Harmonics in high voltage networks

The paper presents the results of studies in the area of harmonics in HV networks that were obtained at the Siberian Energy Institute. The studies have been performed based on the method of harmonic distortion powers that was developed at the Siberian Energy Institute. It contains the notions of distortion power generation and absorption The method forms the basis of the software package “Harmonics” that is applied for calculation, analysis and study of the harmonic modes in networks of a complicated configuration. The probabilistic mathematical models of loads are suggested. The probabilistic approach to calculation of harmonic modes in the HV network is considered. High levels of harmonics are typical of the nodes with a lower value of the distortion power absorption. The harmonic voltage levels can be normalized in both operating and planned networks of a complicated configuration in a centralised way
