SCADA applications in thermal power plants

This paper presents the applications of a supervisory control and data acquisition (SCADA) system in thermal power plants (TPPs). In fact, a supervisory system must take into account the physiological and cognitive features of the supervisory operator. The paper briefly discusses on the one hand the different steps of the application of a SCADA system and the difficulties to manage and on the other hand it presents three examples of the application of a SCADA system in a TPP in Tunisia and the instrumentations and the measurements used. The first application is related to a counting system of the natural gas, the second one is related to the supervision of pumps vibrations and the third one is related to the supervision of heavy fuel oil.
