The invention discloses an IEC61850-based power distribution terminal, namely a plug and play model configuration tool and a realization method of the IEC61850-based power distribution terminal. Through information interaction between a configuration software tool running in a subscriber's machine, a configuration software background running in the power distribution terminal and the distribution master station, a background program automatically generates a self-describing model based on the IEC61850 standard, which can be used for realizing plug and play of the power distribution terminal and the automatic on-line function of the power distribution terminal in the distribution master station system during the field deployment process, field installation, debugging and operation and maintenance of the power distribution terminal can be carried out conveniently; at the same time the realization method of the configuration tool is simple, the configuration of the field deployment terminal is effectively improved, the automatic on-line efficiency is improved, the time spent on debugging of databank corresponding of the distribution master station and the FTU and DTU on site of the power distribution terminal is shortened, and the great significance on debugging and maintaining of distributed and scattered distribution automation systems of the power distribution terminal systems in large quantities is further achieved.
