The article content different methods of modeling elements of the electrical network in the presence of harmonics in voltage and current, but also studied and compared. It is shown that when calculating the power network should be considered a surface effect and the effect on the occurrence of eddy currents. When accounting for these factors, the calculation error mode power consumption is significantly reduced.
The optimization of reactive power compensation in the presence of harmonics in the electrical network complex is a complicated computational problem. The authors propose a calculation method that significantly reduce the computation procedure and still get the desired result as the choice of device parameters for reactive power compensation and harmonics filters.
