Abstract

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.

Key words: SCADA, supervision, control, data acquisition, thermal power plant.
