Reradiation Interference Solution for High-voltage Transmission Lines Based on LE-PO-MoM Method

Reducing the reradiation interference of high-voltage transmission lines to neighboring radio stations is one of the key problems that need to be solved urgently in the construction of overhead high-voltage transmission lines. However, due to the poor accuracy of the current algorithm of Physical Optics in calculating the ultra-large electric size target, according to the structural characteristics of the high-volage transmission tower, conductor and fitting, the Large Element Physical Optics algorithm and Method of Moments are combined to calculate the scattered electric field of the high-volage transmission lines, and then the reradiation interference level is calculated. This algorithm can ensure the computational efficiency to a certain extent, and further improve the solution accuracy.
