Contributions to the Analysis and the Supervision of a Thermal Power Plant

Abstract

Abstract-Supervision systems play an important role in industry mainly due to the increasing demand for product quality and high efficiency, and to the growing integration of automatic control systems in technical processes. In fact, the supervision system has a great number of components and interconnections, and it is difficult to describe and understand its behavior. Furthermore, the supervision system in industrial plants, implemented in supervisory control and data acquisition (SCADA) software, must undertake, at least, the following three main tasks: monitoring, control and fault tolerance. So it can be classified as a complex system. The objective of this paper is to show interests of the use of functional analysis techniques such as SADT (Structured Analysis and Design Technique) and SA-RT (Structured Analysis Real Time) for the design of supervisory systems. This is why we present a general model of analysis and supervision of production systems. This model was based on the one hand on the functional analysis (FA) and on the other hand on the SCADA system.

SCADA and Distributed Control System of a Chemical Products Dispatch Process

“…With the purpose of supervising, monitoring and acquiring data for decision-making on aspects related to the operation or operation of an industrial process, SCADA systems (Supervisory Control and Data Acquisition) are used [14][15][16][17]. The application of SCADA systems is diverse, however among the processes that use it the most are electricity generation, natural gas, mining deposits, thermal systems, oil pipelines and chemical products dispatch [18][19][20]. One aspect to highlight in SCADA systems is that they allow in a friendly way to show the behavior of the critical variables in a process, becoming a strategic element at the industrial level, integrally linking geographically dispersed subsystems arranged in a plant [21][22][23].…”
