摘要

本文提出了一种消除谐波平衡和不平衡电力系统中主导电流谐波的方法。本文提出了一种引入无源滤波器、正电感串联的方法，并对无源滤波器失谐值的各种结果进行了分析。提出了一种“无锁相环”技术用于谐波平衡条件下的谐波检测，而对于不平衡条件下的谐波检测则采用“快速傅立叶变换”技术。电压源变换器(VSC)的门脉脉冲采用两种不同的技术——平衡条件下的正弦脉宽调制(SPWM)和不平衡条件下的空间矢量脉宽调制(SVPWM)。利用MATLAB/SIMULINK工具给出了两种情况的仿真结果。

A Novel Shunt Hybrid Active Filter To Eliminate Dominant Current Harmonics Under Realistic Utility Conditions

This paper presents a method that aims to eliminate dominant current harmonics from both harmonically balanced and unbalanced utility conditions. This paper presents a method to introduce in series with passive filter, a positive inductance and analyzes various results for mistuned values of passive filter. A "Phase Locked Loop (PLL) free" technique has been proposed for harmonic detection in harmonically balanced conditions whereas, for unbalanced conditions "Fast Fourier Transform (FFT)" technique has been presented. Gate pulses for the Voltage Source Converter (VSC) have been generated using two different techniques-Sinusoidal Pulse Width Modulation (SPWM) for balanced conditions and Space Vector Pulse Width Modulation (SVPWM) for unbalanced conditions. The simulated results for both the cases have been presented using MATLAB/SIMULINK tool.
