Abstract

A device for controlling the injection of at least one operating fluid in an evolving fluid of a plant (1) for the production of electrical energy is provided with: a calculation unit (38) for calculating at least one flowrate (Q1, Q2) of operating fluid to be injected into the evolving fluid on the basis of a detected parameter (C1, pH) of the evolving fluid modified by the operating fluid, which is configured for calculating the flowrate (Q1, Q2) of operating fluid to be injected according to a first mode when the detected parameter (C1, pH) is lower than a given threshold value (CTS, pHTS) and according to a second mode when the detected parameter (C1, pH) is higher than the threshold value (CTS, pHTS); and a driving unit (39) for driving at least one operating fluid injection pump (32, 36) on the basis of the flowrate (Q1, Q2) of operating fluid calculated.
