Automatic device for optimisation of the discharge of high flood from accumulation lake.

摘要

The invention relates to an automatic device for optimisation of discharge of high flood from accumulation lakes, consisting of a telegauge [1] mounted on the dam, which measures the level [H] of the water in the lake converting it to an analog signal, a constant tension generator [2] which supplies the maximum level of retention for the water in the lake, an algebraic summing device [3] which calculates the difference of the two signals, supplying an exit signal proportional to the level [H] of the water in the lake, which enters in a functional transformer [4] achieved with neuronal network for approximation and learning, which supplies at its exit a signal representing the volume of the water [Vd [H]] which can be discharged into the lake, several telegauges [5] mounted on the tributary rivers, which supply at their exit signals for functional transformers [6] provided with neuronal networks, whose summed exits supply the total tributary river flow rate [Qafl] which constitutes the entry signal into a computational block [7] which calculates the initial moment [TI] from which starts the integration of the total flow rate [Qafl] of the tributary rivers in view of determining the final time [Tf] for the integration, applying a negative reaction, after the calculation of the volume difference [Δ] between the water volume [Vd [H]] which can be discharged to the lake, and the integral of the total flow rate [Qafl] of the tributary rivers , achieved by an integrating block [8], the volume difference [Δ] being obtained by an algebraic summing device [9] whose exit is connected to a computational block [10] which determines the final time [Tf] representing the upper limit of the integral, the exit from the integrating block [B] being the entry to the algebraic summing device.
