I'm trying to model a motor accelerating from 0 full load speed. The motor data for Rr, Xr, Xm, Rs, Xs, when I start the model gives a much higher current than the LRA data. I am assuming Is=V/Ztotal where Ztotal= Zs+ (Xm*(Rr/s+Xr i)/(Rr/s+(Xr+Xm)i)). Using the impedance data I expect the calculated amps at slip of 1 should match LRA.
The impedance were reported in P.U. which i was never good at. I am using the phase voltage, and the P.U. impedances.
Any advice?
