Harmonic analysis in power systems is a challenge that is always evolving due to a constantly changing power grid. Advances in power electronics have led to the installation of many new non-linear power loads, such as power converters, arc furnaces and motor drive systems, which in turn change the existing infrastructure and inject new types of harmonics. This study analyzes a static Kramer drive system for its harmonic behavior. The system is broken down component-by-component and analyzed. The analysis includes classical harmonics of integer multiple of the fundamental frequency as well as sub-harmonics and interharmonics. This paper shows that there are significant harmonic issues in a static Kramer drive that are likely to be present in similar drive systems.

520 $a Harmonic analysis in power systems is a challenge that is always evolving due to a constantly changing power grid. Advances in power electronics have led to the installation of many new non-linear power loads, such as power converters, arc furnaces and motor drive systems, which in turn change the existing infrastructure and inject new types of harmonics. This study analyzes a static Kramer drive system for its harmonic behavior. The system is broken down component-by-component and analyzed. The analysis includes classical harmonics of integer multiple of the fundamental frequency as well as sub-harmonics and interharmonics. This paper shows that there are significant harmonic issues in a static Kramer drive that are likely to be present in similar drive systems.
520 $a Due to the unknown frequencies at which interharmonics and sub-harmonics arise it is difficult to estimate the magnitude and phase of these harmonics. It is proposed that state estimation techniques such as digital filtering coupled with windowing techniques can be used to properly pinpoint the frequency components, magnitudes and phases of harmonics, interharmonics and sub-harmonics in the motor drive systems. Once identified, the harmonics, interharmonics and sub-harmonics can be eliminated by means of passive filtering or self-tuning active filtering.
520 $a The optimal methods of estimation of harmonics, interharmonics and sub-harmonics will be both developed analytically and through the means of simulation with the use of CAD tools such as PSCAD and MATLAB. The development of the optimal techniques for estimation of harmonics, interharmonics and sub-harmonics for that static Kramer drive will aid in estimation of harmonics, interharmonics and sub-harmonics in similar motor drive systems.
