Title
(EN) ELECTRICITY PRODUCTION SYSTEM COMPRISING A HYDRAULIC TURBINE, WITH AN IMPROVED DYNAMIC RESPONSE
(FR) SYSTÈME DE PRODUCTION D'ÉLECTRICITÉ COMPRENANT UNE TURBINE HYDRAULIQUE, AVEC UNE RÉPONSE DYNAMIQUE AMÉLIORÉE
Abstract
(EN) The invention relates to an energy production system (1) comprising: - a hydraulic turbine system (3) having undesirable electrical power output setpoints and identified safe electrical power output setpoints; - an energy storage system (14); - a connection (6) connected to the energy storage system (14) and to an electric machine of the hydraulic turbine system (3), and connected to an AC power network (2); - a device for determining the state of charge (19); - a control circuit (18) controlling a transfer of electrical power between the connection (6) and the energy storage system (14), configured to receive an electrical power setpoint value Reps and configured to determine that this received electrical power setpoint value Reps belongs to the undesirable electrical power output setpoint values, to generate an electrical power transfer setpoint value Epts, and an actual electrical power output setpoint value Aepos belonging to the safe electrical power output setpoint values, satisfying the relationship Reps = Epts + Aepos.
(FR) L'invention concerne un système de production d'énergie (1), comprenant : - un système de turbine hydraulique (3) ayant des points de consigne de sortie de puissance électrique indésirable et des points de consigne de sortie de puissance électrique sûre identifiés; - un système de stockage d'énergie (14); - une liaison de connexion (6) reliée au système de stockage d'énergie (14) et à une machine électrique du système de turbine hydraulique (3), et connectée à un réseau courant alternatif (2); - un dispositif de détermination de l'état de charge (19); - un circuit de commande (18) contrôlant un transfert de puissance électrique entre la liaison de connexion (6) et le système de stockage d'énergie (14), configuré pour recevoir une valeur de consigne de puissance électrique Reps et configuré pour déterminer que cette valeur de consigne de puissance électrique reçue Reps appartient aux valeurs de consigne de sortie de puissance électrique indésirable, pour générer une valeur de consigne de transfert de puissance électrique Epts, et une valeur de consigne de sortie de puissance électrique réelle Aepos appartenant aux valeurs de consigne de sortie de puissance électrique sûre, satisfaisant la relation Reps = Epts + Aepos.
