ABSTRACT
 In recent years, there has been a considerable interest in the active power filters and power quality contaminated by non-linear load. Among the power filters, a shunt active filter is most preferable to protect the consumers from the power line with an harmonic load current. This paper describes the active power filter to comply with harmonics current regulation(IEC 61000-3-12) effective for the inverter air-conditioners whose operating current is more than 16A. The validity of the proposed compensating method has been verified by the experimental results for a shunt active power filter controlled by all pass filter to compensate a phase delay of harmonics. It was shown that the total harmonic distortion (THD) of the air-conditioner inverter has been much reduced to 6% from 54%. It is expected that the proposed active power filter is effective to the competitiveness of the air-conditioner inverter and the reduction of harmonic damage such as power line loss, power device overheating.

Harmonics and Inter-harmonics Estimation of Power Signal using Filter Banks LIN YOUNG BIN DEPARTMENT OF ELECTRICAL ENGINEERING CHUNGBK NATIONAL UNIVERSITY KOREA

ABSTRACT This paper proposes a new method which combines filter bank system and adaptive filtering for the parameters estimation of the harmonics and the inter-harmonics of power signals. The proposed method decomposes the input power signal by designing the filter bank system. This filter bank has binary tree structure, and uses the fundamental filter banks successively in each decomposing stage. The fundamental filter bank separates the odd harmonic and the even harmonic components to reduce the spectral leakage. The adaptive filter is applied to the each harmonic component for the accurate parameter estimation. And the inter-harmonic component parameters are estimated through the error signal of the adaptive filter. The amplitudes and the frequency estimation of the each harmonic and inter-harmonic are carried out by the recursive method. To demonstrate the performance of the method, computer simulations are performed to the synthesized signals.
