Abstract

Procédé et appareil de détection en boucle fermée entièrement automatique pour une sous-station intelligente. Le procédé comporte les étapes consistant à: comparer un fichier SCD d'une sous-station testée avec un fichier modèle de données de type de dispositif, de façon à déterminer si des informations de configuration de la sous-station testée sont correctes (101); lorsqu'il est déterminé que les informations de configuration de la sous-station testée sont correctes, analyser le fichier SCD de la sous-station testée, et générer un diagramme topologique de SSD de la sous-station testée (102); et obtenir un élément de test issu d'une bibliothèque préétablie d'éléments de test d'après le diagramme topologique de SSD de la sous-station testée, et générer une solution de test de la sous-station testée et effectuer un test d'élément, et délivrer le résultat de test (103). La solution résout le problème du faible niveau de visualisation dû à l'absence de création automatique d'une solution de test dans un test existant de détection en boucle fermée pour une sous-station intelligente.
