Problems solved by technology

The distribution network generally adopts closed-loop design and open-loop operation. The structure of the entire distribution network is huge and complex. Technical and economic experts generally evaluate it based on their own experience when analyzing the cost. There is a lack of a set of scientific, reasonable and effective evaluation standards, which cannot be very good. Controlling the investment of distribution network projects in a certain degree restricts the development of distribution network construction decision-making and project investment management in the direction of leanness, standardization and intelligence

Embodiment Construction

[0014] The auxiliary index analysis of distribution network engineering cost in the present invention includes the following contents:

[0015] (1) Trend Analysis

[0016] The trend analysis method refers to comparing the actual results with the historical data of the same parameters in the reports of different periods. The specific analysis methods include two methods of fixed ratio and ring ratio. The fixed ratio is based on a certain period, and all other periods are compared with the base of this period. The chain ratio is based on the previous period as the base, and the next period is compared with the base of the previous period.

[0017] (2) Index Analysis

[0018] The index analysis method is to use the index system to quantitatively analyze the fluctuation range, degree and absolute quantity of the comprehensive changes of the phenomenon affected by various factors.

[0019] (3) Sensitivity analysis

[0020] Sensitivity analysis is a method to study and analyze t...

Abstract

The invention discloses auxiliary index analysis for power distribution network engineering cost. The auxiliary index analysis comprises trend analysis, index analysis and sensitivity analysis. Assessment experts can be assisted to quickly, accurately and intelligently evaluate the reasonability of engineering cost; the review manner is innovated, and the review efficiency is improved. The problems that the design review measurement standard is unified and the workload of each professional reviewer is large are solved, the efficiency and quality of power distribution network engineering design review are greatly improved, and improvement and investment control for a power distribution network engineering design scheme are efficiently and accurately guided.

Description

technical field [0001] The invention relates to an auxiliary index analysis of distribution network engineering cost, which belongs to the field of power systems. Background technique [0002] With the continuous deepening of power system reform and the sustained and rapid growth of the national economy, as the scale of investment increases, the impact of project cost levels on the development of power grids is becoming more and more significant, and the cost of power grid projects has therefore attracted much attention. The distribution network generally adopts closed-loop design and open-loop operation. The entire distribution network structure is huge and complex. Technical and economic experts generally evaluate it based on their own experience when analyzing the cost. There is a lack of a set of scientific, reasonable and effective evaluation standards, which cannot be very good. Controlling distribution network project investment in a certain degree restricts the devel...
