    Abstract: To meet the requirements of power quality in the aspects of real-time detection, dynamic response and precise tracking for harmonic
detection, this paper used the characteristics that the neutral network could quickly and fully approached to any nonlinear to optimize system parameters by the design of training samples. This paper gave a kind of new type of harmonic detection technique. Simulink in Matlab software was used to build the simulation model to display the signal treating process and results, which verifies the feasibility and superiority of the method.
    Key words: harmonic current detection; back-propagation neutral network; active power filter; Matlab/Simulink software
