PROJECT TITLE :

Real-Time Hardware-in-the-Loop Simulation of Permanent Magnet Synchronous Motor Drives under Stator Faults - 2017

ABSTRACT:

Hardware-in-the-loop (HIL) testing ways can facilitate the event of control ways in an exceedingly safe and inexpensive environment significantly when extreme operating conditions such as faults are considered. HIL strategies rely on accurate real-time emulation of the equipment under investigation. However, no validated tools for real-time emulation of electrical drives under fault conditions are on the market. This paper describes the implementation of a high-fidelity real-time emulator of a permanent-magnet synchronous motor drive in a platform appropriate for HIL tests. The emulator is capable of representing the drive operation under both healthy conditions and throughout interturn stator winding faults. Nonlinearities due to saturation, higher order harmonics, slotting effects, etc., are accounted for using four-dimensional look-up tables (LUTs) obtained by finite component analysis. The proposed model is computationally economical and capable of running in real time during a field programmable gate array platform and is validated against simulations and experimental results in a big selection of operating conditions. Potential applications of the proposed emulation environment to the development of drive management, fault detection, and diagnostic algorithms are proposed.
