Abstract
The aim of this paper is to analysis the water treatment process in a thermal power plant (TPP). In fact, we present an application of a supervisory control and data acquisition (SCADA) system. Thus, an example of a SCADA system of the center of RADES in Tunisia was presented. Our contribution in this work consists in the analysis of the water loss in the TPP on the one hand and the supervision of the water extraction circuit using the SCADA system, on the other hand. Key words: Water extraction, water loss; thermal power plant, supervisory control and data acquisition (SCADA).
Highlights
Every day, we use the electric energy without even to be conscious of it
It is one of the most important centers of the point of view the power installed (700 MWS). It has been inaugurated in 30 of May, 1986. It is about a thermal power plant (TPP) producing electricity while using dry water steam to drag the alternator in rotation, this steam is generated in a furnace that transforms the chemical energy of the fuel in calorific energy
supervisory control and data acquisition (SCADA) systems are used to control and monitor physical processes, examples of which are transmission of electricity, transportation of gas and oil in pipelines, water distribution, traffic lights, and other systems used as the basis of modern society
Summary
We use the electric energy without even to be conscious of it. The electric energy serves in all domains including those where we think that it is not used (central heating of gas, thermal motor-driven vehicles...). Means of production of this energy are very various; we classify them today depending on whether they are based on renewable energies or fossil energies With regards to these last, reserves not being inexhaustible, we tries to replace them by the renewable energies that have for main advantage to be less polluting. Among electricity production centers of the STEG, we mention the center of RADES (near to Tunis, Tunisia) (Annual Report, 2012). It is one of the most important centers of the point of view the power installed (700 MWS). It has been inaugurated in 30 of May, 1986. By reason of the complex requirements and in order to avoid the maximum loss of production, it is extremely important to master all aspects having linked to the security and the profitability of the highest level
