Title
(EN) METHOD AND TURBINE CONTROL SYSTEM FOR CONTROLLING ROTATIONAL SPEED OF A TURBINE
(FR) PROCÉDÉ ET SYSTÈME DE COMMANDE DE TURBINE PERMETTANT DE RÉGULER LA VITESSE DE ROTATION D'UNE TURBINE
Abstract
(EN) A method and a controller (101) is disclosed for controlling rotational speed of a turbine (122) in a turbine system (105). The turbine system (105) comprising the turbine (122), a pressure sensor (130), a filter (132) and a drive unit (126). The controller performs the method and collects (S100) sensor data from the pressure sensor (130) and the drive unit (126), compares (S102) the collected sensor data with reference values to determine if the collected sensor data is valid, calculates (S104) the current operating point of the turbine system (105) based on the collected sensor data and system parameters of the turbine system (105), determines (S106) a current optimal rotational speed of the turbine based on the current operating point, checks (S108) the validity of the current optimal rotational speed by using the filter and controls (S112) the drive unit (126) to drive the turbine at the determined current optimal rotational speed.
(FR) La divulgation concerne un procédé et un dispositif de commande (101) permettant de réguler la vitesse de rotation d'une turbine (122) dans un système (105) de turbine. Le système (105) de turbine comprend la turbine (122), un capteur de pression (130), un filtre (132) et une unité d'entraînement (126). Le dispositif de commande effectue le procédé et collecte (S100) des données de capteur en provenance du capteur de pression (130) et de l'unité d'entraînement (126), compare (S102) les données de capteur collectées à des valeurs de référence afin de déterminer si les données de capteur collectées sont valides, calcule (S104) le point de fonctionnement actuel du système (105) de turbine en fonction des données de capteur collectées et des paramètres du système (105) de turbine, détermine (S106) une vitesse de rotation optimale actuelle de la turbine en fonction du point de fonctionnement actuel, vérifie (S108) la validité de la vitesse de rotation optimale actuelle à l'aide du filtre, et amène (S112) l'unité d'entraînement (126) à entraîner la turbine à la vitesse de rotation optimale actuelle déterminée.
