摘要(Abstract)：

高压直流线路在我国实际工程中得到广泛应用,基于Deutsch假设的方法和有限元法常用来计算其地面合成电场。为此,对比分析了2种计算方法的区别及可能造成计算误差的原因,讨论了采取不同的方法计算同一水平排列或垂直排列高压直流线路地面合成电场时带来的计算结果差异。结果表明:对于水平排列直流线路,采用基于Deutsch假设的方法得到的地面合成电场最大值与等效导线有限元法的相对差别不到4%,而与分裂导线有限元法的相对差别通常在10%以上;对于垂直排列直流线路,采用基于Deutsch假设的方法得到的地面合成电场最大值与等效导线有限元法的相对差别在5%~15%之间,而与分裂导线有限元法的相对差别通常在30%以上。

关键词(KeyWords)： Deutsch假设;有限元;高压直流输电线路;合成电场;相对差别
