Abstract

The invention discloses a device and method for power distribution environment monitoring and automatic fault removal, including a data acquisition unit, a field CPU, a main CPU, an operation and maintenance control center, a UPS, and an energy storage and breaking mechanism. Each of the field CPUs converts data The relevant status of the equipment line collected by the acquisition unit is compared with the threshold value set by the fiber grating sensor node and summarized to the main CPU, which is stored by the main CPU and displayed on the display screen. Each power distribution point is represented by a node, and each distribution point is represented by a chain. The road represents the data transmission path, and all status parameters are displayed in the attached table. According to the color of the nodes and links, it is judged whether the power distribution equipment in the power distribution room is faulty. The present invention builds a local area network through the mode of one control and multiple, summarizes the basic data and realizes joint management, and judges the process of the dangerous situation through intelligent analysis of the data, and can take active protection measures in time at special moments or failure stages, which enhances stability and reliability It also has the advantages of high integration and no electromagnetic interference.

Description

technical field

[0001] The invention relates to the technical field of power distribution environment monitoring, in particular to a device and method for power distribution environment monitoring and automatic fault removal. Background technique

[0002] In recent years, with the continuous development of the distribution network cable process, the structure of distribution network lines has become more and more complex, and there are many branch lines. At the same time, the requirements for the stability and reliability of power distribution sites have become higher and higher. Various sensing devices are installed inside, and the sensing data is uploaded to the twin power distribution room or shadow power distribution room through the Internet of Things, 5G and other technologies, and then controlled by the on-duty management personnel.

[0003] After searching, the patent application number 201610783123.6 discloses a method for monitoring the operating environment of pow...

Examples

Embodiment 1

[0046] refer to figure 1 with figure 2 , a device for power distribution environment monitoring and automatic fault removal, including a data acquisition unit, an on-site CPU, a main CPU, an operation and maintenance control center, and a UPS. There are multiple data acquisition units, and the multiple data acquisition units are respectively set in multiple Each power distribution room is used to collect the environmental data in the corresponding power distribution room. Multiple data acquisition units are respectively connected to the on-site CPU for receiving the environmental data collected by the corresponding data acquisition unit through signals. Each on-site CPU is connected through the signal Connected to the main CPU for receiving the corresponding power distribution room environmental data sent by multiple on-site CPUs and giving an alarm according to the abnormal state information in the power distribution room environmental data. The main CPU is connected to the ...

Embodiment 2

[0050] Such as image 3 As shown, this embodiment provides a method for power distribution environment monitoring and fault self-removal. Each on-site CPU compares the relevant state values ​​of the equipment lines collected by the data acquisition unit with the threshold values ​​​​that have been set by the fiber grating sensor nodes. And aggregated to the main CPU, and stored by the main CPU and displayed on the display screen, each power distribution point is represented by a node, the data transmission path is represented by a link, and all status parameters are displayed in an attached table. According to the color of the node and the link, judge Working status of power distribution equipment, including:

[0051] When the nodes and links are both green, it is judged that the power distribution equipment in the power distribution room is in normal working state, and all state parameters are dynamically displayed in a tabular form step by time;

[0052] When at least one o...
