摘要

电力电子化趋势导致电力系统高频扰动分量快速增加，迫切需要全面分析研究电容式电压互感器（CVT）宽广频率范围的频谱特性，确保电力系统测量、控制保护装置安全可靠运行。基于CVT结构特点，文中采用传递函数的方法分析了影响CVT频谱特性的主要因素及其影响结果，在此基础上提出了宽频域CVT谐波分析模型，基于该模型的频谱特性分析结果与前述CVT影响因素分析结论吻合；最后文中还举例分析了CVT频谱特性研究的实际应用场景。

Abstract

The trend toward power electronicization has led to a rapid increase in high frequency disturbance components in power systems

creating an urgent need to comprehensively analyze and study the spectral characteristics of capacitive voltage transformer(CVT)over a wide frequency range

so as to ensure the safe and reliable operation of power system measurement

control

and protection devices. Based on the structural feature of CVT

in this paper the transfer function method is used to analyze the main factors influencing the CVT spectral characteristic and their corresponding effects and

on this basis

a wide frequency domain harmonics analysis model for the CVT is proposed. The spectral characteristic analysis results based on this model are consistent with the conclusions drawn from the aforementioned analysis of influencing factors. Finally

the practical application scenarios of the CVT spectral characteristic study are also illustrated through examples.
