Economic Benefit Post-evaluation for Technical Revamping of Power Grid Projects

On the basis of the variations of the technical revamping of the power grid projects with cross purposes ,and diverse contents is hard to put into practice the economic and efficiency analysis of the power grid projects. So a new project economic benefit post evaluation model of the technical revamping of the power grid project is presented based on the method of before and after comparison. A proper project economic benefit post evaluation criterion is introduced along with a theory of life cycle costs and a evaluation index system of the technical revamping of the power network projects is constructed. On the foundation of the theory of life cycle costs, the innovative economic benefit post evaluation model can provide reliable methods and criterion for the rationality analysis and the decision risk control and the economic benefit assessment of the technical revamping of the power grid projects.
