Establishment of technological economic indicator comprehensive database in power transmission and transformation

Abstract

Establishment of a technological economic indicator comprehensive database in power transmission and transformation comprises the steps of performing basic data normalization and standardization; performing fabrication cost analysis evaluation index system researching; establishing a fabrication cost analysis model; realizing fabrication cost analysis normalization, realizing quick extraction and automatic checking gathering of the economic indicators, forming the technological economic indicator database, and furthermore realizing fabrication cost analysis normalization. According to the established technological economic indicator comprehensive database, analysis for the weight of each component in engineering fabrication cost is realized, and a theoretical support is supplied for engineering fabrication cost decision control and trend analysis. Furthermore connection between a platform according to the invention and information system databases inside and outside an enterprise is realized so that economic data can be efficiently utilized. A unified technological economic management standard is realized. Cost saving and scientization in technological economic management are promoted. Information efficiency in a power engineering fabrication cost analysis field is improved.

Description

technical field [0001] The invention relates to the establishment of a comprehensive library of technical and economic indicators for power transmission and transformation projects, belonging to the field of electric power systems. Background technique [0002] At present, in the process of cost management and technical and economic analysis of power transmission and transformation projects, engineering technical and economic indicators are reflected differently in different power enterprise departments. In the hands of personnel, it is very difficult to collect engineering technical and economic indicators and data, and the data utilization efficiency is low, which affects the comprehensive engineering cost analysis; at the same time, the establishment of technical and economic cost data related to power engineering estimation, budgetary estimates, bidding, and settlement is incomplete, and there is no unified The platform collects and summarizes a full amount of technical ...

[0002] At present, in the process of cost management and technical and economic analysis of power transmission and transformation projects, engineering technical and economic indicators are reflected differently in different power enterprise departments. In the hands of personnel, it is very difficult to collect engineering technical and economic indicators and data, and the data utilization efficiency is low, which affects the comprehensive engineering cost analysis; at the same time, the establishment of technical and economic cost data related to power engineering estimation, budgetary estimates, bidding, and settlement is incomplete, and there is no unified The platform collects and summarizes a full amount of technical and economic indicators; in the process of analyzing and collecting technical and economic indicators, due to inconsistent data interfaces, the phenomenon of data islands is common, and it is difficult for most technical and economic indicators to form data integration and sharing. The repeated reference of the technical and economic index data has created certain obstacles to the overall technical and economic cost process control and trend analysis of power transmission and transformation projects.
