In this research, we aim to construct a completely new partial discharge (PD) monitoring system that applies inexpensive power line communication (PLC). We have proposed a PD detection method and monitoring system (PDMS-PLC) on the basis of PLC signal transfer rare is affected by an error due to disturbance. An attempt is made to identify PD source from the quadrant dependence of information transmission rate (hereinafter referred to PHY rate [Mbps]) by selecting a pair of quadrants of applied voltage phase; i.e. 1st and 3rd quadrants, or 2nd and 4th ones. It was found that the PHY (Abbreviation for the lowest physical layer in the OSI (open systems interconnection) hierarchical model.) rate number distribution reflects the PD characteristics obtained by the phase resolved PD (PRPD) pattern. Environmental noise level is also measured at an actual substation using PDMS-PLC. Consequently, the applicability of PDMS-PLC to PD signal detection and defect type identification is suggested.

新型电力线通信在线局部放电监测系统的构建与实验验证

在这项研究中，我们的目标是构建一个全新的局部放电 (PD) 监控系统，该系统应用廉价的电力线通信 (PLC)。我们提出了一种基于 PLC 信号传输的 PD 检测方法和监控系统 (PDMS-PLC)，很少受干扰引起的错误影响。试图通过选择一对施加电压相位的象限，从信息传输速率（以下简称PHY速率[Mbps]）的象限相关性来识别PD源；即第一和第三象限，或第二和第四象限。发现PHY（OSI（开放系统互连）分层模型中最低物理层的缩写。）速率数分布反映了通过相位解析PD（PRPD）模式获得的PD特性。环境噪声水平也在实际变电站使用 PDMS-PLC 进行测量。因此，提出了 PDMS-PLC 在 PD 信号检测和缺陷类型识别中的适用性。
