DOI: 10.1051/e3sconf/201913901055 Parameters of operating conditions of electric power systems shall ensure efficient and reliable operation of both power generating companies and of consumers, which to a great extent depends on power quality. Most urgent problem in this area is currently non-sinusoidal voltage. Power quality control, development of technical measures to sustain parameters of harmonic modes in conformity with provisions of GOST 32144-2013 require calculations ...

New electrical equipment usually works alongside with the equipment that is obsolete and worn-out. Power supply systems of industrial areas of Vietnam where coal is mined are characterized by the low power quality. In Vietnam the indices which characterize the distortion of both voltage and current waveforms have standard values. The article presents the findings upon the analysis of a power supply system of a coal open-cut in Vietnam and the electrical ...

(print): 9781538643075. DOI: 10.1109/ICIEAM.2018.8728851 The paper presents an algorithm for modeling the harmonic currents of non-linear loads. Non-linear load models are necessary to plan the non-sinusoidal states in power networks to control the power quality. The measured non-sinusoidal state harmonic parameters are the source data for modeling. The analysis of these data shows that the harmonic parameters are stochastic. The non-linear load model is a set of values of active and reactive harmonic ...
