| 摘 要： | 提出了一种基于阻抗测量法和解二次方程法相结合的改进单端测距算法.该算法不但具有很强的鲁棒性,又从原理上消除过渡电阻的影响因而具有较高的精确性.该算法只需要线路一端的电气量,简单灵活;而且基于工频量,对采样率要求不高,具有较高的工程实用价值.最后用Visual C++编程实现该算法并通过实际的工程应用证明了其有效性.

| Abstract: | The paper brings forward a plan of improved single-terminal location algorithm based on solving a second order equation and measured resistance algorithm.This algorithm is quite robust and has a high accuracy by eliminating the affection of transition resistor.And it is simple and flexible because only one end of electrical signal of the line is needed.Besides,it is based on the power-frequency voltages and currents.Therefore,it does not need high sampling rate and can be easily implemented in protection de... |
