中文摘要:
      高压输变电设备电磁辐射主要体现在工频电磁场辐射、电气噪声和电晕辐射干扰,它可以改变其周围的电磁环境。本文利用输电设备的电磁性能推导了高压输电线路和变电站电磁环境的表达式,引入散射功率比的概念分析了散射干扰。采用高精确度定向天线扫描法测量输变电设备周围环境的反射、散射对通信信号造成的影响。实测数据结果表明,高压输变电设备会造成散射干扰,使得电波传播的多径效应更加明显,从而影响远端接收场强的大小。
英文摘要:
      The electromagnetic radiation of high voltage power transmission equipment mainly includes the constant-frequency electromagnetic radiation,electrical noise and corona radiation interference,which can change the electromagnetic environment around. The analytical expressions of electromagnetic environment are derived for the high-voltage transmission lines and substation. And the scattering interference and shielding effect are analyzed. A test method is designed to measure the impact on wireless communication signals. The test results show that high-voltage power transmission equipment may cause interference scattering, which makes radio propagation multi-path effect more significant,thus affecting the strength of remote reception field.
