Detection of Inter-turn Short-circuit Faults in PMSMsBased on Instantaneous Reactive Power
Reliable stator faults diagnosis is important for machine drives.This work presents an inter-turn short-circuit faults detection and faulty phase location method for PMSMs with neutral conductor, based on the percentage of the second harmonics in the three phase instantaneous reactive powers, defined in the abc frame of reference.A faulty PMSM model which is widely used for the detection of inter-turn short-circuits is used to build a simulation setup in MATLAB/Simulink.From the theoretical analysis and the simulations, the second harmonics in instantaneous reactive powers are proven to be the characteristic feature for fault detection.Simulations at different operating conditions show that the percentages of the second harmonics to their dc components in phase instantaneous reactive powers are more reliable than the second harmonic amplitudes themselves for the inter-turn short-circuits detection and location.
