Belden Inc. announced today that its GarrettCom brand has been accepted as a Charter Member in Symmetricom’s SyncWorld Power Ecosystem Program following successful demonstration of interoperability with Symmetricom’s SGC-1500 Smart Grid Clock. GarrettCom’s 10-Series managed switches use IEEE 1588 to deliver a solution using delays of less than 50 nanoseconds, providing power transmission and distribution customers the precision timing needed to operate and manage today’s smart grids.
IEEE 1588v2 is a breakthrough timing protocol that offers sub-microsecond synchronization for clocks in various substation and power delivery devices such as sensors and actuators over an Ethernet network. The sub-microsecond timing accuracy of these substation-hardened switches exceeds the requirements of “next generation” IEC 61850-3 specifications. Timing features include master clock, boundary clock, and transparent clock.
Sub-millisecond timing synchronization is critical for power suppliers as it enables the operator to reconstruct the sequence of events after an incident on the grid or to monitor smart grid performance to make adjustments and improvements. The 1588v2 protocol is important in IEC 61850 compliant systems where it supports seamless line switchovers and other sensitive events requiring precise timing. It is a critical component for allowing utilities to offer the precision timing required to support the control algorithms required for modern power management and delivery systems.
“Increasing automation is likely to require synchronization at a rate in the tens of nanoseconds. It is incumbent upon equipment suppliers such as Belden and Symmetricom to develop, market and support the standards-based hardware and software required to maintain that level of precision,” said Carey Trost, Belden Director of Product Line Management. “With Belden’s membership in the Symmetricom SyncWorld Ecosystem Program, our power transmission and distribution customers are assured that GarrettCom’s robust substation-hardened switches and Symmetricom’s Grandmaster timing clock will interoperate seamlessly. Together we offer our customers the best tools to access, monitor and maximize the performance of their grids.”
