自适应采样算法在输电线路无源干扰拟合计算中的应用

The Application of Self-Adaptive Sampling Algorithm in Fitting Passive Interference in Transmission Line

利用MBPE技术可以快速预测输电线路散射场的频率响应近似值。但是,输电线路电磁散射计算中通常使用的是等间隔采样。这导致采样数据可能会丢失重要采样点信息,使拟合结果难以控制;或者采样到重复信息,增加计算量。为了达到更准确求解的目的,引入自适应采样算法。在保留快速求解输电线路散射场频率响应的同时,大大提高了计算的准确性。最后运用自适应采样算法求解实际问题,并将自适应采样计算结果与传统等间隔采样计算结果进行比较,证明该方法的准确性。

Using MBPE technology can quickly predict the frequency response of transmission line scattering field approximation.However,the transmission line electromagnetic scattering calculation is usually used in the interval sampling.This results in the possibility that the sampled data may lose important sample points,making the fitting results difficult to control,or sampling to duplicate information to increase the amount of computation.In order to achieve the purpose of more accurate solution,the self-adaptive sampling algorithm is introduced.In the fast solution to the transmission line frequency field response at the same time,greatly improving the accuracy of the calculation is obtained.Finally,the self-adaptive sampling algorithm is used to solve the practical problem,and the results of the self-adaptive sampling are compared with those of the traditional interval sampling.The accuracy of the method is proved.
