Technical and Economic Analysis for Harmonic Distortion Impact and Mitigation Technique in Power Networks

Abstract:

This research proposes technical and economic analysis of harmonic distortion impact and mitigation technique in power networks. Main proposal of research is analysis of harmonic impact and harmonic solution by regarding to economic decency for investment. Parallel resonance is harmonic impact that will be mentioned in this research because it is a problem that is mostly emerged in industries that contain non-linear loads and power factor correction devices. Its impact on power network is high voltage and current amplification, which link to equipment and system failure. An application of detuned filter will be proposed to solve the problem due to its popularity (It is a basic solution, easier and more inexpensive than the other solution). Parallel resonance condition will be modeled with an industrial power network, which contains a power transformer, a non-linear load (AC drive), a power factor correction device (capacitor bank) and a harmonic correction device (detuned filter bank), by using electrical, mathematical and payback period formulas. The results will illustrated the impact of parallel resonance phenomenon due to harmonic distortion in power network.
