Risk Assessment of Power Transformer Life Cycle Cost Based on Extensible Matter-Element Model

Article Preview

Abstract:

Making assessment of risk factors of power transformer life cycle cost modeling is an important mean of improving the scientificity of transformer life cycle cost management. Considering the risk factors of transformer life cycle cost, this paper presents risk assessment index system of transformer life cycle cost, applying matter-element model and extension analysis theory to quantify the qualitative indexes in order to assess the risk. Combined with an example, the paper quantifies the uncertain factors of power transformer life cycle cost management in order to build the life cycle cost risk assessment system. It realizes the risk rating of the transformer cost assessment, getting the key risk factors which affect transformer cost so that we can put forward targeted control strategies according to various risk factors in practical engineering.
