Induction machine fault diagnosis using microcontroller and Real Time Digital Simulation unit

Abstract

In an approach to diagnose the various types of fault, generally occurred in Induction machines, this paper describes a monitoring and analysis system. The induction machine model and its various types of fault are simulated using a Real Time Digital Simulation (RTDS) unit. The signal corresponding to the simulation can be taken out of the RTDS unit which is interfaced with a microcontroller for its acquisition in a PC. The PC based software can store it and the fault detection algorithm (sequence component based) runs over it to detect and diagnose the fault. Encouraging results are obtained.
