description: The topic of the final qualification work: "Research of asynchronous modes of power systems and the development of measures for their elimination with AEOAO, devices." The theme of the study is the 220 kV intersystem transit "Pechora SDPS - Ukhta - Mikun", and the object of the study is the automatic devices for eliminating the asynchronous mode, which must be installed on the new line of the 220 kV overhead line Pechora State District Power Station - Ukhta, their settings and the principle of operation in the event of asynchronous modes. Purpose of the work: Study of dynamic stability of intersystem transit, selection and adjustment of automatic devices for elimination of asynchronous mode for overhead lines 220 kV Pechora State District Power Station - Ukhta. The analysis of dynamic stability was carried out on the basis of modeling various disturbances and calculating transient processes in these modes. The use of AEOAO devices was chosen as an event to eliminate asynchronous modes. As a result, the modes were identified in which the dynamic stability was violated, the types of AEOAO devices were selected to protect the investigated power transmission line and their settings were calculated. Thus, the study of the dynamic stability of the transit, the selection and adjustment of automatic devices for the elimination of the asynchronous mode allows to ensure the reliable operation of the newly introduced power transmission line.
