The analysis of peculiarities of frequency automatics operation of power units of nuclear power plants at occurrence of system accidents is carried out. Computer models of these devices have been created taking into account their current settings at domestic NPPs, modeling of Ukrainian IPS modes by frequency under different load modes and occurrence of active power imbalances has been performed and modes that are dangerous in terms of frequency change in IPS of Ukraine have been identified. Voltage supply route for own needs of NPPs of Ukraine from ENTSO-E power systems (Poland, Romania) in case of a special system accident in IPS of Ukraine are determined. Calculated models of voltage supply routes were prepared, the use of which allowed to perform modeling of steady-state modes under atypical modes of operation of main networks and to determine routes under conditions of providing allowable voltage levels at power plants and substations of IPS of Ukraine. Based on the simulation results, the fastest and most reliable voltage supply options under different operating conditions of IPS of Ukraine after a special system accident were identified and recommendations for operational and dispatching personnel on their actions in case of a special system accident were developed to increase NPP survivability.
