I'm recently making research on induction motor parameter identification and found a research matching my purpose, but I don't know how to build this "ABCabc model of an induction motor", which is the key to get the caculated current. Does anyone know this model of induction motor?
I attached the picture mentioning this phrase and the full text as well. It's from Dr. Ahmed M.Alturas.
One more thing worth mentioning is that Dr. Alturas proposed the method to get the electrical parameters of the induction motor under steady state without the need of prior knowledge. I tried to implement his algorithms but failed. I've tried the transfer funciton model and electric circuit model of induction motor under steady state, but the parameters didn't converge. I feel like the model is the key. Once this ABCabc model is used, it'll converge.
ABC and abc could be considered primary and secondary phases of three phase transformer analogy applied to induction motors as the working and designs are identical based on induction principle with same OC and SC test applied to find the machine parameters……
Thanks. And for inverse Γ-equivalent circuit of induction motor, is it possible to identify all the electrical the parameters under steady state(constant speed) knowing the stator voltage, current and speed? I tried using PSO algorithms to update the parameters and used the transfer function of the circuit to get the current but the parameters combinations didn't converge to real values.@ Bhupendra Desai
I have some experience with that topic. I believe that some heuristics are necessary. For example the stator and rotor resistances are equal and also the leakage inductances (assuming T-equivalent circuit). The main inductance is several time larger than leakage inductance. Moreover, the resistances are temperature dependent. Not every algorithm is converging and the fitness function is very important. I have good results with covariance matrix adaptation evolution strategy (CMA-ES).
