High-impedance arc faults (HIAFs) occur frequently in distribution networks. An electric arc can easily cause serious accidents. The detection and prevention of arc faults are crucial for the safety of electrical systems and equipment. The electrical characteristics of an electric arc are influenced by various factors such as the environmental pressure, current magnitude, and arc length. Describing these characteristics using conventional mathematical models can be challenging. Hence, in this work, a novel mathematical–physical arc model was established based on the arc discharge mechanism. Compared with the conventional mathematical model, the proposed arc model is more accurate and can reflect the variations in the attribute parameters during the arc discharge process. The proposed model has excellent universality and is applicable under various discharge conditions including varying air pressure, ground resistance, and arc gap length. The model can be used in the detection of HIAFs under different discharge conditions.

一种新型数理电弧模型及其在配电网高阻抗电弧故障模拟中的应用



高阻抗电弧故障(HIAF)在配电网络中频繁发生。电弧很容易造成严重事故。电弧故障的检测和预防对于电气系统和设备的安全至关重要。电弧的电气特性受环境压力、电流大小、电弧长度等多种因素的影响。使用传统的数学模型描述这些特征可能具有挑战性。因此,在这项工作中,基于电弧放电机制建立了一种新颖的数学物理电弧模型。与传统的数学模型相比,所提出的电弧模型更加准确,能够反映电弧放电过程中属性参数的变化。所提出的模型具有良好的通用性,适用于各种放电条件,包括变化的气压、接地电阻和弧隙长度。该模型可用于不同放电条件下HIAF的检测。
