Power Hardware-in-the-Loop based Emulation of An Induction Machine with Stator Winding Faults

The induction machine (IM) is commonly adopted in industry, which plays an important role in energy conversion between mechanical power and electrical power. Asymmetrical faults caused by internal failures commonly occur in IMs. Such faults not only reduce the working efficiency and cause excessive heating, but also cause potential hazards preventing continuous operation and safety problems. In this paper, a power electronic converter-based IM power hardware-in-the-loop (PHIL) emulator is developed to emulate an IM with internal faults. The IM mathematical model with an inter-turn short circuit of the stator winding is established and verified in the built IM emulator. A comparison of the emulator results with simulation results and actual experiments demonstrates the validity of the proposed solution.
