Abstract

Abstract Translated from French Dispositif de régulation de fréquence pour microcentrale de basse chute, utilisant une turbine à roue à pales orientables, d'une puissance supérieure à un Mégawatt, et destinée à alimenter un réseau électrique isolé Le dispositif comporte un absorbeur d'énergie (7) branché aux bornes de la génératrice (2) sous contrôle du régulateur de vitesse (9). L'absorbeur (9) ne peut pas dissiper plus d'une portion (20%) de la puissance nominale et dissipe en permanence la moitié (10%) de cette portion. En dehors d'une fourchette (8%, 12%) autour de cette consigne (10%), le régulateur agit sur le circuit (6) de commande de variation de l'inclinaison des pales. Frequency control device for a low-drop micro power plant, using a turbine with steerable blades, of a power greater than one Megawatt, and intended to supply an isolated electrical network The device comprises an energy absorber (7) connected to the generator terminals (2) under control of the cruise control (9). The absorber (9) cannot dissipate more than one portion (20%) of the nominal power and permanently dissipates half (10%) of this portion. Outside of a range (8%, 12%) around this setpoint (10%), the regulator acts on the circuit (6) for controlling the inclination of the blades.
