| Abstract: | The power system harmonic detecting is the foundation and the major basis of the technique of active filtering, and the accuracy of the detecting play an important role in the harmonic compensation. It is proved in the theory and practice that the detecting accuracy and the speed of dynamic response of harmonic are closely related to the methods. In this paper, the current methods are classified, and a few major harmonic detecting methods are analyzed in detecting accuracy, detecting speed, delay and real time. It has pointed out the advantages and disadvantages of different methods. In the end of this paper, the development tendency of the electric system harmonic detecting is prospected. |
