Title
(EN) CONTROL SYSTEM FOR A VOLTAGE REGULATION DEVICE
(FR) SYSTÈME DE COMMANDE POUR DISPOSITIF DE RÉGULATION DE TENSION
Abstract
(EN) A control system for a voltage regulation device is configured to determine a tap position of a tap changing mechanism of the voltage regulation device, the control system being configured to: determine an internal impedance of the voltage regulation device based on an initial tap position; determine a voltage of the internal impedance based on a measured load current; determine a voltage of the first winding based on the input voltage, the output voltage, and the voltage of the internal impedance; and determine the tap position based on the voltage of the first winding, N, and a voltage of a second winding, where N is an integer value that represents a count of turns on the second winding.
(FR) L'invention porte sur un système de commande pour dispositif de régulation de tension, qui est configuré pour déterminer une position de prise d'un mécanisme de changement de prise du dispositif de régulation de tension, le système de commande étant configuré pour : déterminer une impédance interne du dispositif de régulation de tension sur la base d'une position de prise initiale ; déterminer une tension de l'impédance interne sur la base d'un courant de charge mesuré ; déterminer une tension d'un premier enroulement sur la base d'une tension d'entrée, d'une tension de sortie et de la tension de l'impédance interne ; et déterminer la position de prise sur la base de la tension du premier enroulement, de N et d'une tension d'un second enroulement, N étant une valeur entière qui représente un nombre de spires du second enroulement.
