Abstract
Based on the perspective of data fusion, in response to the low level of automation in fault localization in a certain city's power distribution network and underutilization of data from various systems, a multidimensional information fusion‑based power distribution network fault diagnosis system is developed. It is achieved by integrating system data from the distribution network dispatch management system, SCADA system, fusion terminals, and data acquisition systems via an internal private network. The system can be divided into two parts: the front‑end user interface and the back‑end server. The front‑end user interface is developed using the Visual C++6.0 development environment and modularizes different functional components. The back‑end server is implemented using a database system developed based on Java Web technology. The system is user‑friendly, reliable in operation, highly adaptable, and exhibits good scalability. It enables fault localization, isolation, and reconstruction in power distribution networks. It is convenient for province‑wide promotion and holds practical engineering significance for the development of power distribution automation. The system has been undergoing trial operation in a specific region, and the results have been positive.
