A New Stator Turn Fault Indicator based on Spatial Saturation Harmonic for Online Inter-Turn Short Circuit Faults Detection in IPMSM Drives

Popis výsledku v původním jazyce

This research report deals with the design and real-time implementation of a new stator turn fault (STF) indicator for online detection of inter-turn short circuit (ITSC) faults in IPMSM drives. First an evaluation function is defined based on the average value of the spatial saturation harmonic of the machine over an observation window during the online operation of the drive. Then, based on the value of the load current of the drive, a correction factor is set for each condition using a look-up table (LUT) to remove the dependency of the saturation on the load current. Finally the STF indicator is obtained by dividing the evaluation function by the correction factor for each load condition, and then the limit checking algorithm is used for decision making by setting an optimal threshold for all operating conditions. A developped hardware FFT processor is used to extract the spatial saturation harmonic from the transient inductance of the machine, estimated online using the switching of the voltage source inverter. The model is embedded into a field programmable gate array (FPGA) and experimental testing is used to evaluate the performance of the proposed STF indicator on a dedicated designed interior IPMSM with modified stator windings.
