摘要
本文致力于对电力电缆局部放电(Partial discharge,PD)定位的研究进行了归纳和总结。在电力电缆PD定位方法中,最为经典的方法莫过于使用单传感器的时域反射(Time domain reflectometry,TDR)法。基于时域反射法,许多改进的电力电缆PD定位方法被提出。若从PD传感器的使用数量上考虑,这些研究方法可分为以下两种类型:基于单传感器的PD定位方法和基于多传感器的PD定位方法。针对这些研究方法,本文进行了介绍并做了优缺点分析。在基于使用PD传感器数量考虑的方法研究之上,还有一些学者着力于对PD信号处理的定位研究。同样,对这些研究方法也进行了介绍和优缺点分析。
This paper aims to investigate and summarize the researches on the PD location of power cables.Among these PD location methods for power cables,the most commonly used method is the time domain reflectometry(TDR)method using one sensor.Based on the TDR method,many improved PD location methods for power cables have been proposed.Considering the number of PD sensors used,these methods can be divided into the following two types:PD location methods based on one sensor and PD location methods based on multiple sensors.In the paper,these methods are introduced and their advantages and disadvantages are analyzed.In addition to these methods,there are still some scholars devoting themselves to the location research of PD signal processing.Similarly,they are also introduced and their advantages and disadvantages are analyzed.
