RODRIGUEZ MARTINEZ, Alberto; BENITEZ PINA, Israel  and  MULET HING, Mónica. Synchronization and Integration in SCADA of a desalination process. RTQ [online]. 2019, vol.39, n.2, pp. 334-354. ISSN 2224-6185.

In this work, a SCADA system is designed and implemented with the MOVICON 11.5 software, in which the operation of five seawater desalination lines by reverse osmosis which work in parallel, with four coastal wells and two end-of line pumps of the permeated water obtained are integrated, synchronized and supervised as a single plant. Each desalination line has its own control system and can operate independently. From the state of the art synchronization algorithms were obtained that are added to the SCADA system through script codes. The study of the necessary characteristics in the processes managed avoid simultaneous operations that affected the performance of the osmosis lines. Productive continuity in the desalination process was guaranteed by means of algorithms added to the SCADA, which achieve synchronization between the mentioned sub-processes, in the MOVICON 11.5 system. Alarms are generated, reports, historical records and trends are created as a basis in the decision making on prediction of failures, predictive maintenance and troubleshooting, allowing to increase the efficiency in the integrated management of the process. It also configures the interface of the Android App available in the aforementioned SCADA for remote management.

Keywords : optimal operation of water resources systems; integrated plant control; sequential control algorithms; supervisory control; industrial communication protocols.
