摘要:

提出了一种基于放电图谱物理仿真的局部放电检测仪性能评估方法,并开发了一套评估系统。系统从现场检测、模拟试验和数字仿真三种途径收集典型放电图谱并形成数据库。参考局部放电校准仪结构,基于可编程波形发生模块构建了局部放电脉冲序列物理仿真系统,仿真输出数据库中的典型局部放电图谱,用以评估数字局放仪诸如放电类型模式识别等高级功能。本文对所研发系统的结构和其产生脉冲序列的特征进行了详细阐述,系统在数字式局部放电测量仪器上的应用案例表明了该评估系统的应用前景。

Abstract:

This paper proposes an evaluation method and a system based on the simulation of partial discharge patterns to evaluate the performances of the digital partial discharge measuring instruments. Referring to the structure of partial discharge calibrator, the system can physically simulate and output PD patterns using arbitrary waveform module to evaluate such performances as partial discharge pattern recognition. These partial discharge patterns are obtained from mathematical models or experiments on artificial defects or online measurements and saved in a database. The structure of the system and the characteristic of the generated charge sequences are discussed. The potentiality of the developed characterization system has been proved in the evaluation of the advanced features of some digital PD measuring instruments.

Key words: Characterization system, calibration, partial discharge (PD), digital PD measuring instrument, pattern classification
