| 摘 要： | 基于输电线路无源干扰面模型,提出了采用大面元物理光学法(Large Element-Physical Optics,LE-PO)对特高频无源干扰水平进行求解的思想.根据LE-PO法的假设,对电场积分方程进行了简化.当激励源为平面波时,采用LP-RWG(Linearly Phased-Rao Wilton Glisson)基函数对铁塔表面感应电流进行离散,推导了输电线路铁塔散射场求解的表达式.采用相关文献算例分析了LE-PO法求解输电线路无源干扰时的计算精度和计算资源.研究表明,LE-PO法的求解精度与PO法一致,但能节省大量的计算资源.

| Abstract: | Based on the surface model of RRI,the calculation idea using large element-physical optics(LEPO)is proposed to calculate the level of RRI.According to the assumption of LE-PO,the electric field integral equation is simplified.When the excitation source is plane wave,LP-RWG(Linearly Phased-Rao Wilton Glisson)basis functions are used to disperse the surface-induced current and the expression of scattering field from the tower of power lines was deduced.Related analysis example is used to analyze the calculation precision and the computing resource of LE-PO.As a result,the computing resources of LE-PO is much less than PO while the calculation precision of LE-PO is the same as PO. |
