| 摘 要： | 中波广播天线周围存在的无源干扰,主要来源于场地内其它频率的发射天线和场地周边高压架空输电系统的影响。本文采用矩量法作为计算的数值方法,建立中波广播发射天线和高压输电线路的仿真模型,通过FEKO软件仿真,分析场地内其它频率发射天线和场地外110kV高压输电线路对江苏广播585kHz中波天线的无源干扰影响,为中波广播发射台合理规划天线场地提供理论依据。

| Abstract: | Passive interferences on MV transmitting antenna are mainly due to transmitting antennas at other frequencies inside the station and overhead high-voltage transmission system around the station.In this paper,moment method is used to establish simulation model of MW transmitting antenna and high-voltage transmission line.By simulation with FEKO software,the influence of passive interferences on 585 kHz antenna is analyzed,and passive interferences come from transmitting antennas at other frequencies and 110kv high-voltage transmission line.The results provide theoretical basis for reasonable planning of transmitting antenna site for MV transmitting station. |
