Problems solved by technology

The disadvantage of this method is that the filtering process in the method is not systematically screened as a whole, and there are problems of missing key influencing factors and interference of non-key influencing factors
The disadvantages of this method are: due to the different dimensions of the index data units in the initial data set, the order of magnitude is not uniform, the quantitative and qualitative indicators are mixed, and the index levels are chaotic.
If the unprocessed data is directly used for analysis, the accuracy of the conclusion is difficult to guarantee

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] The invention discloses a method for evaluating the cost of a grid project, which includes the following four steps,

[0052] Step 1. Sort out and normalize the data of influencing factors in the power grid project cost corresponding to the new technology situation primitive, and construct a sample database, which specifically includes the following steps,

[0053] 1.1 Collect the cost data of 35kV-500kV power grid projects that have been completed and put into operation in the past five years under the new technology situation, and sort out the data of influencing factors that constitute the cost of power grid projects from two aspects of substation engineering and line engineering to establish an original database; the influencing factors include substation engineering Influencing factors and influencing factors of line engineering. Influencing...

Abstract

The invention belongs to the field of power grid engineering cost analysis. The invention relates to a power grid project cost assessment method. The method comprises the following steps: sorting influence factor data in power grid engineering cost corresponding to a new technical situation primitive, and carrying out normalization processing; Construction of a sample database, screening key influence factors of the power grid project cost in a sample database based on a principal component analysis method, establishing an explanation structure model of the influence factors of the cost project, constructing a key influence factor system of the power grid project cost based on the explanation structure model, calculating influence weights of the key influence factors by adopting an analytic hierarchy process, and sequencing. According to the method, before principal component analysis is carried out on the power grid project cost data, normalization processing is carried out on the historical project data, initial data are preprocessed, and a guarantee is provided for the accuracy of follow-up data analysis.

Description

technical field [0001] The invention belongs to the field of grid engineering cost analysis, in particular to a grid engineering cost evaluation method. Background technique [0002] In recent years, with the integration of new technologies such as artificial intelligence (AI), big data analysis, advanced sensor technology, intelligent integration technology, and green energy-saving technology with traditional power transmission and distribution systems, new technologies, new equipment, and new applications for power grid construction continue to emerge. It meets the needs of green energy development and ensures the safe, reliable and economical operation of the power system. In the modular construction of smart substations, mechanized construction, VAT reform, construction of urban underground comprehensive pipe corridors, preliminary work fees for electric power construction projects and other professional service fees, indoor substations or combined electrical devices can...
