| Abstract: | According to the need for fast detection of harmonic currents based on LMS filter,this paper proposes an ELMS(Extrapolated LMS) algorithm formula of optimal weight for LMS,which improves the precision and dynamics performance of detecting harmonics.Theoretical analysis and simulations shows that this ELMS algorithm of harmonic detection can be adopted to the fast harmonic currents detection in power system. |
