HYDRAULIC TURBINE CONTROL DEVICE

摘要

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, characterized in that it comprises first control means (100) and second power means (200); wherein said first means (100) are 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 said first control means (100) act on the second power means (200) for causing the application of the braking torque necessary to maintain a stable set-point value on the turbine (3).
