    摘要: Certain aspects and features include a system and method for energy measurement in electric meter systems. In an example, an electric meter receives an Alternating Current (A/C) signal. The electric meter includes a current measurement device that is configured to obtain a current measurement of a current of the A/C signal. The current measurement includes a fundamental frequency component and a noise component. The electric meter receives a current measurement signal from the current measurement device and filters the noise component from the current measurement, thereby creating a filtered current measurement signal. When the filtered current measurement signal is greater than a starting current threshold, the electric meter calculates an energy consumption measurement.

    摘要: A system for crosstalk cancelation for electricity metering in a power distribution network is provided. For example, a meter can be used to generate a set of measurement points by measuring electrical signals provided by a reference power device according to a set of source points. Based on the set of source points and the corresponding set of measurement points, a crosstalk cancelation function is derived and stored in the meter. When the meter is deployed at a geographical location and generates a measurement point by measuring the electrical signal on the power distribution network, the meter further applies the crosstalk cancelation function to the measurement point to generate a transformed measurement point. The meter calculates various characteristics of the power distribution network based on the transformed measurement points and transmits the calculated characteristics to a headend system.

    摘要: Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur kontaktlosen, nicht-invasiven Messung von elektrischen Leistungsgrößen (I) in einer elektrischen Leitung (1) mit mindestens zwei Adern (2), wobei ausschließlich zumindest ein Teil der gemessenen Leistungsgrößen selbst zur Kalibrierung der Messung genutzt wird, wobei eine Messvorrichtung (4) mit die elektrische Leitung (1) umgebenden Magnetfeldsensoren (6) im Wesentlichen in einer die elektrische Leitung (1) schneidenden Messebene (8) angeordnet wird und wobei in einem Kalibrierungsvorgangaus Messwerten der Magnetfeldsensoren (6) die Positionen der Adern (2) in der Messebene (7) und die elektrischen Leistungsgrößen (I) anhand eines Modells in einem konvergierenden iterativen Verfahren gleichzeitig bestimmt werden. Vorzugsweise wird die Kalibrierung während laufender Mes- sungen periodisch oder episodisch wiederholt, um genaue Messungen auch bei sich ändernden thermischen oder mechanischen Bedingungen zu gewährleisten. Die Erfindung ist besonders für die Messung von Leistungsgrößen in Stromversorgungsnetzen geeignet und kann an Kabeln verschiedener Durchmesser mit unterschiedlichen Anzahlen von Adern eingesetzt werden. Durch eine sich im Betrieb wiederholende Kalibrierung ist das Messsystemsehr robust und kann auch unter nicht statischen Bedingungen und unter mechanischen und thermischen Belastungen mit hoher Messgenauigkeit eingesetzt werden.

    摘要: Systems and methods for managing resource consumption. In some embodiments, a consumption management system is provided, comprising at least one storage medium storing a hierarchical data structure, and at least one processor programmed to access the hierarchical data structure. The hierarchical data structure may comprise a first level, a second level, and a third level, the third level being lower than the first level and the second level. The first level may comprise a plurality of nodes corresponding, respectively, to a plurality of locations, the plurality of nodes at the first level comprising a first node. The second level may comprise a plurality of nodes corresponding, respectively, to a plurality of load categories, the plurality of nodes at the second level comprising a second node that descends from the first node. The third level may comprise a plurality of nodes corresponding, respectively, to a plurality of resource consumption meters, the plurality of nodes at the third level comprising a third node that descends from the second node. A resource consumption meter corresponding to the third node may be located at a location corresponding to the first node, and may measure resource consumption of one or more pieces of equipment that fall under a load category corresponding to the second node.

    摘要: The method for determining mutual voltage sensitivity coefficients between a plurality of measuring nodes (M1,..., M7) of an electric power network (1) does not rely on knowledge of the network parameters (for example: series conductance and susceptance of the branches, shunt conductance and susceptance of the nodes, etc.). The method uses a monitoring infrastructure comprising metering units at each one of the measuring nodes, and it comprises a step of measuring at the same time, at each one of said measuring nodes (M1,..., M7), repeatedly over a time window ( τ ), sets of data comprising values of the current ( Ĩ (t)), the voltage ( V (t)), and the phase difference ( φ ( t )), a step of computing active power ( P ( t )) reactive power ( Q ( t )) values from each set of measured data, and a step of performing multiple parametric regression analysis of the variations of the voltage at each one of the measuring nodes.
