This article is dedicated to the simplification of calculating the modes of higher harmonics in electric power grids. Non-sinusoidality of voltages and currents is one of the most important indicators of electric energy quality as it affects the operation of almost all kinds of collectors. Power quality depends on the electricity production process, its transportation to the place of sales as well...
Voltage flicker and harmonics are the power quality problems which are introduced to the power system as a result of nonlinear and stochastic behavior of the arc furnace operation. In the first part of the paper, different arc furnace models with different level of complexity, for flicker study are reviewed. Simulation results are also provided. In the second part of the paper, a new developed time...
