METHODOLOGY FOR DESIGNING SUPERVISORY SYSTEMS: CASE STUDY OF A COUNTING SYSTEM OF NATURAL GAS

Abstract

After a presentation of the functionality of a supervisory system for complex processes, we present the concepts of SCADA (supervisory control and data acquisition) systems. A methodology for designing supervisory production systems has been presented. This methodology is based on a functional analysis technique SADT (Structured Analysis and Design Technique) and has been applied on an example of a SCADA system of a thermal power plant (TPP). This technique allows a functional description of a SCADA system. An application of supervision of a counting system of the natural gas of a TPP is presented.
