摘要

为了限制长距离输电线路上过电压和补偿线路充电功率

需要在超高压交流输电线路上装设高补偿度的并联电抗器。磁控式并联电抗器由于受铁心饱和特性影响

网侧绕组电流中不可避免地含有高次谐波。笔者以世界上首套500 k V可控示范工程为基础

提出一种基于2D有限元场路耦合方法

计算分析可控高抗控制特性

并与江陵荆门换流站500 k V磁控式电抗器实测结果对比。最后

基于上述方法对超高压750 k V可控并联电抗器网侧绕组励磁特性及谐波含量进行分析

通过与现场运行实测数据对比

验证计算方法满足工程应用的有效性。

Abstract

To restrict over-voltage and compensate line charging power

it is necessary to install high compensation shunt reactors on ultra-high voltage AC transmission lines. Due to the saturation characteristic of the core during working process

the magnetically controlled shunt reactor（MCSR）contains higher-order harmonics in its high voltage windings. In this paper

the 500 k V MCSR demonstration project is taken as an example

and a finite element-based field-circuit coupling method is proposed to analyze the controlling characteristic of the high voltage winding. The amplitude and frequency of the harmonic in the current of the high voltage winding are calculated with this method. The calculated results are compared with the measured ones of the 500 k V MCSR in Jiangling Converter Station to verify the validity of the proposed method. In addition

the excitation curve and the harmonic current of a 750 k V MCSR are calculated with the proposed method

and the results agree with the measured data.
