摘　　要：在导体的数量,介质的层数以及导体的横截面形状均是任意的条件下,论文提出利用矩量法计算高压输电线附近电场强度,其基本理论和相应的计算机程序可用于对高压线附近的电磁污染的评估,同时还可用于分析电力线对通信线路的干扰。在计算实例中,计算结果和相应的解析法有很好的一致性,证明了本方法的正确性和有效性。Under the conditions of the number of conductors and the shape of cross-section of lines assumed to be arbitrary,a moment method analysis is presented in this paper for computing the electrical field intensity in the surrounding space of a high-voltage multiconductor transmission line above the ground. As a result, this formulation and its corresponding computer program would be applicable to the assessment of electromagnetic transmission line system and may be used in calculation of interference between power system and telecommunication lines as well. The computed results are compared with those obtained by using an analytical approach and a good agreement between the two results justifies the correctness and effectiveness of this method.
