Title

(FR) DÉTECTION D'ÉCART EN TEMPS RÉEL DE CARACTÉRISTIQUES ÉLECTRIQUES D'UN SYSTÈME D'ALIMENTATION À L'AIDE DE MESURES SYNCHRONISÉES DANS LE TEMPS
Abstract
(EN)
Systems, methods, and products are described herein for identifying deviations within a power system. Using time-synchronized measurement devices, a set of voltages and currents associated with a plurality of electrical components within the power system are continuously measured. For each electrical component of the plurality of electrical components, a representative set of parameters are recursively determined based on the measured set of voltages and currents. For each electrical component, an electrical characteristic value is determined based on the representative set of parameters. For each electrical component, a deviation of the electrical component is identified based on comparison of the determined electrical characteristic value with a reference value of the electrical characteristic of the electrical component or based on identifying the deviation by means of a filtered rate of change. An alert of the deviation is provided for further characterization of an abnormality in the power system.

L'invention concerne des systèmes, des procédés et des produits permettant d'identifier des écarts dans un système d'alimentation. À l'aide de dispositifs de mesure synchronisés dans le temps, un ensemble de tensions et de courants associés à une pluralité de composantes électriques à l'intérieur du système d'alimentation sont mesurés en continu. Pour chaque composante électrique de la pluralité de composantes électriques, un ensemble représentatif de paramètres est déterminé de manière récursive en fonction de l'ensemble mesuré de tensions et de courants. Pour chaque composante électrique, une valeur caractéristique électrique est déterminée en fonction de l'ensemble représentatif de paramètres. Pour chaque composante électrique, un écart de la composante électrique est identifié en fonction d'une comparaison de la valeur caractéristique électrique déterminée avec une valeur de référence de la caractéristique électrique de la composante électrique ou en fonction de l'identification de l'écart au moyen d'un taux de variation filtré. Une alerte de l'écart est fournie pour une caractérisation supplémentaire d'une anomalie dans le système d'alimentation.
