The invention discloses a power distribution terminal plug-and-play communication method based on an IEC 61850 standard, comprising that: a power distribution terminal transmits registration information to a main station terminal; the main station terminal receives and verifies registration information; if the registration information is inconsistent, a information model file is issued to the power distribution terminal according to the registration information or the information model filed is obtained through the power distribution terminal, so that the registration information received by the main station terminal is consistent with the registration information transmitted by the power distribution terminal; the main station terminal parses the information model file into a communication point table according to the corresponding mapping relation; the power distribution terminal transmits real-time operation information of a power distribution network to the main station terminal according to the local information model;and the main station terminal receives real-time operation information of the power distribution network and controls the power distribution terminal through orders. The invention, through the interaction of information models, realizes the self-description of the power distribution terminal and automatic recognition and automatic analysis performed on the function points of the power distribution terminal by the main station terminal so as to achieve the plug-and-play communication effect of the power distribution terminal when the power distribution terminal accesses the network, modifies configuration, updates and maintains the system.
