| description | In view of problems that network topology of underground low-voltage power line is complex and multi-path transmission model is difficult to suit channel modeling of underground low-voltage power line, the paper made a test for channel transmission characteristics of underground low-voltage power line. It indicated that attenuation of underground signal increases with increasing of transmission distance and changes with changing of frequency, and has certain selective fading. It took selective fading as resonant frequency point and used model of series resonant circuit to make modeling simulation for channel attenuation characteristics of underground low-voltage power line, and the simulation result shows that the model of series resonant circuit can well reflect channel transmission characteristics of underground low-voltage power line. |
