Problems solved by technology

[0009] The State Grid Development Department proposed measures to estimate the investment completion rate and entry cost based on the construction progress. In the process of "three rates", a whole set of three rate theoretical curve prediction models was proposed, which focused on improving the defects of the accuracy of the planned construction period. The predicted curve was updated and corrected according to the adjusted planned construction period, and the reasonable interval of the three rate deviations was subsequently carried out. However, due to the differences in various conditions (climate, manpower, construction costs, etc.) and the lack of pertinence for infrastructure projects in various places, the calculation of project weight coefficients has the greatest impact and is very large. limit its applicability

Abstract

The invention relates to a power distribution network infrastructure project investment statistical method. The method comprises the following steps of estimating monthly investment amount i based onmonthly investment percentages of historical similar projects in a local area; and calculating the engineering weight coefficient of each subsection based on the historical similar projects of the local area. The invention also relates to a power distribution network infrastructure project investment statistics deviation correction method. The method provided by the invention has good universalityand suits the actual condition..

Description

technical field [0001] The invention relates to a distribution network infrastructure project investment statistics and deviation correction method. Background technique [0002] The State Grid Corporation of China has put forward the work goal of "actively adapting to reform requirements, accelerating the realization of precise investment, and effectively improving the quality and efficiency of power grid development". In the current distribution network infrastructure project management process, there is a phenomenon that the funds issued by the monthly plan do not match the actual monthly capital expenditure. If the planned funds are higher than the actual capital expenditures, it will cause capital precipitation and increase in interest and other costs, which is not conducive to cost reduction; if the planned funds are less than the actual capital needs, it will cause problems such as abnormal construction. [0003] If the funds issued by the plan match or have little d...
