So the performance of the out of step protection is improved. The paper gives the whole developed protection scheme.

Five different types of insulation techniques are applied to 19 induction motors.

When the high frequency fluctuating signal is injected in the terminal of an induction machine, the difference of impedance between the d-axis and q-axis of the synchronous rotating reference frame can be measured. This phenomenon is explained by a high frequency model of the induction machine, which is oriented with a high frequency signal space vector. The rotor flux angle can thus be tracked by tuning the space vector of the high frequency signal. Experimental results are provided to verify that this algorithm is robust against parameters variations and load changes.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.
