The present invention relates to an intelligent transformer substation process layer and spacing layer communication data playback method used for a dynamic model test. Compared with the prior art, the method solves the defect that the data playback can not be realized during the process of the dynamic model test, and comprises the following steps of generating a new file; configuring the file; generating a sequence; calculating the sending time; calculating the link occupation time; calculating the actual sending time; generating the file; and playing back the file. According to the present invention, the dynamic model test recording data saved by an electric system standard COMTRADE file is transformed into a pcap file containing a SV frame satisfying a DL/T860.92 standard and a GOOSE frame satisfying a DL/T860.8 standard, and the above pcap file is played back by a network tester, thereby realizing the simulation test of a process layer and a spacing layer.
