Abstract: This paper presents a hybrid approach to harmonic current compensation in a single-phase variable speed ac drive, which is widely used in agricultural, and textile industries. Passive power filtering utilizes contour-based design method, and is aimed to significantly reduce the 3rd, and the 5th harmonic contents, and to achieve the total current harmonic distortion after compensation of below 20%. Active power filtering is aimed to assist the passive filter to compensate for the residue group harmonic. The active filter employs a current amplifier, and the sliding window Fourier analysis (SWFA) for harmonic identification. Simulation and experimental results are presented to illustrate the effectiveness and the usefulness of the proposed method. The proposed method can cope with the speed range of 72-100% rated speed, and the load torque range of 80-110% rated torque. The results of the proposed harmonic compensation are complied with the IEEE Std519-1992 for low p!
ower systems.
Keywords: Harmonic, Hybrid power filter, Contour-based method, Sliding window Fourier analysis, AC drive.
