This paper proposes a useful analog induction machine model which is u
sed in real-time analog power system simulators. The operation of the
induction machine model is stable by for large changes of an outside n
etwork impedance, and this model is accurate due to a length of 12 bit
s of data for the parameter setting. The steady state and the transien
t state response of the induction machine model are tested and evaluat
ed.
