Power grid capital construction project optimization method and system based on life cycle cost

Abstract

The invention discloses a power grid infrastructure project optimization method based on life cycle cost. The method comprises the following steps: setting a plurality of alternative construction schemes for a power grid infrastructure project according to a construction target; acquiring a plurality of sample data sets in one-to-one correspondence with the plurality of alternative construction schemes, wherein each sample data set comprises cost data, economic data and technical data of the power grid infrastructure project in the whole life cycle; performing conversion on the cost data in each sample data set through a preset LCC model to obtain a corresponding life cycle cost; comprehensive analysis is carried out on each whole life cycle cost and corresponding economic data and technical data; and according to a construction scheme decision rule and the plurality of sample analysis results, identifying a priority construction scheme from the plurality of alternative construction schemes for constructing a power grid capital construction project. According to the design, it is guaranteed that the priority construction scheme is provided for the power grid infrastructure project more accurately and reasonably, and the method has simplicity, reliability and practicability.

Description

technical field [0001] The invention relates to the technical field of power grid planning, and in particular, to a method and system for optimizing power grid infrastructure projects based on full life cycle cost. Background technique [0002] The whole life cycle usually refers to the entire life stage of a project or product from design to scrap, and the life cycle cost (LCC) usually refers to the total cost of the project or product in the entire life cycle. Mathematical model used to measure life cycle cost. [0003] Power projects are the basis of power grid planning, construction and development. They have the attributes of being affected by various factors such as cost, economy, technology and environment in the future. It is very complicated to provide a more optimized construction plan for power projects. and difficulty. Usually, the construction scheme only needs to consider the necessity and feasibility of the power project, but lack of consideration of the who...
