Problems solved by technology

[0003] With the continuous improvement of the practical level of the distribution automation system, the number of distribution automation terminals installed on the 10kV line continues to grow rapidly. Due to reasons such as the main station equipment, network communication, encryption chips, and the terminal itself, some or a large area of ​​the terminal is offline ;
[0004] At present, it takes too long to check the reason why the terminal is offline. During the detection process, the online rate index of the terminal will drop, the three remote functions will fail, and the fault location will be inaccurate. This will seriously affect the speed of field equipment elimination, line fault handling, and distribution network operation. Status monitoring, so quickly checking the cause of terminal offline is of great significance to reduce the time of equipment shortage elimination, reduce the power outage time of users, and improve the intelligent operation level of distribution network

Embodiment 1

[0032] Such as figure 1 As shown, this embodiment provides an offline detection method for a power distribution terminal, including:

[0033] Periodically detect the startup status of the encryption machine, front-end server and acquisition server;

[0034] Periodically check the encryption, decryption and authentication status of the encryption machine;

[0035] Periodically detect the heartbeat status between the front-end server and the collection server;

[0036] Periodic detection is based on the isolation status between the front-end server and the collection server;

[0037] The detection thread is set, and the detection results of the above states are judged in turn to obtain the offline detection results and offline reasons of the power distribution terminal.

[0038] In this embodiment, the reasons for terminal offline are analyzed in four aspects, that is, the status of the encryption machine 1, the connection status 2 between the front-end server and the collect...

Embodiment 2

[0079] This embodiment provides an offline detection system for power distribution terminals, including:

[0080] The first detection module is used to periodically detect the startup status of the encryption machine, the front-end server and the acquisition server;

[0081] The second detection module is used to periodically detect the encryption, decryption and authentication status of the encryption machine;

[0082] The third detection module is used to periodically detect the heartbeat state between the front-end server and the collection server;

[0083] The fourth detection module is used for periodic detection according to the isolation state between the front-end server and the collection server;

[0084] The analysis module is used to set the detection thread, judge the detection results of the above states in turn, and obtain the offline detection results and offline reasons of the power distribution terminal.

[0085] It should be noted here that the above module...

Embodiment 3

[0087] This embodiment provides an offline detection platform for power distribution terminals, including the offline detection system and display system described in Embodiment 2.

Abstract

The invention discloses a power distribution terminal offline detection method, system and platform. The method comprises: periodically detecting the starting states of an encryption machine, a frontserver and a collection server; periodically detecting encryption, decryption and authentication states of the encryption machine; periodically detecting a heartbeat state between the front server andthe acquisition server; wherein the period detection is based on the isolation state between the front server and the acquisition server; and setting a detection thread, and sequentially judging thedetection results of the states to obtain an offline detection result and an offline reason of the power distribution terminal. The off-line state of the power distribution terminal can be rapidly detected, the off-line reason and the abnormal node causing off-line can be accurately positioned, the terminal off-line defect elimination time is reduced, the capability of monitoring the line operation state in real time by the power distribution automation line is effectively guaranteed, and the power supply reliability is improved.
