The Intelligent Model And Application Of Power Transmission Project Cost Analysis

China’s economic social development situation objectively requires Power Grid Corp to further improve the level of construction cost management and engineering cost analysis, so that can meet the needs of the reform and transformation. The existing method based on the comparation of settlement amount and approved budget estimates has been unable to meet the needs.So this article introduces intelligent analysis method and improves the theory of cost analysis and strengths the system construction based on the power engineering cost intelligent analysis model At the same time, empirical analysis of the transmission network in Sichuan Province about the power transmission project analysis, cost intelligent prediction and cost intelligent evaluation has strengthen the practicability of the theory. Firstly, identifies the power transmission project cost factors from multiple dimensions of whole process, natural and technical conditions, using principal component analysis and path analysis method to measure these factors. By factor analysis, gets the relationship between various factors and project cost. Then constructs transmission power project cost intelligent prediction mode based on clustering combination, and campares the model applicability, accuracy and efficiency. By power engineering cost intelligent prediction model based on clustering combination, gets higher estimation accuracy and improves the prediction efficiency. Finally, the intelligent power engineering cost evaluation model based on support vector machine is built. By this model, grasps the global nonlinear characteristic, simplifies the evaluation process of manual operation and improves the intelligence of the evaluation model.The study on the intelligent model and application of power transmission project cost analysis not only can make the cost analysis to be more effective, scientific and intelligent, but also can help electric power enterprises to control the project cost more effectively with a theoretical basis and reference.So this research has strong practical significance and application value.
