| Abstract: | The present development status of harmonic current detecting methods are introduced and classifted,and a few primary harmonic detecting methods are analyzed and compared such as that based on instantaneous reactive power theory, Fourier transform, active power seperation, neural network and so on. The advantage and disadvantage of verious methods are discussed. It is pointed out the development tendency of the electric system harmonic detecting is on intelligence, multi-function, high-precision, high-rate and real time application. |
