Distributed control of the sewage system

This work is complementary to the implementation of a large automation project for a public sewer system. The main focus was the simulations-based analysis of the hydraulics of the system and the real time linking with the controller. The purpose was to test different sets of routines and parameters prior to the start up of the real system running in the 800xA DCS (Distributed Control System) platform from ABB. The simulation was programmed in the Matlab-Simulink environment, in order to analyze the behavior of the plant against different input flows and variations on it's internal parameters. The simulation framework communicates directly with the physical controller through the Open Platform Communication protocol (OPC).
