Abstract
This study proposes a big data-based fault diagnosis and early warning system for power systems, aiming to address the current demands of fault diagnosis and early warning in this field. Given the increasing complexity of power systems and the expanding scale of data, traditional fault diagnosis methods have become inadequate. Therefore, this research seeks to enhance the accuracy of fault diagnosis and the timeliness of early warnings through the application of big data technology. Methodologically, we integrate various techniques such as data mining, machine learning, and deep learning to construct a comprehensive model for fault diagnosis and early warning. By performing feature extraction and pattern recognition on massive historical data, the model is capable of automatically learning and identifying abnormal behaviors and fault patterns within the power system. Experimental results demonstrate that the proposed model achieves a 20% improvement in fault diagnosis accuracy compared to traditional methods. Additionally, it significantly enhances early warning timeliness, enabling the prediction of potential faults several hours ahead. The innovation of this study lies in the combination of big data technology with power system fault diagnosis, facilitating rapid and accurate fault identification and early warning, thereby providing strong support for the stable operation of power systems.
