摘要
采用有限单元法分析计算了电力变压器的零序磁场、零序阻抗 ,得出两种典型电力变压器零序阻抗在各种情况下的数值 ,并与实验结果进行比较 ,数值计算值与实测值基本吻合 ,证明采用有限单元法计算电力变压器的零序阻抗是有效的。
The finite element method is used to analyze and calculate zero sequence magnetic field and impedance of power transformers.The zero sequence impedance of two typical power transformers are computed under several kinds of conditions.The results between the calculated impedance and the measuring impedance are well matched.it demonstrates that the method for calculating the zero sequence impedance of transformer is effective.
