Sažetak
A concept of a water supply plant control system is proposed that ensures output pressure stabilisation under conditions of variable water consumption and variable water resourses. The control system consists of inner control loops which control the flow of each pump station and of superimposed control loop that controls output pressure of the water supply plant. The pressure controller calculates the cumulative reference value of the water flow for all controlled pumps and from this value an algorithm for the flow distribution calculates the reference flow for each inner loop, taking into account the level of water accumulation in each water well. Control system performances were investigated by simulations on the water supply plant Mala Mlaka near Zagreb. It has been shown that the system exhibits more robust behaviour if a fuzzy logic controller of output pressure is used instead of a conventional PI controller.
