Dynamics of a power synchro system with shunt-connected rotor resistancesߞDynamic analysis and experimental results

In the companion paper, the general model of a power synchro system with shunt connected rotor resistances is developed and steady-state analysis outlined. In this paper dynamic behaviour of such a system is examined using eigenvalue analysis as well as by simulation of the system non linear equations. The effect of the system parameters on stability is investigated. The system is simulated using the System 360/Continous System Modeling Program [1] for different dynamic situations. Experimental results on an actual system corresponding to the theoretical simulation are presented. A comparison is made between the performance predicted from the nonlinear and linearized equations of the system for different amounts of torque disturbances. It is hoped that the analysis presented together with the experimental results will give a better insight into the operation of such systems.
