成果简介	NOVELTY - Invention relates to electrical engineering and can be used for automatic control of synchronous generator rotor speed. Technical result is achieved when using the method, which consists in the fact that in the synchronous generator rotor speed controller with a proportional-integral-differential control algorithm, the load angle of the synchronous machine δ is measured using a sensor, signal from which is transmitted to microcontroller with predictor time constant determining unit, signal from which is multiplied by the signal of the linear predictor, which is connected in series to the electronic amplifier. Time constant of the predicting element is set as the period of natural oscillations of the rotor of the generator from the ratio where ƒp is frequency of natural oscillations of generator rotor, Hz, ω0 is rated angular frequency of rotation of generator rotor, rad/s, Tje is equivalent constant of mechanical inertia of unit, s, – synchronizing power, p.u., where Eq is generator EMF, p.u., Ug is generator voltage, p.u., Xd is inductive resistance of the generator along the longitudinal axis, p.u., δ is generator load angle (angle between electromotive force and generator voltage). Controller for implementing the method comprises an algebraic adder, a control element with PID control, a predictive element, as well as in-series connected unit for calculating the frequency of natural oscillations of the generator rotor and the unit for calculating the time constant of the predictive element. Input of the unit for calculating the frequency of natural oscillations of the generator rotor is connected to the output of the load angle signal of the synchronous generator. Output of the unit for calculating the time constant of the predictor is connected to the second input of the predictor. USE - Electrical engineering. ADVANTAGE - Higher accuracy of control. 2 cl, 6 dwg
