A dynamic early warning identification method and system for power grid infrastructure projects

Abstract

The invention relates to a power grid capital construction project dynamic early warning identification method and system, and the method comprises the following steps: analyzing the current situationof power grid capital construction project dynamic early warning, and building a power grid capital construction project multi-dimensional target time sequence prediction model; establishing a powergrid capital construction project early warning index library, and constructing a power grid capital construction project three-level key early warning index library and an index influence structure diagram by utilizing the interpretation structure model; collecting engineering data of the power grid capital construction project to be evaluated, drawing a dynamic early warning curve of the power grid capital construction project, and determining a dynamic early warning threshold value of the power grid capital construction project; and based on a multi-dimensional target time sequence prediction model and mapping and membership relationships between different levels of the dynamic early warning curve and the three-level key early warning index, constructing a top-down or bottom-up bilateral linkage deviation checking mechanism, and carrying out dynamic early warning on the power grid infrastructure project. The method can be widely applied to the field of power grid capital construction project dynamic early warning.

Description

technical field [0001] The invention relates to the field of grid infrastructure project management, in particular to a dynamic early warning identification method and system for grid infrastructure projects. Background technique [0002] Power grid infrastructure projects refer to power grid construction projects with the main goal of completing new construction, expansion, and other expansion of power transmission and distribution capabilities in accordance with certain project rules and procedures and a certain amount of investment. The project has a series of notable characteristics such as huge investment, high proportion of equipment costs, low investment income, difficult land acquisition, high technical difficulty, many participants, complex organizational relationships, multiple points and long lines, and many external factors. Therefore, it is decided The implementation of power grid construction projects will be affected by many factors. [0003] Due to the large...
