Cost Forecast of Overhead Transmission Line Based on BP Neural Network

摘要

In order to make accurate and reasonable estimate of the overhead transmission line cost, which will become the basis for the establishment of project and cost, it is required to select an appropriate estimation method. Considering the traditional estimation methods' shortcomings of higher subjective nature and low forecast accuracy, this paper is based on the BP neural network, making use of the computer resources and proposes a new method of estimation using the specifications and performance parameters of transmission lines as training samples. By comparing the predicted value and actual value, it demonstrates that BP neural network can accurately predict the cost of overhead transmission lines so that the workload can be greatly reduced.
