The invention discloses an automated testing device for a power distribution terminal. The automated testing device is characterized by comprising an OMAP module, an FPGA module, a display module used for man-machine interaction, wherein the OMAP module and the FPGA module communicate with each other through a data bus, the FPGA module is connected with a telemetering input testing interface and carries out processing on tasks at a telemetering input side, the OMAP module is respectively connected with a remote signaling input testing interface and a remote control input testing interface and carries out processing on tasks at a control side, and a standard model of the automated testing device is used for constructing a plurality of the power distribution terminals into a plurality of logical devices according to a modeling principle of an IEC61850 standard, so as to achieve function tests of the power distribution terminal. The automated testing device for the power distribution terminal solves the problems that the existing state grid typical design power distribution terminal is low in testing efficiency, the field maintenance workload is great and the like.
