| Abstract: | Firstly the ip-iq harmonic detecting algorithm is introduced.A modified method of harmonic detecting is proposed for the characteristics of power system operation.Then a simulation of this new method is carried out and good results are obtained.The improved method will have a great effect on the practical realization.It can simplify the harmonic detection,make the actual harmonic detection to obtain faster,better results. |
