摘要
传统的隔离开关分闸故障诊断方法直接构建了诊断模型,但未对分闸电流特征值进行提取,导致诊断效果不佳.因此,本文提出了一种组合电器中隔离开关分闸故障诊断方法.首先,通过提取分闸电流特征值,降低后续构建模型的复杂度;然后,构建隔离开关分闸故障诊断模型,并设计相应的故障诊断流程图,利用模型实现组合电器中隔离开关分闸故障诊断.实验结果表明,该研究方法对隔离开关分闸故障诊断效果更好,更适合实际应用.
Abstract
The traditional disconnector opening fault diagnosis method directly constructs the diagnosis model,but does not extract the characteristic value of the opening current,causing poor diagnostic effect.Therefore,this paper proposes a diagnosis method for disconnector opening fault in composite apparatus.Firstly,the characteristic value of the opening current is extracted to reduce the complexity of the subsequent model construction.Then,a diagnosis model of disconnector opening fault is constructed,and the corresponding fault diagnosis flow chart is designed.The model is used to realize the diagnosis of disconnector opening fault in composite apparatus.The experimental results show that,the proposed method has a better effect on the diagnosis of disconnector opening fault and is more suitable for practical application.
