摘要/Abstract

摘要： 特高压输电线路工程的建设对于实现远距离电力系统互联十分关键，随着特高压输电线路工程的建设，其对线路临近的甚高频信号（30~300 MHz）的无源干扰问题亟待解决。针对矩量法计算量的局限性以及现有特高压输电线路甚高频无源干扰问题尚没有确定的求解方法的问题，建立了特高压输电线路无源干扰的面模型，提出了采用迭代物理光学法（iterative physical optics，IPO）对甚高频特高压无源干扰问题进行求解的思路。以甚高频频段（30~300 MHz）为例，根据IPO理论，对特高压输电线路模型中存在的不连续情况进行了修正，对该频段下的无源干扰问题进行了求解。研究表明，采用IPO方法可以实现对甚高频特高压输电线路无源干扰问题的求解，也为该问题的确定求解方法提供了可行的思路。

Abstract: The construction of UHV transmission line project is crucial for realization of long-distance power system interconnection. Study of VHF signals(30~300 MHz) passive interference adjacent to UHV transmission line is also very important. A passive jamming surface model of high voltage transmission line is proposed to use IPO(Iterative Physical Optics) method to solve VHF/UHV passive jamming problem. In VHF frequency band(30~300 MHz), discontinuities exist in UHV transmission line model are compensated by IPO method in order to solve passive jamming problem. The results show feasibility of proposed method.

Key words: UHV transmission line, ultra high frequency (VHF), IPO, reradiation interference
