[Abstract]:Harmonic suppression is one of the important measures to construct high power quality power grid. Aiming at the problem of harmonic hazard in power network, firstly, based on the traditional harmonic theory, the generalized harmonic theory is developed. The basic theory of generalized harmonic current and the realization process of generalized harmonic current detection are described in detail. The necessity and effectiveness of generalized harmonic current as command current signal to realize power quality comprehensive compensation are analyzed. The hardware circuit and software system of generalized harmonic current detection circuit are designed. Based on generalized harmonic theory, the simulation and experiment of instruction current detection of generalized active power filter (GAPF) are carried out. The simulation and experimental results show that the algorithm can detect the generalized harmonic current without principle error in real time, and has the advantages of high accuracy, good real-time performance, simple algorithm and convenient hardware implementation.
