An asset management technique applicable in electrical systems

Abstract

This paper focuses on presenting an asset management technique that may be used to assist prioritization of assets within electrical networks for major refurbishment/re-engineering exercises. A multi-criteria approach is adopted to this aim, making use of quantifiable measures of features that can be attached to complex groups of installation within electrical networks. Technical condition in conjunction with conveyed electric energy, to which operational and strategic importance measures are added, will be at the core of a grading mechanism that finally produces an objective hierarchy within a given set of entities from the electrical network. The technique is described in the paper and critical aspects related to its implementation are also discussed. As with all multi-criteria approaches the selection of weighting coefficients set is one of the key elements for the success of the technique when it comes to achieve a good discrimination feature against a variety of conditions. Results from the implementation of technical condition assessment component to an individual real-life problem are presented also.
