摘　　要：根据频域故障电力传输线故障节点导纳方程推导一种基于分布参数的双端故障测距判据。该判据可以对不对称的故障进行故障定位 ,这些故障包括单相接地故障、两相接地故障和两相短路故障。该判据不要求传输线分布参数对称 ,应用不受对端系统阻抗的影响 ,不受传输线故障时的过渡电阻变化的影响。The justifying conditions of fault location are derived using distributed\|parameter nodal admittance equation of fault transmission line based on electrical quantities of two terminals. The justifying conditions can be used to justify the location of faults, including single phase earthing, two phases earthing and two phases shorting. These conditions are not affected by the unsymmetrical distributed\|parameters of transmission line, the remote system impedances and the transit resistance.
