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

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 post-fault 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.
