Analysis on power line harmonic radiation in China space

  • 摘要: 研究了利用DEMETER卫星电磁场探测数据辨识电力线谐波辐射(PLHR,Power Line Harmonic Radiation)事件的方法,探讨了我国空间中PLHR事件的特点.通过采用时频分析和Welch功率谱估计法分析了2005—2010年6年我国空间中的全部卫星电场强度探测数据,共发现151例PLHR事件,给出了PLHR事件的统计分析和典型实例.结果表明我国空间PLHR事件的频率分布在1 000~4 500 Hz之间,多为50 Hz的奇数倍,间隔为50/100 Hz.PLHR事件与我国电网发展和变化有密切关系,与地磁活动水平无关,呈现出昼夜差异和季节差异.最后给出了影响PLHR事件探测的可能因素.
