Abstract

The invention relates to an intelligent power distribution network and power-consumption real-time monitoring and managing system, which comprises an electric power user centralized-control terminal device, a data transmission device and a system monitoring server; the electric power user centralized-control terminal device is used for receiving power consumption information of an electric power user monitoring device and for outputting a signal for controlling the user monitoring device; the data transmission device is connected downwards with at least one electric power user centralized-user terminal device and is connected upwards with the system monitoring server through a cabled network. The system has the advantages that: instant interaction and information communication between the electric power enterprise and the users are realized, and the information interaction and communication inside the electric power enterprise are realized; emergent item protection of electric network and devices is realized; and the system can instantly collect the running data of all circuits and devices in the electric distribution network, can collect the state data of the device, and can collect the data of measuring devices, running data of communication transmission system and the state data, image data, audio data and video data of the transmission devices.

Description

technical field [0001] The invention relates to intelligent, informatized and automatic real-time monitoring and management of power grid users, in particular to an intelligent distribution network and a real-time monitoring and management system for power consumption. Background technique [0002] As the terminal system of the power industry, the distribution network includes distribution lines, distribution equipment, line switchgear, operation monitoring equipment, distribution transformers, distributed green energy devices and all power users. [0003] It is imperative to realize comprehensive, intelligent and real-time monitoring and management of distribution network. The existing partial and single-function distribution network automation systems, such as: remote meter reading system, load management system, power consumption information collection system, etc., can no longer meet the needs of modern monitoring and management of distribution network. Intelligent real...
