Title
(EN) SYSTEMS AND METHODS FOR GROUND FAULT DETECTION IN POWER SYSTEMS USING COMMUNICATION NETWORK
(FR) SYSTÈMES ET PROCÉDÉS UTILISANT UN RÉSEAU DE COMMUNICATION POUR DÉTECTER UN DÉFAUT À LA TERRE DANS DES SYSTÈMES D'ALIMENTATION ÉLECTRIQUE
Abstract
(EN)
Systems, methods, storage media, and computing platforms for determining a fault in a power system, executing on a controller are disclosed. Exemplary implementations may: receive a first value of current flow from a first current sensor installed on a first bus of the power system; receive a second value of current flow from a second current sensor installed on a second bus of the power system; determine a first direction of power flow in the first current sensor using the first value of current flow; determine a second direction of power flow in the second current sensor using the second value of current flow; and determine a power fault is located on one of the first bus of the power system or the second bus of the power system based on the first direction of power flow and the second direction of power flow.

L'invention concerne des systèmes, des procédés, des supports d'informations et des plates-formes informatiques permettant de déterminer un défaut dans un système d'alimentation électrique, exécutés sur un dispositif de commande. Des exemples de mises en oeuvre consistent à : recevoir une première valeur de flux de courant provenant d'un premier capteur de courant installé sur un premier bus du système d'alimentation électrique ; recevoir une seconde valeur de flux de courant provenant d'un second capteur de courant installé sur un second bus du système d'alimentation électrique ; déterminer une première direction du flux de courant dans le premier capteur de courant à l'aide de la première valeur de flux de courant ; déterminer une seconde direction de flux de courant dans le second capteur de courant à l'aide de la seconde valeur de flux de courant ; et déterminer la présence d'un défaut électrique sur le premier bus ou le second bus du système d'alimentation électrique sur la base de la première direction et de la seconde direction du flux de courant.
