A Novel Variable Step-size LMS Algorithm of Harmonic Current Detection

ZHOU Xiao-xia LIU Xing-qiao(Jiangsu University,Zhenjiang212013,China)  
In order to improve the quality of electric energy,the harmonics of power system is restrained and compensated.A novel variable step-size least mean square(LMS) algorithm of harmonic current detection is introduced,which uses the coherence average estimation of T(n) to control the updating of the step size.It can provide a fast dynamic response while ensuring high detecting precision.Based on the Matlab simulations and DSP experiment of single-phase current,both re-sults have verified the effectiveness.
