Abstract

The transmission line will produce the phenomenon of breeze vibration under the influence of the environment, and the long-term breeze vibration will cause damage to the transmission line, and then cause immeasurable economic losses. Given the problems of the existing transmission line breeze vibration monitoring system, such as single monitoring mode, insufficient monitoring accuracy, complex communication mode, real-time online monitoring, and early warning, a new line breeze vibration monitoring system based on NB-IoT communication module is proposed. The system uses an STM32F103C8T6 embedded microcontroller and micro-electro-mechanical System (MEMS) accelerometer sensor to collect real-time line status data. The data is reported to the OneNET cloud platform through the narrowband IoT private network to achieve online monitoring of line vibration status. After testing, the line vibration monitoring system has the advantages of real-time data reporting, high accuracy of output data, and low power consumption. The system works stably and can monitor the vibration state of transmission lines in real-time and complete early warning and other functions, which can promote the prevention of line vibration and strand breaking and maintain the safe operation of the power system.
