Abstract: Control device for hydraulic turbines configured to adjust the resistant torque provided by the generator to the movement of the impeller of an hydraulic turbine so that a stable pressure is set at the inlet (Pi) and at the outlet (Po) regardless of the circulating flow rate (Q), and to adjust the electrical energy produced by the turbine to achieve the desired hydraulic behavior, the device comprising a controller and a power device; wherein said controller is connected to a pressure detector at the inlet (Pi) and at the outlet (Po) and to a flow-meter for obtaining the circulating flow rate (Q), as well as to a power sensor for measuring the power of the turbine; all this, in such a way that the controller acts on the power device for causing the application of the braking torque necessary to maintain a stable set-point value on the turbine.

Abstract: Control device for hydraulic turbines configured to adjust the resistant torque provided by the generator to the movement of the impeller of an hydraulic turbine (3) so that a stable pressure is set at the inlet (Pi) and at the outlet (Po) regardless of the circulating flow rate (Q), and to adjust the electrical energy produced by the turbine to achieve the desired hydraulic behavior, the device comprising a control means (100) and a power means (200); wherein said control means (100) is connected to means for detecting the pressure at the inlet (Pi) and at the outlet (Po) and to a flow-meter (1) for obtaining the circulating flow rate (Q), as well as to means for measuring the power (2) of the turbine (3); all this, in such a way that the control means (100) acts on the power means (200) for causing the application of the braking torque necessary to maintain a stable set-point value on the turbine (3).
