A study of static stability of one-machine power system. Synchronous generator of this power system equipped automatic control of excitation (ACE) strong action. As the disturbances that cause the transition in power system was made deviation active power of the generator from the nominal power. Parameters of regulation are the generator voltage and frequency of the rotor of the generator.The power system is described by a system of nonlinear differential-algebraic equations. To simplify this the system using the method of linearization. In Matlab Simulink environment was simulated solution of the linearized system of differential equations describing the power system, with help of transfer functions. Confirmed the correctness of simulation calculations of the roots of the characteristic equation. As a result of modeling were obtained the charts of deviation the frequency and voltage from the nominal values. Were selected coefficients gain ACE.
