基于输电线路的分布式参数模型，采用两端的电气量进行测距计算，提出了双端测距优化算法。该算法详细分析了故障时线路各点电压与电流的关系，利用接地电阻阻性特征确定故障位置，不受线路负荷、系统阻抗和过渡电阻的影响，且具有较高精度。

Based on the distributed parameter model of transmission line , the optimization algorithm for two-terminal fault lo-cation is presented by adopting the electrical quantities at two terminals for the calculation of fault location .This algorithm makes a detailed analysis on the relationship for each point between its voltage and current when there has a line fault .Mean-while, this method also utilizes the resistive character of resistance to determine the fault location , which is not affected by the influence of line load , system impedance and transition resistance , and finally obtains a relatively high accuracy .
