A new flux-based harmonic elimination technique

With the growing concern over harmonics and their effects due to the increa sing use of solid state switching devices in modem power systems, there is an increasing interest in developing new and more efficient harmonic elimin ation schemes. This paper presents a new scheme to mitigate the harmonies p resent in the system. The method uses the put cancellation and injection ca pabilities of transformers, along with the existing filter designs, to prod uce an improved performance for elimination of unwanted harmonics and noise . The robustness to time varying signals, noncharacteristic harmonics, and high-power noise makes this method highly competitive. The performance of t he proposed scheme is confirmed both by simulation on real power system har monic data and laboratory scale experimentation.
