Cost control method for power grid technical improvement project

Abstract

The invention relates to a cost control method for a power grid technical improvement project. The method comprises the steps of screening estimation stage and settlement stage data corresponding to different professional projects from historical technical improvement project data after project completion settlement approval is completed; calculating to obtain balance data and balance change ratescorresponding to different professional projects, contribution levels of subitem expenses corresponding to different professional projects to the balance change rates, and balance data and balance change rates corresponding to the subitem expenses in different professional projects; then determining professional engineering with the balance change rate exceeding a balance threshold value and sub-item cost with the contribution level of the professional engineering to the balance change rate exceeding a contribution threshold value; and carrying out valuation control on the investment amount of the technical improvement project in corresponding professional engineering and sub-item expenses. Compared with the prior art, the invention has the advantages that the estimation stage data and the settlement stage data in the historical project data are compared and calculated, so that the subsequent targeted cost control can be ensured, and the difference between the investment and the actual cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cost management and control of technical renovation projects, in particular to a cost control method for technical renovation projects of power grids. Background technique [0002] With the development of the power grid becoming more and more perfect, the requirements for the safety and reliability of the power grid are also constantly increasing. Therefore, it is necessary to promote the technical transformation project of the power grid. Technical transformation refers to the use of mature and applicable advanced technologies, equipment, processes and materials at home and abroad. With the aim of improving production performance, enhancing its stability, safety, reliability, and economy, the existing production equipment, facilities, and supporting auxiliary facilities are perfected, matched or overall updated. [0003] As an important link in the operation and maintenance management of the power grid, ...

Problems solved by technology

At present, the cost control of technical transformation projects only puts forward suggestions on the whole process management of technical transformation projects from the perspective of process management, or systematically sorts out and analyzes the factors affecting the cost of technical transformation projects in regional power grids, and studies the post-evaluation of power grid technical transformation projects method and its index system, but these methods cannot effectively control the subsequent cost management, resulting in a large difference between the investment and the actual cost of the technical transformation project, which is not conducive to the development of the technical transformation project of the power grid
