The application of multi-criteria analysis to substation design

This paper presents an approach to substation design based on a multicriteria analysis. It describes the four criteria and how they are applied, first of all to the selection of credible designs and then to the evaluation of these designs to arrive at the most promising result. The substation structure is described in terms of its five composite groups and defined by the single-line diagram and the associated equipment. The process of selecting suitable configurations (single-line diagram) and associated electrical equipment is based on the multi-criteria approach. This approach is further refined to incorporate user preferences with respect to the chosen four criteria so as that the final design is representative of both the design specifications and the concerns of the user.
