Abstract

In order to improve the efficiency of fund allocation for power grid asset technical transformation projects and promote the transformation results of power grid over-aged assets into the cost supervision and audit asset system, by establishing the dynamic programming model of partial technical transformation year by year, this paper studies the investment decision-making of differentiated technical transformation of over-aged assets, and determines the financial depreciation life after technical transformation combined with the comprehensive evaluation model of equipment health. The weighted average service life is introduced to improve the accuracy of the model results, and based on the revised weighted average of the remaining service life, selects the optimal financial depreciation life. Through a case study, it is proved that the year-on-year partial technical transformation can effectively extend the financial depreciation life of assets, the model can determine the optimal investment for technical transformation, and effectively guide the year-on-year partial technical transformation of assets of power grid enterprises, so as to achieve the goal of effectively using project investment.
