An Adaptive Harmonic Detection Method Based on Integrated Mean Value

In consideration of the problems that traditional algorithms based on instantaneous reactive power theory has slow convergence rate and the adaptive method with LPF has the drawbacks of slow dynamic response, this paper presents an improved adaptive method for harmonic detecting based on integrated mean value. Firstly, the theory of the adaptive harmonic detection method based on integrated mean value is studied in this paper. The simulation results show that the improved method has a rapid transient respon...
