SCADA application of a water steam cycle of a thermal power plant

Abstract

The aim of this paper is to present the process of water treatment in a thermal power plant (TPP) in the one hand, and an application of a supervisory control and data acquisition system (SCADA) on the other hand. In fact, almost all critical industrial infrastructures and processes are managed remotely from central control rooms, using computers and communications networks. Thus, the architecture of the supervisory system and the different steps of the supervision application of the water treatment process of a TPP have been presented. Our contribution consists in programming and visualizing new parameters of the chemical analysis (pH and conductivity) of the water -steam cycle to a SCADA system. The achieved supervision application is going to facilitate the work of both laboratory and instrumentation agents of the water treatment process in the TPP.

Application of System Analysis in Order to Monitor Grain Silos

“…The grain storage technique is of great importance in Tunisia. In this part, we present a proposal of an automated system for the controlling and monitoring of the grain storage using Programmable Logic Controller (PLC) and Supervisory Control and Data Acquisition (SCADA) [19,20]. In fact, the main parameter that is essential for proper storage of grains is temperature which is taken as input parameter to be controlled using PLC and is measured using a temperature sensor.…”
