AI Technical Summary
In complex power distribution networks, traditional traveling wave ranging methods rely on reflected wave identification, which has low reliability, while the two-end method relies on centralized processing at the master station, making it difficult to achieve rapid and accurate fault location without relying on the central master station.
By using multi-terminal traveling wave collaborative calculation and cross-validation, and leveraging the peer-to-peer interaction and collaborative calculation of distribution terminals, the arrival time information of the fault traveling wave front is obtained. Topology consistency, data self-consistency and wave velocity consistency are verified, and the final fault distance is generated and the confidence level is evaluated.
It achieves unique identification and precise location of fault sections in complex power distribution networks, and features a distributed architecture, strong fault tolerance, and high positioning accuracy.
