摘要
根据频域故障传输线的分布参数节点导纳方程推导了一种双短故障测距方法。该方法可以对不对称故障进行定位,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;而且不要求传输线分布参数对称,不受系统阻抗的影响,不受过渡阻抗的影响。
This paper derives the justifying conditions for fault location based on distributed parameter nodal admittance equations of faulty transmission line. This justifying conditions based on electric quantities of two terminals, and can be used to justify fault location, including single phase earthing fault, two phase earthing fault and two phase shorting fault. The condition is not affected by unsymmetrical parameter of transmission line, system impedence and transit impedence.
