摘要
根据电磁场理论和电力系统元件的各序阻抗及架空线路间零序互感的有关理论，分析了多互感线路零序阻抗的特点及零序补偿系数Ｋ值沿线的分布情况，提出了计算多互感线路零序补偿系数Ｋ值的方法，并提出零序补偿系数Ｋ值确定后，如何正确确定“接地距离保护”的Ⅰ、Ⅱ。
In this paper, feature of zero sequence impedance in multi mutual inductance lines and the distribution condition of zero sequence compensation factor K along the lines are analyzed, and the method of calculating zero sequence compensation factor K in multi mutual lines is proposed. With the given K value, determination of the setting values of the first, second and third zone ground distance protection is introduced.
