Abstract

The invention provides an infrastructure substation project cost prediction method based on a neural network intelligent algorithm. The method is characterized by comprising the following steps of: collecting existing power transmission and transformation project final settlement data as a sample, preprocessing the sample data to form a data set, screening out a key factor set from an original factor library of the data set for further analysis, extracting feature parameters, and constructing a cost prediction model according to the feature parameters of a database, preprocessing the power transmission and transformation project data to be predicted, extracting characteristic parameters, and substituting the characteristic parameters into the cost prediction model to obtain the project cost. The accuracy and the rationality of investment plan arrangement are ensured, the company power grid asset transfer rate is improved, and important support is provided for company power transmissionand distribution price stability.

Description

technical field [0001] The invention relates to the field of project cost prediction of 110kV and above substation projects, in particular to a cost prediction method for infrastructure substation projects based on a neural network intelligent algorithm. Background technique [0002] In foreign countries, especially in Europe and the United States, a series of developed countries have started research on cost forecasting earlier, and the methods used are relatively traditional and classic. The research on the cost of engineering projects originated in the United Kingdom, and the British government with the background of the Royal Society of Surveyors proposed the construction cost information service system. [0003] Since the 1990s, with the development of computers, artificial intelligence technologies such as genetic algorithms and artificial neural networks have been widely used in establishing engineering cost estimation models. Expert system is also a kind of artifici...
