Rules of Harmonic Longitudinal Propagation in Various Voltage Classes

Abstract:

Different voltage-class buses of transformer substations which are established based on harmonic voltage distortion to limit amplitude via national standards, so study of harmonic longitudinal propagation (RHLP) is essential to power networks. In order to research RHLP, building models of different electrical components which are harmonic sources, equivalent generators, distribution parameter overhead lines (DPOL), transformers, and loads and so on are crucial. This paper proposes a method which utilizes the principle of electric circuits' ohm' law, series resonance and parallel resonance to study RHLP. Finally, according to Henan province power networks frame, a model is constructed in the simulation software packages PSCAD/EMTDC to verify the method. Furthermore, using MATLAB calculation and PSCAD/EMTDC simulation conclude RHLP in different voltage classes.
