Power transmission line distributed fault diagnosis system suitable for power Internet of things

Abstract

The invention discloses a power transmission line distributed fault diagnosis system suitable for the power Internet of things. The system comprises a monitoring terminal, an edge agent module and a central station system, wherein the monitoring terminal is used for acquiring power transmission line data, and the data comprises traveling wave current, power frequency electric quantity and wire temperature in a wire; the edge agent module is used for encrypting the received power transmission line data and outputting the encrypted data; the central station system is used for receiving the encrypted data and performing calculation processing to realize fault early warning and diagnosis; and the monitoring terminal performs data interaction with the edge agent module through short-distance wireless communication, and the edge agent module performs data interaction with the central station system through a power private network. The system can reduce energy consumption, improve safety, reduce equipment volume, widen the application range and reduce the operation cost.

Description

technical field [0001] The invention belongs to the technical field of electric power system transmission, and in particular relates to a distributed fault diagnosis system for transmission lines suitable for the Internet of Things. Background technique [0002] The Ubiquitous Power Internet of Things is a strategic deployment made by the State Grid Corporation of China in the "Two Sessions" in 2019 to comprehensively promote the construction of "three types and two networks" and accelerate the creation of a world-class energy Internet enterprise with global competitiveness. Practice is an important measure to implement the deployment of the central government and give full play to the leading role of central enterprises, and it is an inevitable requirement to adapt to internal and external situations and challenges. [0003] Around each link of the power system, fully apply modern information technology such as mobile Internet and artificial intelligence, and advanced commu...

AI Technical Summary

Problems solved by technology

Since the monitoring terminal uses the public network to communicate with the central station, there are defects such as high security risks, high network communication costs, single mode, and high energy consumption

These defects have led to the inability of the fault diagnosis system in the existing technology to be incorporated into the new power Internet of Things construction system, which has seriously affected the promotion and development of the power Internet of Things construction in the field of transmission line fault diagnosis.
