Method and device of transmitting communication information in communication system of power distribution network

Abstract

The invention discloses a method and a device of transmitting communication information in a communication system of a power distribution network. In the communication system of the power distribution network, a premises network gateway is arranged between an access network and a premises network, after the premises network gateway receives a short data packet transmitted by the premises network, and the short data packet is identified corresponding to a premises network identifier, the short data packet is packaged in a data frame and is transmitted to the access network; after the premises network gateway receives the data frame carrying the short data packet adopting the premises network identifier from the access network, the short data packet is obtained through analysis and is transmitted to the premises network corresponding to the premises network identifier. In a process of transmitting the communication information, short datum, which are from different premises networks or reach different premises networks, are identified by adopting the premises network identifier, so that the speed of analyzing the short data packet is accelerated, thus the problem of multiple access is solved and the rate of polymerization of the communication information is improved.

Description

technical field [0001] The invention relates to the communication technology of distribution network, in particular to a method and device for transmitting communication information in the communication system of distribution network. Background technique [0002] Ensuring energy security and coping with global climate change are major challenges facing all mankind. To deal with this serious challenge, the networking of smart distribution network is proposed in the power system. The smart distribution network uses a sound two-way communication, advanced sensors and a distributed computer power transmission and distribution network. Its purpose is to improve the efficiency of power transmission and use, and improve the reliability and security of the power grid. [0003] The communication system of the distribution network is an important part of the smart distribution network and the basic condition for realizing the smart distribution network. The goal of the communicatio...

Problems solved by technology

[0012] The communication system of the distribution network can use the communication methods in Table 2 for network communication. However, the current communication system of the distribution network lacks a unified network planning. No matter which of the above communication methods is used, there will be the following various The problem:

[0015] Third, in terms of technical application, the communication methods adopted by the intelligent power distribution network in different regions are different, and some business applications such as meter reading, load control and distribution transformer monitoring use a large number of wireless private network methods, lacking unified planning and design; power distribution When the communication system of the network adopts optical fiber communication, it basically adopts the telecom level, and some functional features cannot meet the special requirements of electric power

[0018] However, there are two problems in using a heterogeneous network architecture to form a hybrid network as a communication system for a smart distribution network: First, there are many types of resident networks where user sites are located, such as 485 bus networks, ZigBee networks, or WiFi networks, etc. The communication protocols adopted by each type of resident network are different, so the communication master station of the smart distribution network cannot identify different user sites in different types of resident networks

That is, the multi-access problem cannot be solved in the communication system of the smart distribution network; secondly, due to the large number of user sites and the large amount of communication information sent to the communication master station of the smart distribution network, the communication of the smart distribution network The rate of real-time analysis of communication information by the master station is difficult to meet the needs of user sites, that is, the communication information aggregation rate of the communication system of the smart distribution network cannot meet the needs of user sites
