FIELD: electricity.
SUBSTANCE: according to the method for synchronisation of an excited synchronous machine with the mains one determines the relative angle, relative speed and relative acceleration. One plots the reference model movement trajectory for the parameters of relative movement of the synchronous machine and the mains voltage vectors. Based on the plotted trajectories all the parameters of relative movement of the synchronous machine and the mains voltage vectors are gradually and simultaneously brought to zero values due to unipolar adjustment of voltage misbalance on the synchronous machine shaft in accordance with the obtained trajectories of the reference model movement. Notably, one verifies whether the relative angle, relative speed and relative acceleration are equal or nearly equal to zero values at the moment of achievement whereof the synchronous machine is activated for operation in parallel to the mains.
EFFECT: practical implementation simplification, accuracy and response speed increase.
