Dynamic modeling and analysis of re-switching of an induction motor running at full load Condition

Abstract

The paper is about the study of the re-switching characteristic of an induction motor. The aim of this research is to analyze the re-switching characteristics of an induction motor and investigate the transient phenomena that occur during the switching process. The motivation behind this research is to understand the factors that influence re-switching and how it can be optimized to avoid disconnection of the machine from the power supply. To achieve this goal, the researchers performed simulations of the machine start-up and calculated various parameters such as initial torque values, steady-state values, speed vs time graph, stator and rotor flux details, and stator and rotor current details. The researchers then compared these parameters with re-switching simulated parameters of induction motor and observed transients in the re-switching case. The methods used in this study involved simulating re-switching in a re-connection situation and analyzing the resulting data using graphs and tables. The study found that different parameters influence the re-switching process and that quick re-switching is critical to prevent the machine disconnection.
