Transmission engineering is an important part of electric power infrastructure engineering, accurate cost prediction can effectively control the project budget and promote the fine management of electric power enterprises. However, the influence factors of transmission engineering cost are complex, and the traditional prediction method cannot meet the requirements of network refinement development. In this paper, the importance of random forest features is used to extract the key influencing factors, and the grid search method is used to select the optimal random forest parameters and train the random forest model. Finally, the random forest model is tested by actual engineering data and compared with the prediction results of the supporting vector machine model. The results show that the relative error of the stochastic forest model is low, which provides a certain reference value for the cost budget of transmission engineering.
