Analysis of Electrical Characteristics of Supply Network for a Group of Electric Drives With a Periodic Load: Operation under Different

In the article, an electrical network of an enterprise, consisting of an infinite bus, a transformer and a group of electric drives with a periodic load, has been analyzed using a developed computer model. In the study the peak values of the rms current, the minimum voltage value, the analysis of the power and energy consumption has been used as performance indicators. The simulation considers a group of electric drives with a rectifier assembled according to the Larionov scheme and a group of electric drives with a common DC link operating with a periodic load with different shares of the generator mode using load working phase desynchronization. Analysis of the obtained results showed that an electric drive with a common DC link offers the lowest peak current value for any value of the share of the generator load mode. Moreover, it produces the lowest power consumption with generator mode shares from 20% to 80%.
