Resumo:
This work shows the modeling and control of a system of desalination through reverse osmosis,
fed by a hybrid system of electric power generation, based on sources of renewable energies,
using colored Petri nets as a tool for analysis and projecting.
The proposed approach uses the theory of Petri nets. For elaboration of this work was used
algorithms for enumeration of the states space model and for obtaining the enabling functions
of the net transitions that represents the automation of the desalination system along with the
hybrid energy system.
It was developed a colored Petri net that approached the complete operation of the desalination
system, including the energy hybrid system. Simulations of this net were accomplished
through the computer tool Design/CPN, and the expected results were obtained. Based on
these results, some analysis were performed with the objective of showing that the automation
propose for this process is correct, because all the inherent properties to Petri nets were veri ed.
In other words, the system does not present any problem, such as, dead lock, unreachability,
and non reversibility.
The applied methodology in this work demonstrates the usefulness of Petri nets in the
development of automation in a reverse osmosis desalination process.
