Abstract

In transformer production, some manufacturers use aluminum to impersonate copper to reduce the manufacturing cost, which is difficult to be detected and can cause significant losses to the power grid. To address the problem of non-destructive identification of winding material in distribution transformers, we propose a multi- information recognition method by fusing the harmonic resistance coefficient and the appearance parameters of the transformer, namely volume and height. Then the winding material is identified by a trained support vector machine model. The test results demonstrate that our proposed method achieves 90% recognition accuracy for copper transformers and 100% accuracy for aluminum transformers with the test samples. Additionally, the proposed non-destructive method is easier to implement than other methods in engineering.
基于多信息融合的配电变压器绕组材料识别
在变压器生产过程中,有些厂家为了降低制造成本,用铝冒充铜,这种做法很难被发现,会给电网造成巨大损失。针对配电变压器绕组材料的非破坏性识别问题,我们提出了一种多信息识别方法,将谐波电阻系数和变压器的外观参数(即体积和高度)融合在一起。然后通过训练有素的支持向量机模型来识别绕组材料。测试结果表明,通过测试样本,我们提出的方法对铜变压器的识别准确率达到 90%,对铝变压器的识别准确率达到 100%。此外,与工程领域的其他方法相比,所提出的非破坏性方法更易于实施。
