Abstract
In order to enhance quality and efficiency shortwave monitoring and avoid the influence of electromagnetic interference, active jamming mechanism of high voltage power line affecting shortwave monitoring was analyzed in this paper. According to the calculation principles of vertical dipole model radiation ifeld and corona ifeld of single high voltage power line, 3MHz—30MHz electromagnetic interference was modeled and analyzed. In addition, active interference benchmark level of high voltage power line was quantitatively calculated and compared with tested data. Results show that, in frequency range of 3MHz—30MHz, the strength of electromagnetic interference is different in the conditions of multiple and single high voltage power lines; but the change trend of electromagnetic interference in these two conditions is overall consistent with the change trend of tested data ifeld strength.关键词
