date of Patent: March 2, 2010Assignee: Rockwell Automation Technologies, Inc.Inventor: Michael L.
