At present, most of the methods of data integrity evaluation operate on data directly, which have a low efficiency to evaluate the huge amount of smart grid data and also can not realize quantitative evaluation objectively. This paper realizes smart grid information integration based on IEC 61970, and then according to the definition of the integrity, builds an automation model on the smart grid data, and gives a quantitative evaluation model for data integrity which needs not operate on the data directly. By analyzing and quantifying the indexes of integrity, the data integrity quantitative evaluation models aiming at different security states in smart grid are given. At last, the model is proved feasible by an example.
