基于人工智能的低压安全隐患预警方法研究

Research on Low Voltage Safety Hazard Warning Method Based on Artificial Intelligence

  • 摘要: 故障电弧作为引发低压用电事故的常见安全隐患,存在随机性、隐蔽性及危险性等特点。现有保护方法通常于故障发生后采取相应措施,缺少对故障发生前的预警。本文设计一种基于人工智能算法的故障电弧隐患预警模型,通过提取每个样本中与故障电弧相关性较强的特征值作为故障判别指标对模型进行学习,实现故障电弧的提前精准预测,提高低压用户用电安全系数。实验验证结果表明,该模型准确率高,能够对未来一个周期是否会发生电弧故障作出准确预测,且与DT(决策树)、GRU、RNN等主流分类预测模型对比分析体现出了该模型的优越性。

     

    Abstract: Fault arc, as a common safety hazard that causes low-voltage electrical accidents, has characteristics such as randomness, concealment, and danger. The existing protection methods usually take corresponding measures after a fault occurs, lacking early warning before the fault occurs.This paper designs a fault arc hidden danger early warning model based on artificial intelligence algorithm, and learns the model by extracting the eigenvalues in each sample that have strong correlation with the fault arc as the fault discrimination index, so as to realize the accurate prediction of fault arc in advance and improve the Factor of safety of low-voltage users.The experimental verification results show that the model has high accuracy and can accurately predict whether Arc fault will occur in the future cycle. The comparative analysis with DT (decision tree), GRU, RNN and other mainstream classification prediction models shows the advantages of the model。
