供电系统谐波辨识的研究
|
摘要
近年来,谐波污染日益严重,但人们研究谐波问题时,往往忽略了系统的背景谐波电压。本文在假设供电系统母线段上的背景谐波电压和系统谐波阻抗相等的条件下对系统的背景谐波辨识进行了研究,并在此基础上用基于功率谱分析的谐波阻抗辨识法对系统的谐波阻抗进行了辨识,最后用基于系统谐波阻抗的谐波电流方向辨识方法对谐波电流方向进行了辨识。用此分析过程对两个变电站的背景谐波及系统谐波阻抗进行了理论分析和计算,发现得出的系统背景谐波电压和系统谐波阻抗由于系统运行方式变化或测量数据的误差等原因会发生突变。背景谐波电压的辨识对电力系统的谐波研究有一定指导作用。
During these years,the harmonic pollution get worse and worse.But when peoplestudy harmonics,they always ignore the background harmonics of power system.In thispaper we studied the background harmonics of power system,which was based on theassumed condition the background harmonic voltage and harmonic impedances ofdifferent buses were equal,then we identified the harmonic impedance of power systemusing the method which was based on the analysis of power spectrum,at last we used themethod based on the harmonic impedance to identify the direction of harmoniccurrent.And we use this analytic process to analyse and compute the backgroundharmonic voltage and harmonic impedance of two power systems.We found the resultsof the background harmonic voltage and harmonic impedances occurred mutationbecause of the change of the mode of operation or the error of measured data.Thesestudies could give some advice to harmonic research of electric power system.
