IMPROVING THE RESILIENCE OF SYNCHROINFORMATION SYSTEMS OF SMART POWER GRIDS AND MOBILE COMMUNICATIONS NETWORKS UNDER WARTIME CONDITIONS

The use of synchrophasors (μPMUs) for performing synchronized vector measurements in distribution electric power systems integrated with renewable energy networks is analyzed. This approach enables real-time monitoring and feedback on operational parameters, thereby allowing for timely detection of islanded networks, improved reliability, and enhanced energy efficiency. We propose an intelligent computer-integrated system that provides continuous multichannel monitoring of synchronization parameters in real-time and generation of synchronization signals for synchrophasors in intelligent electrical systems and mobile communication means with increased reliability. To generate synchronization signals with increased resilience in war conditions, it is recommended to use special GNSS radio receivers, which should be developed with a focus on resilience, to unintentional failures and targeted attacks, as well as technologies of hybrid synthesis of synchronization signals and additional methods of synchronization signal sources’ reservation. The current publication addresses the issues of measuring, monitoring and digital data processing, redundancy of reference synchronization sources, and diversifying the processes of providing synchroni-zation signals for smart grids and mobile communications networks. The created automated computer-integrated system for multi-channel monitoring of synchronization signals aggregates digital data obtained from the software and hardware tools of various manufacturers and ensures prompt and reliable diagnostics of a status of the synchronization network both in normal operation mode and in emergency situations. The placement of synchronization devices will be planned taking into consideration geographical aspects, regional features, possible replacement of satellite radionavigation systems, and the use of a greater number of primary synchronization sources. The publication presents an analysis of the results of the procedure for switching over to backup source (alternative priority) in case of emergencies. Reference 28, fig. 2.
