| 摘 要： | 时域有限差分法是一种十分有效的电磁场数值计算方法,本文借助时域有限差分法对GIS同轴波导结构内部发生局部放电时所激发的电磁波的传播特性进行仿真,分析了影响电磁波传播的因素,利用超高频局部放电检测方法对GIS实验段局部放电进行实测,仿真结果和实验结果基本一致,为超高频局部放电检测结果提供了理论支持,进一步论证了超高频局部放电检测方法的正确性和可行性,可以应用于现场实际测量.

| Abstract: | Finite-difference time-domain (FDTD) method is an efficient method for calculation of electromagnetic field. This paper uses FDTD method to simulate the electromagnetic wave propagation of partial discharge excited in gas insulated switchgear (GIS), analyzes the influence factors, and measures the partial discharge in GIS bus bar in laboratory. The results of simulation and experiment are in agreement. These results demonstrate that using ultra-high frequency (UHF) is efficient and feasible, and this method can be used for partial discharge detection on-site. |
