摘要:

IEEE对中波频段输电线路无源干扰谐振机理及其影响因子进行了较为深入的研究,但相关结论无法解释短波频段无源干扰仍存在的谐振现象。为得到短波频段输电线路无源干扰谐振的决定性影响因子,考虑各种可能对干扰造成影响的因素,如线路档距、铁塔数量、导线、地线等单一宏观结构,研究输电线路与天线组成的电磁开放系统中场域的无源干扰水平。引入灰色系统理论及相关性分析,计算各种影响因子对干扰变化的灵敏度,得到各种宏观结构与干扰的关联程度。分析结果表明,线路档距是短波频段无源干扰谐振的决定性影响因子,线路设计阶段可采取调整档距的方法规避干扰极值频点。

Abstract:

IEEE gives deeper research on the resonance mechanism and impact factors of passive interference resonance (PIR) for transmission lines at medium-wave frequency. However, the resonance phenomenon existing at short-wave frequency (SF) can’t be explained by above research conclusions. In order to research the decisive impact factors of PIR for transmission lines at SF, the possible impact factors of interference resonance, such as tower spans, tower number, conductor, grounding wire and other single macro structure were considered, and the passive interference level in the electromagnetic open system composed of transmission line and antenna was studied. Grey system theory and correlation analysis were introduced to calculate the sensitivity of impact factors to interference change, and the correlation degree of various macro structure and interference was obtained. The results show that the decisive impact factor of PIR at SF is tower spans, which can be adjusted to evade the resonance frequencies at line design stage.

Key words: transmission line, passive interference resonance, grey system theory, correlation analysis, impact factor
