Graphic analysis and planning of electrical distribution systems

Abstract

Techniques for computer modeling of electrical distribution systems have been available to utility engineers for years. The formation of a distribution data base can be a huge task because of the enormous number of components in a utility's distribution system. The continuous changes that occur in a distribution system make data base maintenance difficult. Application of computer graphics to distribution engineering simplifies data base formation and maintenance and aids in interpreting the results of analysis. Graphic-aided distribution analysis allows the engineer to quickly see the results of alternate modes of system operations, thus speeding the iterative process of decision-making. Future applications for graphics techniques in utilities extend to distribution SCADA, work order prepration and protective device coordination.
