Embodiment Construction

[0042] This embodiment provides a method for evaluating the cost of a power transmission and transformation project based on spatiotemporal big data, the steps of which are as follows:

[0043] 1. Obtain time-related big data that affects the cost of power transmission and transformation projects, which is used to: input time characteristics for the establishment of power transmission and transformation project cost evaluation models. It specifically includes two aspects of data, one is the characteristic parameters and cost of power transmission at each time, including the unit price information of wires, ground wires, towers, insulators, pull wires, fittings, etc. that include purchase time information; the other is the information of each substation at the same time Characteristic parameters and substation cost data, including voltage level, intelligent or not, unit price of main transformer, single capacity of main transformer, quantity of main transformer, length of contro...

Abstract

The invention discloses a power transmission and transformation project cost evaluation method based on time-space big data. The influence factors of a power transmission and transformation project cost are numerous; and along with the appearance of new materials, new processes and new technologies, and the continuous change of the labor cost, the power transmission and transformation project costis continuously changed, so that an existing cost evaluation model cannot completely adapt to the change. The evaluation method comprises the following steps of 1) acquiring time-related big data influencing the power transmission and transformation project cost; 2) acquiring terrain space big data influencing the power transmission and transformation project cost; 3), building a power transmission and transformation project cost evaluation model taking the time-related big data and the terrain space big data as input characteristics; and 4) evaluating the current power transmission and transformation project cost by utilizing the built model. The method is used for performing cost evaluation on a power transmission and transformation project, and is particularly used for cost evaluationof a to-be-constructed project; a relatively good power transmission and transformation project cost evaluation result is obtained; and a reference is provided for power transmission and transformation project construction and cost management and control.

Description

technical field [0001] The invention belongs to the field of cost evaluation of power transmission and transformation projects, in particular to a method for cost evaluation of power transmission and transformation projects based on spatiotemporal big data. Background technique [0002] With the development of society and economy, the scale of the power grid continues to expand, and power companies continue to increase investment in power infrastructure and power transformation projects. The annual investment in power transmission and transformation projects is relatively large and the scale is relatively large. In order to improve the economic benefits of power transmission and transformation project construction, it is necessary to conduct a reasonable cost assessment of the project to be built, so as to provide strong support for the investment cost control and cost optimization of each construction unit. The main significance of studying the cost evaluation of power tran...
