2.1 SCADA SYSTEMS
ОглавлениеSCADA (Supervisory Control And Data Acquisition) is an important computer‐controlled industrial system that continuously monitors and controls many different sections of industrial infrastructures such as oil refineries, water treatment and distribution systems, and electric power generation plants, to name a few. A SCADA system is responsible for supervising and monitoring industrial and infrastructure processes by gathering measurements and control data from the deployed field devices at the field level. The collected data are then sent to a central site for further processing and analysis. The information and status of the supervised and monitored processes can be displayed on a humanmachine interface (HMI) at the home station in a logical and organized fashion. If an abnormal event occurs, the operators can analyse the gathered data and put in place the necessary controls. Because these industrial systems are large and distributed complexes, it is necessary to continuously and remotely monitor and control different sections of the plant in order to ensure its proper operation by a central master unit.
