AI Technical Summary
Existing fault location technologies lack accuracy and real-time performance in complex power grid environments, and have excessively high requirements for time synchronization and data quality, making it difficult to achieve efficient fault location in high-noise and asynchronous data environments.
Discrete wavelet transform is used to extract high-frequency transient components, combined with cubic spline interpolation to calibrate timestamps, and fused with traveling wave analysis and fully connected neural networks. Through wavelet packet decomposition and least squares optimization methods, a comprehensive fault location report is generated and scheduling instructions are generated.
It significantly improves the accuracy and robustness of fault location, enabling rapid response and high-precision fault location in high-noise, multi-branch power grid environments, meeting the reliability and efficiency requirements of modern smart grids.
