    摘要:

    为了寻求一种适合交直流同塔架设线路的无线电干扰与可听噪声计算方法，从理论上分析了混合线路表面场强的特点，利用线性叠加原理求出混合线路表面场强，并结合晴天和雨天对交流和直流线路电晕程度的不同影响，提出在同一种天气状况下计算交直流线路无线电干扰与可听噪声。用3种计算无线电干扰与可听噪声的方法，分晴天和雨天情况进行计算比较，结果表明3种方法中BPA修正公式计算值最大，该方法可视为目前计算交直流同塔线路无线电干扰与可听噪声的有效方法。

    Abstract:

    It aims to search for a proper calculation method of radio interference and audible noise to AC/DC hybrid lines arranged on the same tower. First, the characteristics of surface field strength were analyzed theoretically; second, the synthesized field strength was calculated with linear superposition theorem; then the principle, which contains radio interference and audible noise of hybrid lines should be computed in the same weather, was proposed in this paper combined with influence of humidity to corona. The results of three calculation methods were compared and calculated in a sunny and a rainy day. And it indicates the BPA correction formula is an effective method to calculate radio interference and audible noise of AC/DC hybrid lines at present.
