Study of Short Circuit and Inrush Current Impact on the Current-Limiting Reactor Operation in an Industrial Grid

Current-limiting reactors are widely used in industrial electrical grids to reduce the current amplitude equipment and stabilize voltage on busbar during short circuits. Their application is distinguished by high technical economic efficiency. However, mechanical damage has been observed within extensive with many induction motors internal synchronous generators. The article analyses a case study of reactor true grid circuit. An analysis damaged reactor’s previous operation had shown that there was weakening fastenings design, caused repeated starting currents A transients circuits carried out Matlab/Simulink software. simulation results showed could be critical peak an unfavourable combination configuration circuit location. prove that, for networks containing powerful generators, standardized procedure selecting current-limiting should additionally consider such factors as localization grid, effect equipment-starting possible configurations.
