Due to the complexity of hybrid AC/DC characteristics

and the increasement of dispatching and control equipment power grid upgrading and the frequent file exchanges year by year

the data stacking redundancy is becoming increasing prominent. This paper combs the core content of the power grid dispatching and control duty data

puts forward the general principles and methods of data collation

and analyses the current situation of data management. Countermeasures and suggestions are finally proposed at the end of the paper.
