    • The DINN hydroturbine is based on new energy transfer from the fluid to the mechanical system, aided by devices that reduce the viscous friction that occurs during rotation between the working fluid and the inner wall of the stator (1). The conversion of fluid energy into mechanical work during rotation relies on the utilization of centrifugal and centripetal force. During operation, the fluid flowing around the stator circle (1) changes direction and speed. So that by changing the direction and speed of fluid flow, the centrifugal force weakens and the centripetal force increases. In this way, the spiral movement of the fluid towards the center, ie the turbine outlet shaft (11), is established. The fluid rotates in spirals to a given speed, transferring energy to the mechanical system, after which it exits the turbine. The DINN hydroturbine is designed for turbine and pump operation. The field of technology is mechanical engineering, the field of application is hydropower.

    • System and method for controlling operation of a hydroelectric production system comprising electrical actuators operably connected at opposite positions of a gate operating ring for rotating the wicket gates to a desired position. The system receives a single control signal designed for a hydraulic system comprising hydraulic actuators operably connected to a single fluid reservoir and configured to work in tandem to produce simultaneous and opposite axial movements. The system comprises a control interface adapted to produce new control signals, each new signal being intended to a different electrical actuator to cause the electrical actuators to have axial movements which are identical in speed and in opposite directions to substantially imitate the exact movement of the hydraulic actuators onto the gate operating ring. The system is configured to introduce a dampening effect to reduce sudden acceleration and deceleration which is purposely used in hydraulic systems to overcome friction and static effects.

    • Distributeur mobile à deux degrés de liberté destiné à équiper des turbomachines de type Francis ou turbine-pompe radiale, permettant de faire varier par une action combinée deux rotations, d'une part l'angle d'ouverture des directrices, et d'autre part l'angle d'ouverture de paliers excentrés affectant le valeur du rayon d'implantation des directrices, dans le but de pouvoir modifier l'angle des filets fluides au bord de fuite des directrices et le débit de fluide à l'entrée de la roue de la turbomachine. Une loi de conjugaison tridimensionnelle permet de piloter l'asservissement du rayon d'implantation des directrices en fonction de la consigne d'ouverture des directrices et de la valeur de la chute, en vue d'élargir la caractéristique de rendement en fonction du débit, de stabiliser le fonctionnement à charge partielle, et de retarder l'apparition de cavitation sur les aubages de la roue de la turbomachine.
