摘　　要：随着全球工业化进程的大力推进,高压输电系统逐渐成为电磁环境监测的主要人为干扰源之一。本文总结了以法国DEMETER卫星电磁场数据为主开展的高压电力线辐射研究的最新成果,对电力线产生的各类空间电磁扰动现象及其时空分布特征进行了归纳分析,其中包括电力线谐振辐射(PLHR)、磁层线辐射(MLR)、ELF/VLF辐射、高能粒子沉降等,并对与其耦合机制相关的电磁波传播及波粒相互作用模型进行了总结讨论,旨在对中国电磁监测试验卫星(CSES-1)数据处理方法、干扰识别和地震弱信号提取分析提供更多的参考信息。With the fast development of global industrialization,high-voltage power lines have become one of the man-made interferences in electromagnetic environment monitoring.In this paper,recent achievements on power line radiations have been summarized,especially by using the satellite electromagnetic observations from DEMETER,such as power line harmonic radiation(PLHR),magnetospheric line radiation(MLR),ELF/VLF emissions,high energetic particle precipitation,etc.And then the coupling models including electromagnetic wave propagation and nonlinear wave-particle interaction have been introduced and discussed.It is aimed to provide more information for the data processing and analyzing techniques in the upcoming China Seismo-Electromagnetic Satellite(CSES-1)mission when the same PLHR signals are dealt with or the weak earthquake-related disturbances are distinguished.
