Abstract
Economic pressures, the rapid evolution of technology and rapid population growth make it imperative to maximize asset reliability at the optimum cost. Life-cycle cost analysis begins with the design and selection of new or replacement assets. Procurement takes place only after the initial stages (asset strategy, plan, evaluate and design) are completed. This is followed by the cost of operating, maintaining and sometimes modifying the asset before its eventual disposal. This paper presents brief history and a state of the art study of Life Cycle Cost Analysis (LCCA), in particular LCC analysis in Power Distribution Systems, based on a detailed literature assessment and interviews with experts. Life cycle costs Analysis (LCCA) are support to serious costs summarized as an economic model of evaluating alternatives for equipment’s and projects. A main objective of the LCC analysis is to quantify the total cost of ownership of a system throughout its full life cycle, which includes research and development, construction, operation and maintenance, and disposal. LCC calculates the total cost for Power Distribution System during its lifetime. The total cost includes planning, operation, equipment’s purchase, and maintenance and power cut. The predicted LCC is useful information for decision in optimizing design, in scheduling maintenance, or in planning revamping. In this article we present a LCC procedure consisting of six steps, which are “Problems definition in introduction”, “System modelling”, “Cost elements definition”, “Data collection”, “Cost profile development”, and “Evaluation”.
