Problems solved by technology

[0003] However, the current investment evaluation of distribution network projects is concentrated in the evaluation of a single index. The investment evaluation of distribution network projects lacks objective and reasonable quantitative basis and in-depth analysis, and cannot accurately reflect the investment status of distribution network, and it is difficult to provide data support for investment in distribution network.

[0056] Distribution Transformer Investment Evaluation Model Meets Constraints

[0057]

[0058]

[0059] In the formula, Y is the total score of distribution transformer investment, and Y i1 is the sub-item score of the distribution transformer evaluation index, k i1 is the weight of the sub-items of the distribution transformer evaluation index, α i2 Dimension score for distribution transformer evaluation, β i2 Dimension weights are evaluated for distribution transformers, i 1 is the sub-item number of the distribution transformer evaluation index, and i2 is the distribution transformer evaluation dimension number.

[0060] For example, the distribution transformer investment evaluation model includes four dimensions: implementation process, social benefits, economic benefits, and safety benefits. The index details in each dimension are shown in Table 1. Differenc...

Abstract

The invention discloses a power distribution network project investment evaluation method and system. Basic data related to power distribution network project investment is collected; data is carded,according to a preset dimension, a power distribution network project analysis comprehensive evaluation model is constructed, the sorted basic data is substituted into the power distribution network project analysis comprehensive evaluation model, and a power distribution network project investment evaluation result is calculated, so that the power distribution network investment condition can beaccurately reflected from comprehensive multi-dimensional data, and data support is provided for power distribution network investment.

Description

technical field [0001] The invention relates to the technical field of distribution network investment analysis, in particular to a distribution network project investment evaluation method and system. Background technique [0002] Distribution network is an important public infrastructure for national economic and social development. At present, domestic distribution network project investment evaluation focuses more on the safety and reliability of distribution network, and less attention is paid to project investment indicators, especially in recent years. The distribution network project has a lot of investment. After some distribution network equipment is put into production, the load rate and maximum load utilization hours are not high, the equipment is in a light no-load state, and the heavy overload of some equipment has not been effectively resolved. Therefore, it is necessary to project investment evaluation; [0003] However, the current investment evaluation of ...
