Patent number: 11692866Abstract: A computer-implemented method and system for Condition Monitoring (CM) for rotating machines. The method and system include continuously receiving samples of the envelope of physical quantity data such as speed, vibration, or current, updating in real-time accumulator variables, computing in real-time spectral features based on the accumulator variables and supplemental variables, and determining a condition based on the real-time spectral features. The spectral features, exemplary as amplitudes at specific frequencies, are computed in real-time by a Goertzel Algorithm. The totality of the accumulator variables is sufficient to determine the condition of the rotating machine and the supplemental variables are temporarily needed for computing the spectral features. The one or more supplemental variables, such as memory addresses, are not based on the received samples of the input data.Type: GrantFiled: October 7, 2020Date of Patent: July 4, 2023Assignee: Siemens AktiengesellschaftInventor: Jürgen Zettner

Publication number: 20220373589Abstract: A method for evaluating partial discharge signals. Partial discharge signals are captured, at only one point or at a plurality of points, near insulation of the electrical outer conductors of a multi-phase alternating current. The multi-phase alternating current, flowing in respective outer conductors, has fixed phase shifts relative to each other. Partial discharge signals are superposed on each other. At least one characteristic variable of the partial discharge signals is defined. Each partial discharge signal is assigned a phase position. A characteristic variable value of each characteristic variable is determined. Each partial discharge signal is assigned a number tuple from each characteristic variable value of the partial discharge signal and from the phase position. Clusters of the partial discharge signals in a multi-dimensional space with points formed by the number tuples are determined. A partial discharge activity is determined for each outer conductor from the determined clusters.Type: ApplicationFiled: August 17, 2020Publication date: November 24, 2022Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Martin Meyer, DIRK SCHEIBNER, JÜRGEN ZETTNER

Patent number: 11060933Abstract: In a method for determining loading of a bearing supporting a rotor of an electrical machine, the rotational speed and angular acceleration of the rotor is determined, matrix elements of a matrix are assigned to respective ranges of the angular acceleration and to respective ranges of the rotational speed, when the electrical machine is operated in a respective range of the angular acceleration and the rotational speed corresponding to the respective matrix element for a predefined time unit, an elementary variable, for example a value of 1, is added to the respective matrix element, and the loading of the bearing is determined as a weighted sum of the matrix elements. Thus, the matrix forms a representation of the operating time of the bearing and of the service life over time in relation to the rotational speeds and angular accelerations. The loading can be shown on a display.Type: GrantFiled: April 26, 2019Date of Patent: July 13, 2021Assignee: Siemens AktiengesellschaftInventors: Ulf Bormann, Hans-Henning Klos, Jürgen Schimmer, Jürgen Zettner, Dirk Scheibner

Patent number: 10890466Abstract: A rotating element is mounted in a base body for rotation about an axis of rotation. An excitation circuit generates an excitation signal. A divider circuit divides the excitation signal into a base signal supplied to an evaluation circuit and into an outgoing signal supplied to a transceiving antenna. A waveguide circulates in an annular manner about the axis of rotation. The rotating element comprises a termination element protruding into the waveguide and has a reflective side. The transceiving antenna emits an electromagnetic signal into the waveguide propagating in two directions which is reflected from the reflective side and returned to and received by the transceiving antenna which generates in response a receiving signal supplied to the evaluation circuit which determines a position of rotation of the rotating element in relation to a reference position of rotation by evaluating the base signal and receiving signal in a resolution region.Type: GrantFiled: October 24, 2018Date of Patent: January 12, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Martin Meyer, Jürgen Zettner
