Abstract
With the development of smart grids, distribution transformers, as critical components of power systems, play a vital role in ensuring the safe and stable operation of these systems. Consequently, real-time monitoring of their operational status has become increasingly important. To address this need, constructing an IoT-based condition monitoring system for distribution transformers has emerged as a research hotspot. This study aims to achieve comprehensive, real-time, and precise monitoring of distribution transformer operations through IoT technology. A ZigBee wireless sensor network is employed to form the data acquisition layer, utilizing various sensors to obtain key parameters such as oil temperature, vibration, and partial discharge. NB-IoT communication technology is then used to transmit the collected data to cloud servers, where data storage, processing, and analysis are conducted on the cloud platform. A big data analysis-based condition assessment model is established, which can accurately determine the health status of distribution transformers and predict the probability of fault occurrences. The results indicate that this system effectively enhances the efficiency and accuracy of distribution transformer condition monitoring. It innovatively integrates IoT with distribution transformer condition monitoring, providing new ideas and technical means for intelligent operation and maintenance of power systems. This approach facilitates the timely discovery of potential faults, reduces power outage incidents, and ensures the safe and reliable operation of power systems.
