As power utilities modernize their grids, many are transitioning to digital substations and implementing substation automation powered by digital monitoring and protection and control (PAC) applications, leveraging IEC 61850 standards. This transformation requires precise coordination of intelligent electronic device (IED) activities, data measurement and resource scheduling, orchestrated between IEDs in substations and control software in substations, control center and data centres. Recognizing that time synchronization has become essential for power grids and other critical infrastructure, this presentation looks at the foundations of a robust infrastructure and sync planning to ensure delivery of required precise timing.
