COMPUTER-AIDED DISTRIBUTION-SYSTEM PLANNING

The purpose of this paper is to demonstrate how computerized design models, supported by computer graphics, can aid in electric distribution planning. The models comprise siting and sizing of primary substations, primary feeder routing, and secondary network design.1,2 The modelling is performed with an emphasis on rapid, descriptive design methods with geographical reference in planning data and resulting distribution system layouts. This enables a planner to provide and present many low cost designs, compatible with projected loads and community plans, in a graphical form that is both accurate and easy to understand. The designs may then be completed with further technical and economic analyses and embodied in a utility decision basis for future long- and short-term system perspectives. © 1979.
