  • Method for operating a hydraulic machine and corresponding installation for converting hydraulic energy into electrical energy
    Patent number: 11248578
    Abstract: This installation for converting a hydraulic energy into electrical energy comprises a hydraulic adapted to be operated either in a pump mode or in a turbine mode. It further comprises means (25) for applying an electric torque to the rotor to control the rotation speed of the machine during transitions between the pump mode and the turbine mode.
    Type: Grant

  • Stabilization of hydraulic machines with S-zone characteristics
    Patent number: 11239778
    Abstract: This method for stabilizing the rotation speed of a hydraulic machine having S-characteristic and comprising a distributor (9) is adapted to modify a water flow, so that the machine can be coupled to a grid. The method comprises the steps of calculating an orientation of the distributor (9); and orienting the distributor according to the calculated orientation. The method further comprises the steps of providing an electric torque to the machine so as to reach a target speed.
