Simulation modelling of nonlinear modes of electric network operation and processing of results using a computer program

The trend of industrial facilities development is directly related to the introduction of various semiconductor converters into power supply systems. However, the issue of influence of these converters on the quality of electric power remains relevant. Power installations of induction heating, which include thyristor frequency converter, can cause the appearance of harmonic distortions. The paper presents an active experiment on a selected object of study with a nonlinear load. This developed model is designed to determine the indicators of power quality caused by the operation of nonlinear load. The model allows carrying out studies of the influence of nonlinear load on the quality of electrical energy at different parameters of the electrical network. The results of the experiment are processed using a computer program and the analysis of data processing of the results is carried out.
