变压器绕组等效模型参数的频域辨识

Frequency Domain Identification of Equivalent Model Parameters of Transformer Winding

利用变压器绕组的频率响应，在频域中借助最小二乘法中的Ｇａｕｓｓ－Ｎｅｗｔｏｎ辨识方法，可以方便、快速地辨识变压器等效模型的参数。并借助一台模型变压器进行了验证，误差很小。

This paper presents a methodology to identify the equivalent model parameters of transformer expediently and quickly. The identification is performed in the frequency domain from frequency response of transformer winding by using Gauss-Newton method of least squares. By means of a transformer modeling, it verifies that the error is very small.
