摘要

提出了一种基于网络函数的VFTO下变压器绕组响应计算的有效方法。该方法首先用由网络分析仪测量得到的散射参数计算所需的电压传输函数

然后通过矢量匹配法对电压传输函数进行有理函数的拟合

最后

利用与拟合的电压传输函数对应的指数形式的激励响应和输入信号进行时域递归卷积

以获得电压响应。与实测电压响应比较的结果表明:利用传输函数仿真计算得到的结果与测量结果吻合。这说明该方法简单、准确。

Abstract

An efficient method is presented for calculating the response of transformer windings under VFTO based on network function in this paper. Firstly

the voltage transfer functions are calculated from the scattering parameters of each section which is measured by network analyzer. Secondly

the voltage transfer functions are fitted with rational functions by vector fitting codes. Finally

the voltage responses of each section are calculated via recursive convolution using the pulse response and the input signal. They are compared with the measured voltage responses in time domain. The calculated voltages are in agreement with the measured voltages. It shows that the method is simple and correct.
