Analysis of Fault-Tolerant Dual Three-Phase Induction Machine Using Graphical User Interface

Abstract

This paper provides a fault-tolerant study of dual three phases induction machine in consideration of minimum-loss (ML) and maximum-torque (MT) strategy with single and two isolated neutral points under one to three open-circuit faults. For any given torque, the ML offers lower copper loss compared to MT, but a smaller range of torque operation. The machine s post-fault output is measured in terms of derating factor, minimum copper loss and minimum peak current. The simulation results supports the validity of the theoretical postfault current limits. Furthermore, in order to make the user understands what to expect when performing post-fault tolerant of a machine, the graphical representation of a program using the Graphical User Interface (GUI) was specifically created for learning and teaching aid in course such as Electric Drives and Machines.
