Abstract
This report presents a hybrid model that calculates the heads and flow rates 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 the Matrix Method was used. 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 satisfactorily, 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 satisfactorily, because the objective function
values calculated by the model converged whenever the elitism was used. The
proposed optimization in this work is to be used in hydraulic networks that
present operational problems that need to be solved either by installing valves or
having installed valves.
Keywords: hydraulic networks operation, optimization.
1 Introduction
Optimization is a search process for a problem solution that uses several
techniques to find the most efficient solution.
The operational control optimization of hydraulic networks is usually
obtained using linear programming with several restrictions, because the
equations that represent the flow rate are non-linear.
Keywords
hydraulic networks operation, optimization.
