Abstract
As the scale and complexity of power systems continue to expand, the safe and stable operation of electrical equipment has become critical for ensuring the reliability and economic efficiency of the entire power system. Traditional fault diagnosis techniques face numerous limitations when dealing with massive amounts of data, leading to the emergence of big data-based fault diagnosis technologies for electrical equipment. This study aims to enhance the accuracy and timeliness of fault diagnosis by leveraging big data technology. A big data platform integrating multiple data sources is constructed to consolidate multidimensional data including operational status of electrical equipment and environmental factors. Data mining algorithms such as clustering analysis and association rule mining are employed to uncover underlying patterns in the data, establishing a fault feature library and training fault diagnosis models. The results demonstrate that this approach can effectively identify different types of fault patterns and exhibits high sensitivity in early fault warning, reducing false alarm rates by more than 30% compared to traditional methods. Innovatively integrating big data technology with electrical equipment fault diagnosis, this research provides new insights into intelligent fault diagnosis, not only improving diagnostic efficiency but also offering strong support for preventive maintenance of power systems, thereby facilitating the development of power systems towards intelligence.
