Zusammenfassung:	The invention relates to the field of power engineering, specifically to wind energy installations in which the transmission of energy from a wind turbine to an electric generator happens by means of a hydraulic drive. The wind energy installation with a hydraulic drive comprises a wind turbine, a hydraulic pump installed onto the shaft thereof, and a hydraulic motor connected to the shaft of an electric generator. The hydraulic motor is equipped with a flow limiter. A hydro-accumulating hydraulic cylinder is positioned between the hydraulic pump and the hydraulic motor and contains a hydraulic cavity and a pneumatic cavity separated by a piston. The piston is connected to a stop valve on the delivery pipeline of the hydro-accumulating hydraulic cylinder. The invention makes it possible to increase the operational reliability of a wind energy installation and to improve the quality of the electrical energy produced. L'invention concerne le domaine de la production d'énergie éolienne et notamment des installations de production d'énergie éolienne dans lesquelles la transmission de l'énergie de la turbine éolienne au générateur électrique se fait au moyen d'un entraînement hydraulique. L'installation de production d'énergie éolienne à entraînement hydraulique comprend une turbine éolienne, une pompe hydraulique montée sur son arbre et un moteur hydraulique connecté à l'arbre du générateur électrique. Le moteur hydraulique est doté d'un limiteur de débit. Entre la pompe hydraulique et le moteur hydraulique on a ménagé un vérin hydraulique à accumulateur hydraulique doté de cavités hydraulique et pneumatique séparées par un piston. Le piston est relié à un robinet de verrouillage sur le tuyau d'amenée d'un vérin hydraulique à accumulateur hydraulique. L'invention permet d'augmenter la fiabilité de fonctionnement de l'installation de production d'énergie éolienne et d'améliorer la qualité d'énergie électrique produite.
