Abstract
To reduce passive interference caused by transmission lines with short-wave frequency direction-finding stations, the impacting factors and law of electromagnetic interferences caused by transmission line on direction-finding station under the energizing of radio wave were researched by means of changing parameters in computation model. Research results showed that during the computation of passive interference the directions of 0°or 90° which brought about the strongest interferences, should be chosen as the direction of incident wave, and to meet the requirement of computational accuracy it was appropriate to choose the number of iron towers as 30. The protection distances for short-wave frequency direction-finding stations were computed in the case of various transmission lines in different voltage classes. Comparing computation results with protection distances specified in China National Standard, it was shown that the protection distances specified in China National Standard were relatively conservative. Based on the research results and according to practical experiences from actual projects, the protective measures, which could be applied to transmission lines and direction-finding stations respectively, were proposed to reduce passive interference caused by transmission lines with short-wave frequency direction-finding stations.关键词
