Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention provides a plug-and-play communication method for power distribution terminals based on the IEC61850 standard, such as figure 1 As shown, it specifically includes the following steps: the power distribution terminal sends registration information to the master station; the master station receives the registration information and verifies the registration information; if the registration information is consistent, the master station communicates with the power distribution terminal in real time; if the registration If the information does not match, the information model file (hereinafter referred to as the information model file) formed by IEC61850 information model modeling will be issued to the power distribution terminal according to the actual situation of the registration information, or the informatio...

Abstract

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.

Description

technical field [0001] The invention relates to a communication method for a power distribution terminal, in particular to a plug-and-play communication method for a power distribution terminal based on the IEC61850 standard, and belongs to the technical field of power distribution automation. Background technique [0002] Distribution terminal is a general term for various remote monitoring and control units installed on the distribution network site, mainly including feeder terminals, station terminals, distribution transformer terminals, etc. Its functions mainly include: data acquisition, control, data transmission, maintenance, time synchronization, sequence of events recording (SOE), feeder fault diagnosis, single-phase grounding detection, primary reclosing, etc. [0003] The distribution terminal is a necessary equipment for the construction of distribution automation, and its communication network with the main station system of distribution automation is also a nec...
