摘要针对实际直流输电线路垂直断面地势起伏而传统无线电干扰计算方法只适于断面平坦地势的问题,基于遗传算法和信赖域正则化法分别优化计算直流输电线路电场模拟电荷空间位置和电荷量,提出复杂导线垂直断面地势下直流输电线路无线电干扰分析方法,并将该方法应用于云广特高压直流线路垂直断面的无线电干扰分布计算,通过仿真计算值与测量值的误差分析表明,该方法具有较好的收敛性和计算精度。对直流输电线路设计、改造和环境评估具有工程应用价值。

Abstract：The tradition radio interference(RI) for flat terrain problem should become unreliable when the actual DC transmission lines usually pass through complex vertical section terrains of conductors. Therefore, both the trust region regularization method and genetic algorithm are integrated to analyze complex terrains RI distribution for the improvement of simulation charge locations and the charge quantity, respectively. Furthermore, the convergence and accuracy reliability of the proposed method can be verified by comparing the errors between the RI measurement and simulation values from the section of Yunnan to Guangzhou(YG) project. Consequently the proposed algorithm should benefit engineering applications for transmission line design, renovation and environmental evaluation of complex terrain.

Key words： DC Transmission transmission lines radio interference trust region regularization method electromagnetic environment genetic algorithm
