Abstract :
    In this paper the effect of the automatic voltage regulator (AVR) on the following division synchronous resonance (SSR) systems can be studied. Parameters can be divided, the compensation factor. Divisions Hopf, where a pair of complex conjugate eigenvalues ​​of the linear model operating point, the left side to the right side in the complex plane, in the interest of all AVR is detected. Split Point Hopf s proof that areas with stable operating point, by the amount of interest placed AVR. Hopf dividing point spatial variation as a function of the AVR for two of the working conditions have been obtained. Time-domain simulation results based on the mathematical model of nonlinear dynamics in different and various amounts of compensation coefficients AVR agreed with the values ​​obtained from the analysis division.
