Abstract

Une méthode visant à identifier l'instabilité de tension d'un système d'alimentation en identifiant des lignes et bus les plus vulnérables qui contribuent à la défaillance du système est présentée. La méthode comprend le calcul périodique d'un indice de stabilité de ligne pour les lignes de transport d'électricité surveillées dans le système d'alimentation, et l'utilisation de l'indice de stabilité de ligne élargi pour déterminer la distance d'un état d'opération dans le système d'alimentation à partir d'un point de défaillance du système causé par une instabilité de tension.
