The invention relates to a distribution automation joint debugging platform for FTU terminal equipment. The distribution automation joint debugging platform for the FTU terminal equipment is characterized in that voltage and current output of an experimental device is spliced in the input end of a terminal strip; an FTU terminal is connected with the opposite end of the terminal strip through a special connecting wire; a remote control test board on a tester is connected with the input end of the terminal strip which is located in the same side of the voltage and current output; the FTU terminal equipment is provided with a network cable and a special connecting wire, the network cable led from the FTU terminal is in communication connection with a special debugging channel in a distribution automation host station system, and the test port in the FTU terminal is spliced in the end opposite to the end of the remote control test board connected with the terminal strip through a special connecting wire. The distribution automation joint debugging platform for the FTU terminal equipment plays roles of automatically locating a fault, automatically isolating a fault section, automatically restoring power supply for non-fault sections, automatically restoring a power supply mode before supplying power and the like, achieves topology analysis, load transfer, load forecasting, network reconstruction and other advanced applications, has real-time performance, authenticity and reliability and needs to precisely test and jointly debug each FTU terminal.
