直流线路合成场强现有计算方法及无网格法的应用

Application of total electric field strength of DC transmission line under existing method and meshless method

针对直流线路合成场强现有计算方法展开分析，阐述现有计算方法的优缺点，提出利用无网格法计算直流输电线路合成场强和离子流。在此无网格法计算原理的基础上，对贵广直流线路单级运行时的合成场强进行计算。证明贵广直流线路在单级运行时的合成场强及离子流密度均符合我国制定的相应标准。

Abstract： This thesis explains the advantages and disadvantages of the existing calculation method by analyzing the existing total electric field strength calculation method, and proposes the meshless method to calculate total electric field strength and ion flow of DC transmission line. The total electric field strength is calculated based on the principle of meshless method, and it is proved the total electric field strength and ion flow density are in line with the corresponding standards in China during single - level operation of Guizhou - Guangdong DC transmission line.
