Induction Motor Parameter Identification from Operational Data

By Tania Parveen, Gerard F. Ledwich and Edward W. Palmer


Among the parameters of an induction motor, the dynamics are largely characterised by Inertia (H) and torque-damping factor (B). It is now simple to get substation bus bar data (current and voltage) by using phasor measurement device. This paper uses that data to identify an induction motor model in frequency domain and from the model of the induction motor one can estimate B and H. In this paper estimation of parameter B and H from the frequency domain model of an induction motor is shown for a fan load by using simulation model and also a 1.5kW real motor in a Queensland University of Technology (QUT) laboratory
