A digitized recording playback method comprises the two parts of matching of a recording file and an SCL file and synchronous recording playback. Matching of the recording file and the SCL file refers to the steps of matching a recording data channel and information in the SCL file through a matching tool, generating SV and GOOSE message template information, respectively forming a sampling value and a switching value in a wave record into the data format suitable for playback of a simulation system to achieve synchronous output of the sampling value and the switching value in a fault wave record. The synchronous recording playback refers to the steps of conducting difference value fitting on SV data through an FPGA in the simulation system according to wave record frequency, wave record data, SV and the GOOSE template information stored in the simulation system, a standard SV message is obtained, and synchronous output of the SV message and a GOOSE message is achieved by designing a delay module. The digitized recording playback method is mainly applied to the field of simulation tests of a power system, a new and easy testing method is provided for accident recall and problem analysis.
