Description

Technical Field

[0001] This invention relates to the technical field of distribution network fault management, specifically to a method and system for distribution network fault location and resource scheduling based on digital twins. Background Technology

[0002] The goal of distribution network fault diagnosis technology is to achieve rapid and accurate fault identification and location. Its core lies in building a multi-layered technical system: First, relying on intelligent terminals and relay protection devices deployed on the lines, instantaneous fault perception and initial section isolation are achieved. This forms the "perception" foundation for diagnosis. Then, algorithms such as traveling wave ranging and impedance analysis are used to compress the fault range from "sections" to "points," achieving meter-level precise location. This is crucial for accurate diagnosis. The current trend is the integration of data-driven and intelligent technologies. By integrating multi-source data such as SCADA and fault waveform recordings, and introducing artificial intelligence and big data technologies, the system can perform more complex fault type identification, cause analysis, and potential hazard prediction. Ultimately, these diagnostic results are linked with the dispatching and operation and maintenance systems to form a complete closed loop from "perception-location-handling-optimization," significantly improving power supply reliability and operation and maintenance efficiency. Existing distribution network hardware fault monitoring cannot achieve intelligent location and handling of hardware faults, nor can it provide visual feedback on distribution network hardware fault handling information based on digital twins.

[0003] Chinese invention patent application CN113674106A, published on November 19, 2021, discloses a combined method for locating grounding faults in medium- and low-voltage distribution networks. The method involves obtaining an original sample dataset and training it using random forest, isolated forest, and clustering algorithms to construct measurement point classification random forest, isolated forest, and clustering models, respectively. The errors of each model are obtained, and corresponding weights are calculated based on these errors. The classification results from these three models are then weighted and fused to obtain a combined classification result. An adjacency matrix algorithm is implemented based on the distribution network topology and fault measurement points to obtain the fault segment location result. A difference metric is determined and used to verify and correct the fault segment location result. Combining multiple models to locate grounding faults in the distribution network and verifying and correcting the location results ensures the accuracy of fault location. However, this technical solution cannot achieve visualized fault diagnosis and maintenance of the distribution network line hardware. Summary of the Invention
