SCADA application of a Water Steam Cycle of a Thermal Power Plant

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.
