Under the influence of environment and interference factors between distribution lines in communication technology,the line fault is easily caused by the communication technology,and the adaptive location of the fault is needed.An adaptive localization algorithm based on the adaptive channel repair and fault spectrum feature extraction is proposed.The link equilibrium control model is constructed.In communication technology,the output channel model of distribution line is used in the communication system to analyze the output spectrum of distribution lines and to separate the characteristics of interference.The blind source location technology is used to locate the fault feature points of the distribution lines under the communication technology,and the spectrum characteristics of the distribution lines are extracted with the correlation matching detection method.The fault diagnosis and adaptive positioning are carried out according to the difference of the spectrum.The simulation results show that the adaptive positioning of the distribution line fault with this method is more accurate and the positioning accuracy is better.
