Abstract

L'invention concerne un procédé de simulation de communication sur la base de la norme CEI 61850 destiné à un dispositif de surveillance en ligne d'isolation. Le procédé comprend les étapes suivantes consistant à : (1) lancer un service de communication selon la norme CEI 61850/MMS par simulation; (2) interroger des valeurs de quantités analogiques, prémémorisées dans une base de données SQL, d'une analyse portant sur un dispositif électronique intelligent de surveillance en ligne d'isolation devant faire l'objet d'une simulation; (3) établir des règles d'alarme en utilisant les limites de télémesure préconfigurées et calculer automatiquement des états de télésignalisation d'alarme correspondants; (4) envoyer les quantités analogiques et les états de télésignalisation d'alarme sous la forme d'un rapport selon la norme CEI 61850; et (5) attendre le prochain moment d'envoi de données, puis recommencer à l'étape (2) jusqu'à ce que toutes les données prémémorisées soient envoyées. Un PC ordinaire peut être utilisé pour simuler un appareil de surveillance en ligne d'isolation de façon à déboguer et vérifier d'une manière pratique et flexible des applications évoluées, telles qu'une évaluation de l'état de divers arrière-plans et dispositifs principaux d'une sous-station intelligente, ce qui nécessite de communiquer avec le dispositif électronique intelligent de surveillance en ligne.
