Abstract :
The active interference of ultra-high-voltage (UHV) AC transmission line (TL) to AM receiving station is measured in the UHV AC base of SGCC in China, the distance for active interference prevention is calculated. Based on the method of moment, the model of the whole TL is built using NEC simulation software. Therefore, the passive interference of UHV AC TL to AM receiving station is also computed. The relationship between passive interference and the protecting distance, the working frequency of the station, and the incident direction are proved respectively. General considering the active interference and passive interference, effective protecting distance between UHV AC TL and the AM receiving station is recommended in the end.
