A state assessment method for distribution automation wireless public network communication system

Abstract

The invention discloses a state evaluation method of a wireless public network communication system for power distribution automation. The wireless public network communication system for power distribution automation includes a plurality of power distribution terminals, a wireless data transmission module connected to the power distribution terminal, and a wireless data transmission module The communication operation network, the public network router communicating with the operation network, the wireless network management system and the wireless server connected to the public network router, and the power distribution master station system connected to the wireless server, the state evaluation method specifically includes the following steps: 1) wireless state The information is processed once, and the state quantity of the wireless data transmission module is converted into event records and statistics, and the received analog data is displayed in real time; 2) The wireless state information is processed twice, from the event of the wireless state information Determine the current wireless status and the cause of the abnormality in the record; 3) If the wireless status is normal, score the communication delay. The present invention has the functions of rapid location of wireless faults, signal state evaluation of wireless health scoring, and the like.

Description

technical field [0001] The invention relates to the field of power distribution automation, in particular to a state evaluation method for a wireless public network communication system of power distribution automation. Background technique [0002] With the rapid development of communication technology, various communication methods such as optical fiber communication, public network wireless communication, and distribution line carrier communication have appeared in the distribution network. The communication mode between the distribution network master station and the distribution network automation terminal on the line is one of the key points in the development of the distribution network automation system communication. Due to the characteristics of many points, wide areas, and dispersal in distribution network communication, it is difficult to use only one communication method to solve the problem. Therefore, it is necessary to choose different combinations of communi...

Problems solved by technology

[0008] Generally speaking, the drive test system and the wireless signal automatic monitoring device only analyze and evaluate the quality of the wireless signal. The evaluation data can only indicate the quality of the communication on the wireless side. It is only one of the links in the wireless communication of the distribution network. The overall network communication structure of the distribution network has certain limitations when using it as a distribution network communication quality assessment, and whether the distribution network communication is abnormal is also closely related to the smoothness of the pre-router network and wireless server network; the wireless data transmission currently used in the distribution network The wireless network management system of the distribution network wireless communication module brought by the module manufacturer also has imperfections. This system is more used for account management. The information is very limited, and it is difficult to directly judge the cause of the abnormality through this information
