SAŽETAK / ABSTRACT:
Precise event time determination in power systems is used for network monitoring, operation coordination, and protection, aiming to prevent major disturbances and system failures through analysis. With the increasing adoption of the IEC 61850 standard, the number of applications requiring precise time synchronization using the IEEE 1588v2 protocol (PTP – Precision Time Protocol) is growing. This protocol enables time synchronization with an accuracy better than 1 ms using both software and hardware timestamping. A hardware implementation of the PTP protocol, which utilizes lower OSI model layers for generating time markers, can improve synchronization accuracy to better than 20 ns.
To enhance Ethernet interface speeds in TZ600 distance protection devices, it was necessary to test new hardware components that enable higher Ethernet speeds, particularly new processor systems and corresponding PHY interface digital blocks. In addition to examining transmission speed, it was also necessary to determine time synchronization accuracy for different hardware configurations. This paper presents the fundamental capabilities of new hardware platforms based on ARM SoC (System on Chip) Zynq 7000 and Zynq UltraScale+ processors. It also describes the test setup for evaluating the PTP protocol, along with the obtained results—achieved synchronization precision—and compares them with previous tests to select the optimal configuration.
