efficiency of the review are this paper the big data preprocessing method is used to analyze the
，
data of large⁃scale power grid project and the technical and economic evaluation of power grid planning
，
and fixed assets investment projects is carried out as well as the data processing work related to the
，
planning project management information taking guangzhou power supply bureau as an
，
example an intelligent evaluation and analysis system of investment cost data is developed and
，
designed which is suitable for the scope of the power supply bureau. It is responsible for the data
