Abstract

The invention discloses a power distribution terminal system based on the IEC 61850 and realizing a plug and play mechanism. The power distribution terminal system is realized through the following steps that (1) a power distribution terminal is connected with a power distribution master station, and automatically sends registration information to the power distribution master station; (2) information contrast is conducted on the power distribution terminal and the power distribution master station; (3) a plug and play self-describing modeling module is run between the power distribution terminal and the power distribution master station; (4), the power distribution master station receives information collected by the power distribution terminal and controls power distribution network equipment. According to the power distribution terminal system, the plug and play function of the power distribution terminal is realized by the self-describing modeling module based on the IEC 61850 standard through plug and play information interaction, the automatic on-line function of the power distribution terminal at the power distribution master station system is achieved during on-site deployment, the power distribution terminal can be installed, debugged, operated and maintained conveniently on site, in this way, the time of conducting spotting and other debugging operations on the master station and an FDU and a DTU of the power distribution terminal can be greatly shortened, human errors can be reduced, and reliability is improved. The power distribution terminal system has important significance in debugging and maintenance of a power distribution automation system with a large number of power distribution terminal systems distributed quite dispersively.

Description

Technical field [0001] A power distribution terminal system, especially a power distribution terminal system that implements a plug-and-play mechanism. Background technique [0002] As the last link of the power transmission and distribution system, the distribution network is closely related to the quality and reliability of power supply and utilization. Smart distribution network is an important part of the construction of smart grid. It integrates modern computer technology and communication network technology to monitor, coordinate and control the equipment on the distribution network in real time, which is to improve the quality of power supply. An important means for reliability, expansion of power supply capacity, and efficient and economical operation of the distribution network. An important feature of the distribution network is the wide range of terminal equipment points, which leads to high costs for the construction and maintenance of distribution network automation...
