摘要

控制特性和谐波特性是变压器式可控电抗器（controllable reactor of transformer type

CRT）的2个重要特性。文中首先给出CRT绕组电流计算模型;其次

对顺次单支路工作模式和解耦工作模式这2种典型工作模式的特点进行了分析;最后

结合具体算例

基于绕组电流计算模型

分别在顺次单支路工作模式和解耦工作模式下对CRT的控制特性和谐波特性进行了计算和对比。计算分析结果表明:顺次单支路工作模式下谐波系数总能满足要求

但各控制绕组的额定值设计较困难且绕组材料浪费严重;解耦工作模式下绕组材料利用率大大提高

但却有谐波系数较大而且不可控的缺点。上述结果揭示了CRT的控制特性和谐波特性与工作模式之间的关系

为不同工作模式下CRT的控制特性和谐波特性的分析计算

以及工作模式的选择和改进提供了参考。

Abstract

Control characteristic and harmonic characteristic are two important characteristics of a controllable reactor of transformer type（CRT）.In this paper

Firstly

the winding current calculation model of CRT is given;Secondly

the traits of two typical operation modes

sequential single branch operation mode and decoupling operation mode are analyzed;Finally

combined with an example

based on the winding current calculation model

control characteristic and harmonic characteristic of CRT are calculated and compared respectively under the sequential single branch operation mode and the decoupling operation mode.The calculation and analysis results show that harmonic coefficient can always meet the demand

but it is difficult to design the rated value of each control winding

and the material waste is serious under the sequential single branch operation mode

however

the material utilization rate of winding is greatly improved

but the harmonic coefficient is larger and uncontrollable under the decoupling operation mode.The above results reveal the relationship between control characteristic and operation mode as well as that between harmonic characteristic and operation mode of CRT

and provide a reference for analysis and calculation of control characteristic and harmonic characteristic of CRT under different operation modes

and for choosing and developing the operation modes of CRT.
