Single-ended Fault Location for UHVDC Transmission Line Based on Propagation Time Gap Between Zero and Aerial Mode
摘要
Abstract
There is a nonlinear relationship between fault distance and the propagation time gap between zero mode and aerial mode,and back propagation(BP)neural network with the ability of nonlinear curve-fitting is selected to fit this re-lationship to realize fault location . The propagation time gap in different frequency bands of wavelet decomposition as inputs and the fault distance as outputs are used to train the neural network,and thus a faul location model using neural network is established. Simulation results indicate that the proposed single-ended fault location method useing neural network for ultra high voltage direct current(UHVDC)transmission line based on propagation time gap has higher accu-racies.关键词
