IEC 61970-302:2018

Energy management system application program interface (EMS-API) - Part 302: Common information model (CIM) dynamics

IEC 61970-302:2018 specifies a Dynamics package which contains extensions to the CIM to support the exchange of models between software applications that perform analysis of the steady-state stability (small-signal stability) or transient stability of a power system as defined by IEEE/CIGRE Definition and classification of power system stability IEEE/CIGRE joint task force on stability terms and definitions. The model descriptions in this standard provide specifications for each type of dynamic model as well as the information that needs to be included in dynamic case exchanges between planning/study applications.

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Partie 302: Régimes dynamiques de modèle d'information commun

L'IEC 61970-302:2018 spécifie un paquetage dynamique (Dynamics) contenant des extensions du CIM. Il s'agit d'assurer l'échange des modèles entre les applications logicielles qui procèdent à l'analyse de la stabilité en régime établi (stabilité en petits signaux) ou de la stabilité transitoire d'un système de puissance tel que défini dans le document Definition and classification of power system stability (Définition et classification de la stabilité des réseaux d’énergie électrique) du joint task force (groupe de travail commun) IEEE/CIGRE on stability terms and definitions. Les descriptions de modèles indiquées dans la présente norme donnent des spécifications pour chaque type de modèle dynamique, ainsi que des informations nécessaires à inclure dans les échanges de cas dynamiques entre les applications de planification/d'étude.
