Information network based on low-voltage distribution network

Abstract

An information network based on a low-voltage distribution network is of a tree-shaped structure, and can be divided into the following different levels of network segments including the distribution transformer level (tree root), the yard level, the building level, the storey level, the household level, the room level, and the device level (tea leaves) from the root to the leaves, wherein according to the network segment of each level, upper nodes are connected with lower nodes through cable branches, a distribution transformer serves as the root node to induce the network, electric devices serve as leaf nodes to end the network, electrical information generated in the network such as voltage, current, power factors and harmonic waves are automatically collected and processed on line in the nodes of the network segments of all the levels, the nodes serve as information nodes and sources of distributed information of the network, information is transmitted vertically on the basis of branch cables in the network segments, the cables serve as physical channels of the information network, the low-voltage distribution network is informationized to serve as the information network as well, and the power supply and consumption process of the distribution network is informationized so that people can carry out on-line monitoring and management on the power supply situation through the low-voltage distribution network in the power utilization process of daily production and life.

Description

technical field [0001] The patent of the present invention belongs to the field of information network technology and electric technology, and more specifically makes the low-voltage power distribution network and the power supply and consumption process on the network online informatization and makes power saving intelligent. The title of the invention is hereinafter abbreviated as "Low-Voltage Power Distribution Information Network". Background technique [0002] According to my country's current power supply system, the power grid is distributed from high-voltage power transmission, medium-voltage power transmission and distribution to low-voltage power distribution, and then the medium-voltage 10KV power grid supplies power to the low-voltage distribution network through distribution transformers, so that one distribution transformer drives a set of The low-voltage power distribution network supplies power to various users in a distribution transformer area.
