Protecting Distance between AM Receiving Station and UHV AC TL
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 WHVRI in China, the distances
for active interference prevention are calculated.According to the actual situation,based
on the method of moment, the model of the whole transmission line is built in the NEC
simulation software; therefore the passive interference from UHV AC transmission line
to AM receiving station is computed.The relationship between passive interference and
the protecting distance, the working frequency of the station,and the incident direction
are proved respectfully.Finally, considering both the active interference and passive
interference,effective protecting distance between UHV AC transmission line and the AM
receiving station is recommended.
