为了有效研究750 kV/330 kV混压同塔四回输电线路电磁环境,文中采用模拟电荷法计算同塔四回混压输电线路导线下的工频电场,采用毕奥-萨瓦定律计算磁场数值,并采用激发函数法进行了无线电干扰的计算,同时运用BPA公式进行了可听噪声的计算。针对同塔四回混压输电线路不同导线相序布置、不同分裂间距、不同杆塔呼称高进行了系统的研究。结果表明:A、B型塔采用A_6和B_6相序布置可以有效改善线路下方电磁环境;导线分裂间距对电场、磁感应强度影响较小;电场、磁感应强度、无线电干扰和可听噪声随着杆塔呼称高增加而降低,其中电场、磁感应强度和无线电干扰减幅较大,可听噪声减幅较小。依据相应的电磁环...

In order to effectively analyze electromagnetic environment of the 750 kV/330 kV quadruple-circuit transmission line on the same tower,method used to electric field calculation is simulation charge method,and method used to magnetic field calculation is Biot-SaUart Principle in this paper. And method used to radio interference and audible noise calculation is excitation function method or BPA formula. The influence regularities with different the phase sequence arrangement, the bundle spacing and tower’s height are analyzed. The results show t...
