摘要
提出了一种基于矩量法对高压输电杆塔周围空间电场情况进行快速建模分析的方法。以110kV杆式塔型杆塔-线路作为研究对象,应用有限元法与矩量法进行对比分析,确定使用矩量法进行快速建模分析的可行性,并对矩量法建立的输电杆塔模型进行简化处理,对比了杆塔模型简化前后的空间电场特性,确定了简化模型的准确性。
This paper presents a fast modeling and analysis method of space electric field around a high-voltage transmission tower based on moment method.Taking the 110 kV drum tower-line as the research object,the finite element method and the moment method are used for comparative analysis to determine the feasibility of using the moment method for rapid modeling analysis.In addition,the simplified transmission tower model established by the moment method is processed,and the space electric field characteristics before and after the simplification of tower model are compared to determine the accuracy of the simplified model.
