【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.更多还原
