Abstract

High-Impedance Arcing Faults (HIAFs) in electrical microgrids are among the abnormal conditions that are difficult to detect by conventional protective devices due to low current and non-linear behavior. In addition, the behavioral similarity of HIAFs to other transient events (TEs) in microgrids leads to classification challenges. This study addresses this issue by proposing a new protective algorithm for the fast and accurate detection of HIAFs and their differentiation from other TEs. The proposed method uses the third harmonic angle of the residual current (THARC) as a key identification feature, which is extracted using a fast, accurate two-layer Master-Slave ADALINE (MS-ADALINE) architecture. The THARC is then smoothed using the Moving Average (MWA) technique, and a new index is introduced for fault detection. Simulations conducted in the EMTP-RV software environment demonstrate that the proposed algorithm can distinguish HIAFs from other TEs under noisy and complex conditions with an accuracy of 99.17% and a detection time of 20 msec. Low computational cost and simple, practical implementation are additional significant advantages of the proposed method.

基于主从ADALINE算法的可再生能源微电网高阻抗电弧故障高速准确检测

微电网中的高阻抗电弧故障（HIAFs）由于其低电流和非线性特性，是传统保护装置难以检测到的异常情况之一。此外，hiaf与微电网中其他暂态事件（te）的行为相似性也给分类带来了挑战。本研究通过提出一种新的保护算法来解决这一问题，该算法可以快速准确地检测hiaf并将其与其他te区分开来。该方法以剩余电流的三次谐波角（THARC）作为关键识别特征，采用快速、准确的二层主从ADALINE （MS-ADALINE）架构提取剩余电流的三次谐波角。然后利用移动平均（MWA）技术对THARC进行平滑处理，并引入一种新的故障检测指标。在EMTP-RV软件环境中进行的仿真结果表明，该算法能够在噪声和复杂条件下区分hiaf和其他te，准确率为99.17%，检测时间为20 msec。该方法具有计算成本低、实现简单、实用等优点。
