摘要
局部放电现象在设备绝缘中长期存在会导致绝缘劣化,影响电气设备运行,严重时会引起设备故障,引发停电事故。本课题采用软件实现局部放电信号包络检波研究。具体研究局部放电信号包络检波的算法,并用matlab软件仿真实现。采用希尔伯特算法,通过仿真观察分析该算法的包络检波能力。
Long-term existence of partial discharge in equipment insulation will lead to the insulation degradation, affect electric equipment operation, and more seriously cause equipment failure and blackout. This paper adopts the software for the realization of partial discharge signal envelope detection, specifically the algorithm and simulation with matlab software. The envelope detection ability of the algorithm is simulated and analyzed using the Hilbert algorithm.
