摘要

本文研究了如何使用智能电表测量低压馈线的线路阻抗，以提供有关保护设置的适当性、基础设施恶化、基础设施损坏等方面的信息。本文针对南非使用的两种接地方案，研究了中性线断裂的后果。使用智能电表测量线路阻抗的可行性是通过一个低压馈线实验模型和位于用户安装处的实验性智能电表进行评估的。实验结果表明，智能电表可用于估算线路阻抗，以检测可能出现的中性线断裂或保护接地和中性线导体故障。

Continuous Line Impedance Assessment of LV Feeders Using Smart Meters

This paper investigates the use of smart meters to measure the line impedance of LV feeders to provide information on the adequacy of protection settings, deteriorating infrastructure, damaged infrastructure, etc. The consequences of a broken neutral conductor are examined for the two earthing schemes used in South Africa. The feasibility of measuring the line impedance using smart meters is evaluated using an experimental model of an LV feeder with experimental smart meters located at customer installations. Experimental results showed that the smart meters can be used to estimate the line impedance to detect a possible broken neutral or protective earth and neutral conductor failure.
