Method for correcting load flow calculation data error of database transfer power system

The invention discloses a method for correcting a load flow calculation data error of a database transfer power system. The method comprises the following steps: reading a rule base for describing a floating point type data format in a DSP load flow calculation data card; reading floating point type parameters in an SCADA database, which are processed into a basic form of DSP load flow calculation and analysis data, and storing the floating point type parameters as a preset data structure; mapping the data in the SCADA database with the format definition information of the rule base through the parameter name, and obtaining a specific floating-point number type corresponding to the parameter name; in combination with a processing rule of a DSP on a floating point number input format, classification matching is carried out according to positive and negative values of reference values in an SCADA database, integer digits and decimal digits, errors are corrected, and the highest-precision floating point type dat
