摘要

针对传统基于瞬时无功功率理论的ip-iq谐波检测算法对网侧电压畸变应变能力弱的缺点

提出一种基于复合三阶广义积分器的虚拟磁链观测的定向方法

利用复合三阶广义积分器和正负序分量计算模块来实现正序磁链的提取;在准确锁定电网相位角和频率的基础上

消除了传统ip-iq谐波检测算法由于电网电压不对称

波形畸变和直流偏移分量的注入等原因造成的检测误差。仿真和实验表明

改进后的方法基本不受网侧恶劣工况的影响

应用于谐波检测得到的基波电流基本不存在畸变

证明了本文提出的基于复合三阶广义积分器的虚拟磁链定向方法的有效性。

Abstract

In view of the shortcomings of the traditional i

-i

harmonic detection algorithms based on the instantaneous reactive power theory

a kind of orientation method of virtual flux linkage observation based on composite third order generalized integrator is proposed and is used in i

-i

harmonic detection algorithm.The method uses the virtual grid flux linkage as an improved link of the phase-locked loop

uses the composite third-order generalized integrator and the positive and negative sequence component calculation module to realize the extraction of the positive-order flux linkage;on the basis of accurately locking the phase angle and frequency of the grid

liminates the detection error due to asymmetrical grid voltage

wave distortion and injection of DC offset component which is caused by the traditional i

-i

harmonic detection algorithm.It is shown by the simulation and experiment that the method after modification is basically free from severe condition of grid side

the fundamental current obtained by harmonic detection has basically no distortion

can achieve real time tracking frequency variation

and the effectiveness of virtual flux linkage orientation method based on composite third order generalized integrator proposed in this paper is proved.
