Investment scheme evaluation and correction system for power grid investment project and operation method of investment scheme evaluation and correction system

The invention relates to an investment scheme evaluation and correction system for a power grid investment project, which comprises an information acquisition unit, an income estimation unit, an evaluation and analysis unit, a scheme correction unit and a project supervision unit, the profit estimation unit is used for estimating profit according to the current actual expenditure of the project, the evaluation analysis unit is used for carrying out risk evaluation through a project risk evaluation model and determining the most important risk factor and risk probability, and the scheme correction unit is used for carrying out investment scheme optimization correction in combination with a risk evaluation result, the profit and a completion degree result. The project supervision unit is used for collecting node data in real time in the project construction process and sending the data to the information acquisition unit when it is judged that the change of the data is inconsistent with the data in the optimize
