| 摘 要： | 为研究特高压交流输电线路对调幅广播收音台的防护间距,通过特高压交流试验基地的实测数据,得到了特高压交流输电线路的无线电干扰水平,为有源干扰的计算提供了强有力的数据支持。利用NEC电磁计算软件,建立了特高压输电线路的实体模型,计算了无源干扰随频率、入射角度以及防护间距的变化规律,得到了特高压交流线路3种典型塔型的无源干扰水平。最后通过比较有源干扰和无源干扰影响,给出了特高压交流架空输电线路对调幅广播收音台的防护间距计算值。 |
| 关 键 词： | 特高压 交流线路 调幅广播收音台 有源干扰 无源干扰 防护间距 |

| Abstract: | The interference of Ultra-high-voltage(UHV) AC transmission line(TL) to AM receiving station can be classified to active interference and passive interference.The radio interference level of UHV AC TL is got by plenty of measurements in the UHV AC base of SGCC,which can support the calculation of protecting distance caused by active interference.Based on the method of moment,the model of the whole TL is built by using the 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,then the three kinds of typical UHV AC tower's passive interference were got.Generally considering the active interference and passive interference,effective protection distance between UHV AC TL and the AM receiving station is given by calculation in the end. |
| Keywords: | UHV AC transmission line AM receiving stations active interference passive interference protected distance |
