摘　　要：在研究激发函数模型的基础上,从电晕电流计算、相模转换矩阵确定等方面阐述了基于激发函数计算无线电干扰的原理及关键环节,并与750 kV 6分裂导线的实测数据进行比对,分析了该算法在计算此类导线无线电干扰时的适用性,解决了采用传统算法计算此类导线无线电干扰结果严重失真的问题,提高了计算多分裂导线无线电干扰的可靠性与准确性,为超/特高压输电线路建设中的无线电干扰影响评估提供了有效的技术手段。The principle and key link of RI calculation based on excitation function are expounded from the aspects of corona current and phase-modal transformation matrix.The calculation results are compared with measured values of 750 kV six-bundle conductor, and the applicability of this method for solving RI of the conductor is analyzed.Considering distortion of the result with traditional RI calculation method,this one based on excitation function is of higher reliability and accuracy in calculating RI of multi-bundle conductor,and is an effective way for RI impact assessment of EHV and UHV transmission lines.
