An automatic detection platform and a detection method for distribution automation terminals are provided. The detection platform includes a communication module, and a control module, an informationencryption module, a signal source 1, a standard clock module and a signal source 2 connected with the communication module, and a standard meter connected with the control module and the signal source 1. The automatic detection method for distribution automation terminals includes the following steps: according to the detection information of a pre-established detected distribution automation terminal, configuring a detection case of the detected distribution automation terminal, forming a control instruction in the detection process, and generating a detection signal; and carrying out calculation, comparative analysis and evaluation according to a received response signal of the detected distribution automation terminal and the operation condition of the detection platform. The function,performance and protocol consistency of multiple distribution automation terminals can be detected automatically and simultaneously, and the function of fault detecting and handling between multipledistribution automation terminals can be detected.
