Traveling Wave Fault Location for AT Double-Lines Traction Network of Electric Railways Based on HHT
AT power supply in traction network of electric railways has various advantages, such as high-speed, heavy haul, and plays more and more important role in electric railways system. The paper takes ATP-EMTP as platform to build the model of AT double-lines traction electric network, using single-ended signal for fault location, and analyzes fault signal by Hilbert - Huang Transform. This model has considerable accuracy, which do not change the disposition of existing wiring in railway lines or add any extra equipment, avoiding the deficiency in wavelet transformation and the disturbance by harmonic.
