A system and method for analyzing abnormal communication of distribution network automation terminal

Abstract

The present invention proposes a distribution network automation terminal communication anomaly analysis system, including: several distribution network automation terminals, used to generate communication messages communicated with the distribution network automation master station; a collector, used to collect distribution network automation terminals generated Communication message information; the front-end server of the DMS system is used to store the communication message information transmitted by the collector, analyze and compare the communication message information, and generate a distribution network automation terminal communication abnormal work order; the distribution network intensive device, It is used to receive and display the abnormal communication work order of the distribution network automation terminal sent by the front-end server of the DMS system; the invention also proposes a communication abnormality analysis method of the distribution network automation terminal, which ensures that the staff can find the distribution network automation terminal with abnormal communication in time, The operation quality of the distribution network automation terminal equipment and the operation reliability of the distribution network are improved.

Description

technical field [0001] The present invention relates to the technical field of distribution network automation terminal communication analysis, and more specifically, to a distribution network automation terminal communication anomaly analysis system and method. Background technique [0002] With the continuous development of distribution network automation, the application of distribution network automation terminals in distribution networks in various regions is becoming more and more popular. Distribution network automation terminal refers to the general term for various feeder remote terminals, distribution transformer remote terminals, medium voltage monitoring units (distribution substations) and other equipment used in distribution network feeder circuits. Counting the online status of distribution network automation terminals in a region, judging whether a distribution network automation terminal is communicating normally, etc. are common statistical items in power d...

[0003] At present, whether the distribution network automation terminal communication is abnormal is found by judging whether the communication channel of the distribution network automation terminal is available. The method of judging whether the communication of distribution network automation terminals is normal or not by using the rate can not meet the needs of daily business of distribution network scheduling

Taking the Foshan area as an example, there are currently 13,000 distribution network automation terminals in operation. Calculated according to the channel availability rate, the online rate of the distribution network automation terminal communication channel in Foshan area is 94.07%. The situation still happens from time to time. When manually checking the channels and messages of the abnormal distribution network automation terminal, it may appear that the channel of the distribution network automation terminal is available, but the communication content between the terminal and the master station is abnormal, such as Frequent link resets, no response to the general call, etc. Therefore, the only way to troubleshoot such problems is to analyze the communication messages of the terminals. Manual analysis is not only extremely heavy and inefficient, but also cannot be performed on each distribution network automation terminal in the entire network. Real-time monitoring, troubleshooting and rectification of distribution network automation terminals cannot be carried out in time, which affects the operation quality of distribution network automation terminals
