A Hybrid Transmission Network Traveling Wave Location Method Based on Fault Deduction and Wave Speed Optimization
Addressing the challenges brought by complex hybrid ring networks in fault section location and accurate location, this paper proposes a hybrid transmission network traveling wave (TW) location method based on fault deduction and wave speed optimization. First, the paper analyzes the TW propagation process and establishes equivalent models for each stage of the propagation process, deriving initial TW relationships between measurement points. Based on this, the fault deduction algorithm determines the TW propagation paths, enabling network decomposition of complex hybrid ring lines. Combining the concept of virtual fault (VF), a fault section location model is established, and the fault section is determined by maximizing the similarity of VF waveforms. Utilizing the TW arrival time in non-fault areas after network decomposition, a TW speed optimization model is established to obtain the optimal TW speed solution for the region, achieving accurate location. Verified by the PSCAD simulation platform, this method can accurately locate the fault section and determine the optimal TW speed in complex hybrid ring network scenarios, achieving accurate fault location.
