Introduction

The Kyland total solution for smart grid precise clock synchronization is based on the IEEE 1588 v2 and G.8261 protocols that is capable of providing precise timing signals over an Ethernet network and will become part of IEC 61850 solution. Kyland’s new product can act as boundary clock (BC), E2E transparent clock (E2E TC), and P2P transparent clock (P2P TC), and support Timing and Synchronization Aspects in Packet Networks (G.8261). With this function, the accuracy of the synchronization is within 100ns and the reliability of the whole timing system has been highly improved. To support the large quantity of existing legacy IRIG-B IEDs, Kyland Clock Card solution will give our customers a fast and cheap migration path based on IEEE1588 v2.
Kyland IEEE1588 v2 Applications and Solutions

In this diagram, all Kyland SICOM3024PT worked as BC (boundary clock) and TC (transparent clock) are synchronized with IEEE1588 v2 and G.8261 for IEC61850 Station Bus and Process Bus applications.

Time Synchronization Functions
1. Significantly increasing the synchronization reliability and precision, the accuracy is within 100ns.
2. In case that the master clock is unavailable, the switches will continue to offer unified precise clock information for all end devices, ensuring the normal operation.

Synchronous Industrial Ethernet Technology
Guaranteeing the high accuracy frequency synchronization.

Solution of Precise Time Synchronization for IEDs.
Providing clock card for IEDs to realize the whole system synchronization much easier.

Outstanding advantages of synchronous Ethernet

The biggest advantage of Kyland precise clock synchronization solution compared with other vendors is that this solution supports not only IEEE1588 v2, but also synchronous Ethernet with a reliable hardware-based technology. 
The synchronous Ethernet technology realizes the frequency synchronization in physical layer, and IEEE1588 v2 only need to adjust the phase inaccuracy. This can reduce the network traffic efficiently. During the PTP transparent clock transmission, it is proved that adjusting the switch’s own atomic clock according to the master clock is absolutely necessary. Without this function, time drift will occur during the switches transmitting the timing signals coursing the failure of whole timing system for all IEDs and end devices.
