FIELD: electrical equipment.
SUBSTANCE: use in the field of electrical engineering and power engineering. Method of detecting and eliminating an asynchronous regime at the objects of the electric power system provides for the control of the power system section and includes direct measurement of the voltage in the first node of the controlled section and calculation of its angle, obtaining the voltage value in the second node and calculating its angle, calculating the angular difference between the voltages of the first and second nodes, and forming a control action to eliminate the asynchronous mode at a time when the difference in the angular stresses of the nodes becomes equal to or exceeds a predetermined value. In this case, the voltage measurement in the second node of the monitored area is performed at the output of the rotor angle rotation control means of the generator.
EFFECT: technical result is increased reliability, accuracy, selectivity and adaptability of detection and elimination of the asynchronous regime of the power system.
