Abstract：There are many uncertain factors in power grid engineering cost control. In order to improve the ability of power grid engineering cost control， a method of identifying the key factors of power grid engineering cost control based on analytic hierarchy process （AHP） is proposed. The multi-level parameter distribution model of power grid engineering cost control is constructed， the characteristic information fusion processing of power grid engineering cost control is carried out by using big data information fusion method， the correlation characteristic quantity of power grid engineering cost control is determined， the characteristic correlation model of power grid engineering cost is constructed by using autocorrelation feature analysis method， and the capital chain factor， material equipment factor and monetary policy are used to construct the characteristic correlation model of power grid engineering cost. The natural environment， financial financing and other factors are statistical variables， and the model is then built. The paste feature mapping model is used to analyze the quantitative characteristics of power grid engineering cost， and the analytic hierarchy process （AHP） is used to realize the quantitative recurrent analysis of the key factors of power grid engineering cost control， and the identification of the key factors of power grid engineering cost control is realized according to the results of quantitative recurrent analysis. The simulation results show that the accuracy of using this method is high to identify the key factors of power grid engineering cost control， and the cost and quality control efficiency of the project cost are better.
