This article discusses the phenomenon of a two-frequency asynchronous mode as the most typical and common in power systems. The analysis of methods of registration and elimination of the asynchronous mode and a description of their principles of operation of these methods are carried out. The conditions for the occurrence of an asynchronous mode are considered and analyzed, the main signs of the transition of an electrical network to an asynchronous mode are highlighted. On the basis of the RUSTab software package, an experiment was modeled that simulates the asynchronous mode and synchronous oscillations in the network section included in the IES of the East. The critical values of the parameters of the elements of the experimental network are estimated. The composition and parameters of the control action have been determined, which makes it possible to exclude the asynchronous mode without changing the network topology. The results obtained show the efficiency of using asynchronous mode methods based on the constructed model.
