System and method for data communication between power distribution master station system and power distribution terminal

Abstract

The invention discloses a system for data communication between a power distribution master station system and a power distribution terminal. The system comprises at least one wireless data collection terminal and an access point network (APN) transmission network, wherein the wireless data collection terminals are connected with the power distribution terminal one by on and used for collecting electric power information of grid primary equipment in the corresponding power distribution terminal, and transmitting the collected electric power information to a mobile communication network through a preset communication protocol, or transmitting command data received through the mobile communication network to the corresponding powder distribution terminal; and the APN transmission network is used for receiving the electric power information which is transmitted to the mobile communication network from each wireless data collection terminal according to the preset communication protocol and transmitting the electric powder information to the master station system or forwarding the command data transmitted by the master station system to the corresponding wireless data collection terminal through the mobile communication network. The invention also discloses a corresponding method for data communication between the distribution master station system and the distribution terminal. The system and method provided by the invention ensure the security and accuracy of data transmission and great reduction of communication cost.

Description

technical field [0001] The invention relates to the field of power system distribution automation, in particular to a data communication system and method between a power distribution master station system and a power distribution terminal. Background technique [0002] The basis of the implementation of the distribution automation system is to monitor and control the primary equipment of the distribution network, and the distribution network itself has the characteristics of wide distribution, large number of equipment, and complex communication conditions in the geographical location. At present, the terminal data collection work of the distribution automation system is mainly realized by laying the power optical fiber private network, and some of them use the power carrier communication method to realize the data collection work of the primary equipment of the distribution network. [0003] The optical fiber communication widely used in the prior art has the characteristi...

AI Technical Summary

Problems solved by technology

[0003] The optical fiber communication widely used in the prior art has the characteristics of high reliability, high security, and high communication quality. However, this networking method also has the problems of high investment and difficult expansion, especially for the widely distributed distribution network. , and the characteristics of frequent transformation make the private network communication cost of electric optical fiber increase

For power carrier communication, although its communication cost is low, due to its low communication quality, it is less and less used in practical applications.
