The invention discloses a general and quick access method for power distribution network operating data and power distribution data of an electric system. The method includes the following steps that (1) a general data access interface, a data coding and analyzing interface and a bottom layer data access interface are constructed on the basis of unified data coding; (2) the general data access interface is called to obtain a data coding set meeting query conditions; (3) the data coding and analyzing interface is called, wherein a coded value of each datum in the data coding set serves as input to call the data coding and analyzing interface; (4) the bottom layer data access interface is called; (5) a query result is returned according to an interface call relation, and general and quick access of data is completed. According to the general and quick access method for the power distribution network operating data and the power distribution data of the electric system, general and quick access of data is achieved on the basis of unified data coding and multiple interfaces.
