This paper provides a simulation model of the synchronization network (SN) functioning process, which is distinguished by the completeness of accounting for the functioning states. The key indicator of the synchronization network functioning process is the duration of the SN control cycle, which is understood as the time from the moment a failure occurs on the synchronization network until the moment the synchronization signal transmission mode is restored. On the basis of the developed simulation model of the synchronization network functioning process, the duration of the SN control cycle is estimated depending on the time spent in individual states of the SN functioning process and on the characteristics of individual subsystems of the synchronization system. The results obtained can serve as a basis for developing sound strategies and plans for controlling the synchronization network.
