The invention relates to a construction period prediction method and device for a power transmission and transformation project, which belongs to the technical field of power transmission and transformation projects, and solves the problems that the existing power transmission and transformation projects have insufficient progress historical data application level and insufficient progress control information level. The method includes: collecting raw data of multiple historical power transmission and transformation projects and preprocessing the raw data, wherein the raw data includes construction scale parameters and basic characteristic parameters; using multivariate statistics based on the raw data and the construction period corresponding to the raw data Regression method for analysis and calculation and use of principal component analysis and principal factor analysis methods to reduce the amount of original data and obtain historical progress data of multiple historical power transmission and transformation projects; and use the original data and the construction period corresponding to the original data to obtain A neural network prediction model, and obtain the predicted construction period of the power transmission and transformation project to be predicted through the neural network prediction model. It can predict the construction period of power transmission and transformation projects.
Description
technical field [0001] The invention relates to the technical field of power transmission and transformation projects, in particular to a construction period prediction method and device for a power transmission and transformation project. Background technique [0002] As a core business of the company, power grid construction is an important foundation for realizing the development goals of the power grid company. Therefore, strengthening investment in power infrastructure and accelerating transformation and development have put forward higher requirements for infrastructure control. [0003] The existing power transmission and transformation projects have the practical problems of insufficient application level of progress historical data and progress control informatization. In the process of preparing, real-time tracking and progress evaluation of the power transmission and transformation project schedule, the expert experience of the schedule controller is generally us...
