Abstract

The invention relates to the technical field of power system technical analysis, and discloses a method for calculating cost-benefit ratio of a power distribution network planning scheme, which comprises the following steps: step 1, constructing a quantifiable power distribution network line full life cycle cost model; step 2, carrying out cost analysis and investment type classification prediction on a power distribution network line; and step 3, analyzing the return rate of the power distribution network line. According to the method for calculating the cost-benefit ratio of the power distribution network planning scheme, an applicable power distribution network line full-life-cycle cost model is established, and cost analysis, investment type classification prediction and power distribution network line return rate analysis are performed on a power distribution network line through the method, so that cost-benefit comparison of the power distribution network planning scheme is realized; the technical and economic analysis level of power distribution network planning is improved, the scientificity and rationality of power distribution network planning are improved, and effective reference and data support are provided for the cost effectiveness of a power distribution network planning scheme.

Description

technical field [0001] The invention relates to the technical field of power system technical analysis, in particular to a method for calculating the cost-benefit ratio of a distribution network planning scheme. Background technique [0002] The investment in distribution network construction is increasing year by year, and the pace of investment in distribution network construction is accelerating. Effective and comprehensive comparison and selection of distribution network planning projects will be the basis for decision-making in power grid planning and construction. However, in the decision-making method of power grid investment and construction, it mainly focuses on the economic operation and management research of the power grid, the safety research of the power grid operation and the multi-objective power grid planning problem, and lacks the calculation method of the cost-benefit ratio of the distribution network planning scheme. Contents of the invention [0003] (...
