Abstract: A power system grid is decomposed into several parts and decomposed state estimation steps are executed separately, on each part, using coordinated feedback regarding a boundary state. The achieved solution is the same that would be achieved with a simultaneous state estimation approach. With the disclosed approach, the state estimation problem can be distributed among decomposed estimation operations for each subsystem and a coordinating operation that yields the complete state estimate. The approach is particularly suited for estimating the state of power systems that are naturally decomposed into separate subsystems, such as separate AC and HVDC systems, and/or into separate transmission and distribution systems.

Abstract: The present disclosure relates to a magnetic-inductive flow meter having a measuring tube on which there is fitted a magnetic unit for generating a magnetic field, which is aligned substantially perpendicular to a flow direction of an electrically conductive measuring medium flowing through the measuring tube and whose measurement voltage induced in the measuring medium can be detected by at least two inserted measuring electrodes electrically insulated from the measuring tube. In order to avoid coupling interference voltages into the electrical electrodes, the first and the second electrode leads can be jointly twisted starting from the leadthrough as far as the first electrode, where the first electrode lead is electrically connected to the first electrode, and the second electrode is connected to a short-circuited conductor loop which encompasses the measuring tube and is connected to the second electrode lead at a location of the first electrode.

Abstract: An arrangement for measuring a current with a Rogowski type current transducer and transducer electronics. The current transducer has a primary conductor winding for carrying the rated current to be measured, and a secondary conductor winding. The secondary conductor winding adapted to induce a voltage signal VS′ between a pair of second terminals. The current transducer having a third conductor winding adapted to receive a calibration current signal. The voltage signal VS′ contains a coil sensitivity S and is a superposition of a rated current voltage signal and an additional calibration signal. The transducer electronics being adapted to amplify both the current voltage signal and the calibration signal in the same amplifier and divide the amplified current voltage signal by that part of the amplified calibration signal that contains the coil sensitivity and the gain.
