Electric power engineering project cost risk management method and management system

The invention discloses an electric power engineering project cost risk management method and management system, relates to the technical field of engineering cost, and predicts various parameters of a current project by constructing a big data model. And analyzing the comprehensive development data of the thermal power station project bid invitation project book. Local related reports are searched through big data, labor cost data are obtained, the current environment and market are comprehensively known, comprehensive development and labor cost data are classified and summarized through a data integration module, corresponding coefficients are obtained through a cost budgeting module and analysis budgeting, and a comprehensive development coefficient Kfxs is generated and associated with a labor cost coefficient Ygxs. And finally, the cost evaluation module generates an evaluation result by comparing historical data with the relationship between the Zjxs and a first evaluation threshold value Q, so that a p
