Automation and supervision for desalination station of SONELGAZ Combined Cycle power plant(Ras-Djinet)

Abstract

This project aims to replace the current automated system at the Ras Djinet power plant's desalination station, which employs an ABB PAC8000 (8521-HC-MT) controller. The existing controller has several drawbacks, including high cost, complexity, and challenges with upgrades, these drawbacks necessitate the exploration of alternative solutions to optimize the performance and maintainability of the desalination plant's control infrastructure. To address these issues, we propose replacing the ABB controller with a Siemens S7-300 controller that offers enhanced reliability and user-friendliness, making it a more suitable solution for the desalination station's control system. The handling of alarms and the switching between manual and automatic modes have also been taken into account. In addition, we have used the WinCC program integrated into TIA PORTAL to build a supervision system for the desalination station.
