基于智能电能表的新型电力系统低压配电网线阻抗计量
Impedance Measurement of Low-Voltage Distribution Network Cable in New Power System Based on Intelligent Electricity Meter
摘要
Abstract
A smart meter for measuring feeder impedance in LV network is proposed to provide information about the safety of power grid protection devices and the extent of infrastructure damage.In two earthing schemes,the consequences caused by the disconnection of neutral line are checked respectively.The feasibility of using smart meters to measure line impedance is evaluated based on the experi-mental model of LV feeders.The experimental results show that the smart meter can be used to estimate line impedance and thus detect possible neutral line protective earth and neutral line fault.关键词
