| Abstract | |
This report presents a hybrid model that calculates the heads and flows of a hydraulic network system and then uses a genetic algorithm to optimize the operational control of the hydraulic network. To calculate the steady flow and the extensive period it was used the Matrix Method. The GA used binary numbers. The objective function minimizes the sum of the dissipated hydraulic power in the whole network of all calculated periods during the day. The hybrid model part that refers to the hydraulic calculation is working well, because the values calculated by the model applied to the networks used as examples are similar to the ones obtained from the technical literature. The hybrid model part that refers to the GA is working well, because the objective function values calculated by the model converged whenever the elitism was used. The proposed optimization of this work is to be used in hydraulic networks that present operational problems that need to be solved either installing valves or having installed valves. (AU) | |
