摘要

本文提出了一种灵敏度分析方法，以评估计算电力电缆地回阻抗的不同方法在电磁瞬态响应中的影响。灵敏度是根据得到的电压和电流瞬态响应的精度来观察的，这些响应随电缆距离、间距和接地电阻率的变化而变化。在同一准则下，分析了开路电压的传播方式和线路的特性阻抗。

Sensitivity analysis of ground impedances of power cables in electromagnetic transient responses

This document presents a sensitivity analysis to evaluate the impact of different methods used to calculate ground-return impedances of power cables in electromagnetic transient responses. The sensitivity is observed in terms of the obtained accuracy in the voltage and current transient responses varying cable distance separation and ground resistivity. The propagation modes of open circuit voltages and the characteristics impedance of the line are also analyzed under the same criterion.
