SYSTEMIC ANALYSIS OF A SUPERVISORY CONTROL AND DATA ACQUISITION SYSTEM

Abstract

This paper tries to present firstly the functionality of a supervisory system for complex processes, and secondly the concepts of a supervisory control and data acquisition (SCADA) system. Our contribution consists on applying a systemic analysis method OOPP (Objective Oriented Project Planning) on a SCADA system of a thermal power plant (TPP).The paper briefly discusses the functions of a SCADA system and some advantages of the application of the OOPP method for the analysis of a human centered supervisory system. Then the basic principles of the OOPP method applied on the SCADA system are presented. Finally, an application of supervision of the signals of the chemical analysis in a TPP is presented.
