Establishment of historical power grid typical engineering resource database

Abstract

The invention discloses an establishment of a historical power grid typical engineering resource database includes collecting historical engineering data, state grid general engineering costs and Electric Power Planning & Engineering Institute quota data, constructing a critical parameter library according to an engineering type, building a scientific and reasonable engineering cost contrastive analysis model by means of informatization, and realizing an intellectualized contrastive analysis for the engineering costs in order to assist the development of a techno-economics assessment. The application of the invention provides a support for an engineering cost management and control analysis. The invention has the advantages of establishing general engineering cost, costs of each engineering phase and costs of engineering with the same scale and similar type to assist comparative censor through an engineering cost database according to an engineering cost management requirement, carrying out engineering cost analysis, concluding rules and experience and providing the basic data reference and support for a subsequent engineering cost job, making full use of data mining technology and depending on the huge engineering cost database.

Description

technical field [0001] The invention relates to the establishment of a typical resource library of historical power grid engineering, and belongs to the field of electric power technology. Background technique [0002] In the current project design process, after the designer completes the drawing work of the professional, he summarizes and sorts out the various materials and equipment, forms a "material list" and submits it to the cost professional, and the technical and economic personnel form it according to the material list and in accordance with the budgetary preparation norms Project cost, this working mode makes technical and economic personnel put a lot of energy into judging the quota and the selection of materials. Under the background of heavy construction tasks and tight schedule of power grid project, it is difficult to ensure that there is enough time to check the estimated budget. Quality, to a certain extent, restricts the development process of power grid e...

Problems solved by technology

The difficulty of digitizing the cost major lies in: the design major can realize the virtual visualization of design products through digitalization; unlike the design major, the cost (or investment) of engineering (or equipment) does not have a conventional expression in the three-dimensional dimension. Therefore, restricted by the form of expression, the digitalization of the cost profession has not been able to open up a broad situation
