An Internet Based Distributed Control Systems: A Case Study of Oil Refineries

Energy and Power Engineering 2011年第3期3卷 310-316页

作者： musaria k. mahmood Fawzi M. Al-Naima Department of Electrical Engineering College of Engineering Tikrit University Department of Computer Engineering College of Engineering Nahrain University

An Internet based Distributed Control System (DCS) is presented in this paper for monitoring real time data using ordinary web browser. Each DCS will be connected to the central server which will be the system web server. The proposed system is based on the three-tier client-server model. The application server is written in C#.Net. SQL database server 2005 is used for all the DCSs local database servers and for the system database server. Monitoring real time system alarm and all historical records are considered as part of the proposed system. The North Oil Refineries of Baiji (NORB) in northern Iraq is considered as a case study for the developed system. These refineries have twelve independent DCSs which are connected in a mesh network.to form one system similar to an ordinary Supervisory Control And Data Acquisition (SCADA) system.

Developing a Multi-Layer Strategy for Securing Control Systems of Oil Refineries

Wireless Sensor Network 2010年第7期2卷 520-527页

作者： musaria k. mahmood Fawzi M. Al-Naima 不详

The energy industry and in particular the Oil Refineries are extremely important elements in Iraq’s infrastructure. A terrorist attack.on one oil refinery will have a catastrophic impact on oil production and the whole economy. It can also cause serious damage to the environment and even losses of human lives. The security of information systems and industrial control systems such as Supervisory Control and Data Acquisition (SCADA) systems and Distributed Control System (DCS) used in the oil industry is a major part of infrastructure protection strategy. This paper describes an attempt to use several security procedures to design a secure, robust system for the SCADA and DCS systems currently in use in the North Oil Refinery in the city of Baiji located in northern Iraq.
