Title (EN) APPARATUS FOR CONTROLLING A HYDRAULIC MACHINE
(FR) DISPOSITIF DE RÉGULATION D’UNE MACHINE HYDRAULIQUE
(DE) VORRICHTUNG ZUM REGELN EINER HYDRAULISCHEN MASCHINE
Abstract:
(EN) Apparatus for controlling a hydraulic machine, e.g. a turbine, a pump or a pump-turbine, using constant-displacement pumps that are driven at variable rotational speeds, said apparatus comprising a device for performing an emergency closure, the device being characterized by low energy consumption and high efficiency while ensuring that all operation-relevant and safety-relevant requirements of a hydraulic machine are met.
(FR) L'invention concerne un dispositif de régulation d’une machine hydraulique, par exemple d’une turbine, d’une pompe ou d’une turbine de pompe, au moyen de pompes à cylindrée constante entraînées avec une vitesse de rotation variable, comprenant un dispositif d'exécution d'une coupure d'urgence, ledit dispositif de régulation se caractérisant par une faible consommation d'énergie et une grande efficacité tout en garantissant toutes les exigences de fonctionnement et de sécurité d'une machine hydraulique.
(DE) Vorrichtung zum Regeln einer hydraulischen Maschine, z.B. einer Turbine, einer Pumpe oder einer Pumpturbine, unter Verwendung von drehzahlvariabel angetriebenen Konstantpumpen umfassend einer Einrichtung zum Ausführen eines Notschlusses, welche sich durch geringen Energieverbrauch und hohe Effizienz unter Gewährleistung aller betriebs- und sicherheitsrelevanten Anforderungen einer hydraulischen Maschine auszeichnet.
